It is one of a very few European nodule Ossidianas with a deep structure and the only one that resembles the dragon eggs from the TV series “Game of Thrones” and “House of the Dragon”. That's why everyone who sees it calls it “Dragonglass”.\nCharacteristics:\nThe colour, texture and shape are as follows: It is, at first glance, unmistakably similar to tektite. The colour banding and degree of crystallinity vary, with the Ossidiana coming in dark olive green, grey, or black hues and boasting a lustrous quality. Ossidiana vetro di drago has a pronounced deep structure and is not translucent due to the darkness of the glass. The Ossidiana vetro di drago is round, egg- or teardrop-shaped. The average weight is 40 grams, and nodular Ossidiana has only been found in a few places outside of Europe, which makes it all the more special. These includes Ossidianas in Indonesia (Agni Manitite), USA (Saffordite and Apache Tears Ossidiana), Peru (Macusanite), Colombia (Calitite), Nicaragua (Marekanite), Azerbaijan, and China.\nHistory:\nThe Ossidiana vetro di drago comes from Milos Island in Greece. The submarine lava dome originates from an underwater volcano and is estimated to be 1.5 million years old. At the dawn of the Neolithic age, circa 8000 BC, Ossidiana mining and trading began on Milos. Tools, small knives and arrowheads made of Milos’ Ossidiana have been found in Crete, Egypt and elsewhere. A rare and unique opportunity: Milos is rich in Ossidiana, but it mostly consists of Ossidiana flakes (broken glass fragments). Of these, only about 1% are structured and round Ossidiana. And of that 1%, only 1% are undamaged, making them extremely rare. What also makes these pieces a unique and highly sought-after opportunity with high appreciation potential is the fact that pearlite mining will soon begin at the site, leading to their future unavailability.\u003c\/p\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58027917771077,"sku":"XDO001","price":1674.09,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/20605_dragonglass-obsidian-400g--9pcs--milos--greece.jpg?v=1779378241"},{"product_id":"biliotnite-50g-0-3g-vel2","title":"Biliotnite 50g (0-3g) -

When lightning strikes, the temperature reaches up to 30,000 °C and melts the silica particles. The lightning heats the sand so rapidly that it melts and then quickly cools, forming tubes, cavities, or other glassy structures called fulgurites. These are systematically classified as so-called shock-metamorphosed rocks.\nFulgurites can vary in length and thickness depending on the intensity and duration of the lightning strike. The color usually ranges from transparent to pink or brown to black, depending on the impurity content in the sand.\nThe inner walls of fulgurites are lined with a glassy layer formed by the melting of the sand. Traces of partially molten sand grains are visible on the outer surface. Fulgurites are relatively fragile and break easily, which makes it difficult to collect larger pieces and increases their price.\u003c\/p\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58027971903813,"sku":"FVEL01","price":355.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/52634-7_photoroom-20250801-164514.jpg?v=1779378633"},{"product_id":"slovak-obsidian-hedgehog-475g-objvel6","title":"Slovakian Obsidian – Hedgehog – 47.5g – OBJVEL6","description":"\u003cul\u003e\n\u003cli\u003eLocation: Carpathians, Slovakia\u003c\/li\u003e\n\u003cli\u003eTotal Weight: 47.5g\u003c\/li\u003e\n\u003cli\u003eWeight range: 4-7.5g\u003c\/li\u003e\n\u003cli\u003eNumber of pieces: 8\u003c\/li\u003e\n\u003cli\u003eDETAILED DESCRIPTION\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSlovakian Obsidian – hedgehog\nThis recently discovered type of Obsidian is among the most beautiful Obsidians in the world. It is distinguished from other Obsidians by its distinctive deep texture, which resembles South Bohemian Moldavite (it is very similar to the Besednice Jezkovna). Its sculpture was formed by rapid cooling, surface cracking, and the subsequent slow action of soil acids at the specific site, just like in the case of Moldavite. The exact location is currently kept secret to protect the area from diggers and potential landscape devastation. We believe that once the precise discovery site is revealed and scientifically examined, interest in this Obsidian with its rare and aesthetic appearance will grow rapidly worldwide – especially due to its significant potential for use in the jewelry industry.\nQuantity and exceptional pieces\nAn estimated 5 kg has been discovered. The average weight of individual pieces is around 3 g. Finds exceeding 10 g are rare. The largest specimen discovered so far weighs an incredible 54 g.\nForgeries and authenticity guarantee\nWe have recorded the presence of forgeries on the market, created by drilling into known Obsidians from Brehov. Forgers attempt to imitate the sculpture, but the result is usually imperfect – drill marks are often visible. A layperson may not recognize a forgery at first glance. Therefore, we recommend being careful about the origin of purchased Obsidian. Our specimens come directly from the finder and we guarantee their authenticity.\nThis distinctly sculpted Obsidian was described in the 2024 book Glassy Wonders.\nEastern Slovakian Obsidian – volcanic glass with exceptional color spectrum\nGeneral\nObsidian is a type of volcanic glass, a rock that is formed as a result of magmatic activity when hot lava comes into rapid contact with a cold environment and then solidifies rapidly. The rock is very rich in silica compounds and is a natural form of glass. It is typically dark in colour, ranging from black, grey or red. It is usually opaque, but its transparency increases as the iron oxide content decreases.\nHistory\nThe occurrence of Obsidian in Slovakia is relatively small compared to other local neovolcanics. Our ancestors used it to make cutting tools as early as the Palaeolithic, but it has been shown that these tools were also used during the Neolithic. In Europe, there are only a limited number of primary occurrences of Obsidian suitable for the production of cutting tools, mainly scrapers, spearheads or knives. It is clear from the results of ongoing research that the importance of Eastern Slovakian Obsidian as a raw material for the production of chipped tools has far exceeded its local significance. Therefore, Eastern Slovakian Obsidian was distributed throughout Central and Eastern Europe and across the Balkans to the Mediterranean.\nA little chemistry\nObsidian is the product of highly acidic lavas of Neogene volcanism. Their origin is closely linked to rhyolite volcanism. Its occurrences form the peripheral parts of larger volcanic bodies, mainly composed of rhyolite. The nests of Obsidian nodules, incorrectly referred to by collectors as mounds, are usually found in rhyolite tuffs, from where it often weathered as a more resistant material, and therefore today its shape and surface (sculpture) often resembles Bohemian Moldavite.\nThe Obsidian of Eastern Slovakia belongs to a group of unaltered acid volcanic glasses with a silica (SiO2) content of about 80%. The higher acidity of the local lavas has caused the Obsidians to have a higher SiO2 content and a lower water content than the world average. This is the reason for their greater durability and suitability for the production of chipped tools. The water content of Obsidian is unusually low. The H2O content varies between 0.19 and 0.31 %. The density varies between 2.3 and 2.4 g\/cm³. Porosity is well below 1 %, and hardness is between 5 and 5.5 on the Mohs scale.\nThe local Obsidian is transparent. Depending on its chemical composition, its colours range from black, to grey, to bluish and greenish, sometimes with silvery highlights. No other Obsidian in the world offers such a colour spectrum!\nInteresting \/ Potential\nAs chance would have it, the occurrence of Obsidian in Slovakia dates back 15,000,000 years ago, around the same time as its Czech \"brother\", Moldavite, to which it is often compared for its appearance, and at a certain distance and under the right light they are indistinguishable from each other. But of course on closer examination the differences are clear and there can be no confusion.\nInterest in Obsidians in general is growing both in Europe and worldwide. The Slovak ones are enhanced by their rare occurrence, limited quantity, unique colour and the aforementioned resemblance to Moldavite. Its current low price makes it an ideal investment stone for the future.\nObsidian is easy to work and polish, and as a raw material it is truly suitable for jewellery and haberdashery purposes. It is also used to make replicas of Palaeolithic cutting tools, stone beads and jewellery. Obsidian can be collected at individual sites in the form of small boulders from 1 to about 20 cm in diameter. However, most of the mounds are between 1 and 5 cm. Their predominant colour is black or blackish grey. The cut stones achieve a high polish and the cut yield is comparable to commercial coloured Chalcedony.\nIt can be used not only in the form of plain cabochon cuts or tables, but since it is transparent, it can also be faceted in the form of rout and step cuts. Faceted stones are very spectacular and surpass in appearance the dark gneisses and morions. Due to its easy workability, it is also a suitable raw material for plastic cutting of small figures, so-called glyptics.\nIn any case, it deserves to be promoted as one of the very interesting materials used since the Stone Age. Although interest in natural glass is growing mainly thanks to tektites, the others are also being mentioned alongside them. The scientific community has organised several conferences dedicated to natural glass research. In 1987, one of them was held under the auspices of Charles University in Prague. For this conference, silver jewellery was produced by the Granat cooperative in Turnov, the dominant stone of which was Obsidian from Eastern Slovakia.

The rock is very rich in silica compounds and is a natural form of glass. It is typically dark in color, ranging from black to gray or red. It is generally opaque, but its transparency increases with decreasing iron oxide content. History The presence of obsidian in Slovakia is relatively limited compared to other local neovolcanites. Our ancestors used it to produce cutting tools as early as the Paleolithic (2,500,000 years ago), but it has been shown that these tools were also used in the Neolithic (5,000 years ago). In Europe, there is only a limited number of primary obsidian deposits suitable for the production of sharp tools, especially scrapers, spearheads or knives. Research findings clearly show that the importance of Eastern Slovak obsidian as a raw material for the production of chipped tools far exceeded its local significance. For this reason, Eastern Slovak obsidian was distributed throughout Central and Eastern Europe and across the Balkans to the Mediterranean. A little bit of chemistry Obsidian is the product of highly acidic lavas of Neogene volcanism. Its origin is closely linked to rhyolitic volcanism. Its deposits form the peripheral parts of large volcanic bodies composed mainly of rhyolite. Obsidian nodules, mistakenly called \"mounds\" by collectors, are generally found in rhyolitic tuffs, from which they have often been eroded due to their greater resistance; for this reason, their shape and surface often resemble Bohemian moldavite. Eastern Slovak obsidian belongs to the group of unaltered acidic volcanic glasses with a silica (SiO₂) content of approximately 80%. The higher acidity of local lavas has resulted in a higher SiO₂ content and lower water content in obsidians compared to the world average. This is the reason for their greater durability and suitability for the production of chipped tools. The water content of obsidian is unusually low. The H₂O content varies between 0.19 and 0.31%. The density varies between 2.3 and 2.4 g\/cm³. Porosity is well below 1% and hardness is between 5 and 5.5 on the Mohs scale. Local obsidian is transparent. Depending on the chemical composition, its colors vary from black to gray, to bluish and greenish hues, sometimes with silvery reflections. No other obsidian in the world offers such a range of colors! Curiosities \/ Potential By a surprising coincidence, the presence of obsidian in Slovakia dates back to approximately 15 million years ago, more or less the same time as its Czech \"sister,\" moldavite, to which it is often compared in appearance. At a certain distance and with the right lighting, the two stones may seem indistinguishable. Of course, upon closer inspection, the differences become obvious and they cannot be confused. Interest in obsidian in general is growing both in Europe and in the rest of the world. Slovakian ones are valued for their rarity, limited quantity, unique color, and resemblance to moldavite. Their current low price makes them an ideal stone for future value appreciation. Obsidian is easy to work and polish and as a raw material it is truly suitable for jewelry and handicrafts. It is also used to make replicas of Paleolithic tools, stone beads, and jewelry. Obsidian can be collected from various sites in the form of small pebbles from 1 to about 20 cm in diameter. However, most nodules measure between 1 and 5 cm. Their predominant color is black or grayish-black. Cut stones achieve a high polish and the cutting yield is comparable to that of commercial colored chalcedonies. It can be used not only in the form of simple cabochons or tables, but, being transparent, it can also be faceted with round and step cuts. Faceted stones are very spectacular and surpass dark gneisses and morions in appearance. Thanks to its easy workability, it is also a suitable material for plastic carving of small figures, the so-called glyptics. In any case, it deserves to be promoted as one of the most interesting materials used since the Stone Age. Although interest in natural glass grows mainly thanks to tektites, other forms are also increasingly mentioned alongside them. The scientific community has organized several conferences dedicated to research on natural glasses. In 1987, one of these took place under the patronage of Charles University in Prague. For this conference, the Granat Turnov cooperative produced silver jewelry whose main stone was precisely obsidian from Eastern Slovakia. Requests and orders from abroad continued for several years. Uses of obsidian Obsidian has a wide range of uses thanks to its physical and aesthetic properties. Tools: Historically, obsidian was widely used to make various tools and weapons, especially in prehistory. The sharp edges of obsidian were ideal for creating: Arrowheads and spearheads: Due to its sharpness and hardness, obsidian was an ideal material for arrowheads and spearheads. Knives and scrapers: It was used to produce essential cutting tools for the daily life of prehistoric man. Jewelry and decorative objects: Thanks to its luster and aesthetic qualities, Slovak obsidian is a highly prized material for making jewelry and decorative objects: Necklaces, bracelets, and rings: Obsidian is often used in jewelry to create various types of ornaments. Amulets and talismans: Due to its beauty and supposed protective properties, obsidian is often made into amulets and talismans. Decorative figurines and artistic objects: Obsidian handicrafts are valued for their aesthetic and artistic qualities. Healing and esotericism: Obsidian is often associated with spiritual and therapeutic practices: Protective properties: Some people believe that obsidian has the ability to ward off negative energies and protect the wearer from psychic attacks. Healing: In alternative medicine, obsidian is used for its supposed ability to promote emotional balance and inner healing. Collecting: Mineralogical collections: Obsidian is very popular among mineral and gemstone collectors who appreciate its unique properties and appearance. Modern medicine: Surgical scalpels: Although less common, some surgical scalpels are made of obsidian because their extremely sharp edges allow for very precise incisions. Sculpture: Sculpture and carving: Artists use obsidian to create detailed sculptures and carvings due to its excellent workability.\u003c\/p\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028144296261,"sku":"XO003","price":410.44,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/17902_obsidians---brehov--slovakia---100g.jpg?v=1779380839"},{"product_id":"amber-polished-lithuania-1000g-xj010","title":"Amber (polished) – Lithuania – 1000g - XJ010","description":"\u003cul\u003e\n\u003cli\u003eLocation: Lithuania\u003c\/li\u003e\n\u003cli\u003eTotal weight: 1000 g\u003c\/li\u003e\n\u003cli\u003eApproximate weight of individual pieces: 0-0.7g\u003c\/li\u003e\n\u003cli\u003eApproximate size: 0 mm to 15 mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028144361797,"sku":"XJ010","price":355.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/56972_photoroom-008-20260124-212949.jpg?v=1779380842"},{"product_id":"vanadinite-3-5-cm-morocco-1000g-vo5","title":"Vanadinite 3-5 cm – Morocco 1000g - VO5","description":"\u003cul\u003e\n\u003cli\u003eSize: 3 - 5 cm\u003c\/li\u003e\n\u003cli\u003eNumber of pieces: 54\u003c\/li\u003e\n\u003cli\u003eWeight: approx. 1000g\u003c\/li\u003e\n\u003cli\u003eThe photos show the specific lot you will receive.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028144787781,"sku":"VO5","price":161.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/25526_vanadinite-3-5-cm---morocco-1000g.jpg?v=1779380852"},{"product_id":"amber-polished-lithuania-1000g-xj008","title":"Amber (polished) – Lithuania – 1000g - XJ008","description":"\u003cul\u003e\n\u003cli\u003eLocation: Lithuania\u003c\/li\u003e\n\u003cli\u003eTotal weight: 1000 g\u003c\/li\u003e\n\u003cli\u003eApproximate weight of individual pieces: 0-0.1g\u003c\/li\u003e\n\u003cli\u003eApproximate size: from 1 mm to 13 mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028144820549,"sku":"XJ008","price":161.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/56966_amber--polished--lithuania---1000g.jpg?v=1779380855"},{"product_id":"carpathian-obsidians-348g-hedgehog-slovakia-objvel5","title":"Carpathian Obsidians 34.8g (Riccio) – Slovakia - OBJVEL5","description":"\u003cul\u003e\n\u003cli\u003eLocation: Carpathians, Slovakia\u003c\/li\u003e\n\u003cli\u003eTotal Weight: 34.8g\u003c\/li\u003e\n\u003cli\u003eWeight range: 1.4-4.1g\u003c\/li\u003e\n\u003cli\u003eNumber of pieces: 15\u003c\/li\u003e\n\u003cli\u003eDETAILED DESCRIPTION\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSlovakian Obsidian – hedgehog\nThis recently discovered type of Obsidian is among the most beautiful Obsidians in the world. It is distinguished from other Obsidians by its distinctive deep texture, which resembles South Bohemian Moldavite (it is very similar to the Besednice Jezkovna). Its sculpture was formed by rapid cooling, surface cracking, and the subsequent slow action of soil acids at the specific site, just like in the case of Moldavite. The exact location is currently kept secret to protect the area from diggers and potential landscape devastation. We believe that once the precise discovery site is revealed and scientifically examined, interest in this Obsidian with its rare and aesthetic appearance will grow rapidly worldwide – especially due to its significant potential for use in the jewelry industry.\nQuantity and exceptional pieces\nAn estimated 5 kg has been discovered. The average weight of individual pieces is around 3 g. Finds exceeding 10 g are rare. The largest specimen discovered so far weighs an incredible 54 g.\nForgeries and authenticity guarantee\nWe have recorded the presence of forgeries on the market, created by drilling into known Obsidians from Brehov. Forgers attempt to imitate the sculpture, but the result is usually imperfect – drill marks are often visible. A layperson may not recognize a forgery at first glance. Therefore, we recommend being careful about the origin of purchased Obsidian. Our specimens come directly from the finder and we guarantee their authenticity.\nThis distinctly sculpted Obsidian was described in the 2024 book Glassy Wonders.\nEastern Slovakian Obsidian – volcanic glass with exceptional color spectrum\nGeneral\nObsidian is a type of volcanic glass, a rock that is formed as a result of magmatic activity when hot lava comes into rapid contact with a cold environment and then solidifies rapidly. The rock is very rich in silica compounds and is a natural form of glass. It is typically dark in colour, ranging from black, grey or red. It is usually opaque, but its transparency increases as the iron oxide content decreases.\nHistory\nThe occurrence of Obsidian in Slovakia is relatively small compared to other local neovolcanics. Our ancestors used it to make cutting tools as early as the Palaeolithic, but it has been shown that these tools were also used during the Neolithic. In Europe, there are only a limited number of primary occurrences of Obsidian suitable for the production of cutting tools, mainly scrapers, spearheads or knives. It is clear from the results of ongoing research that the importance of Eastern Slovakian Obsidian as a raw material for the production of chipped tools has far exceeded its local significance. Therefore, Eastern Slovakian Obsidian was distributed throughout Central and Eastern Europe and across the Balkans to the Mediterranean.\nA little chemistry\nObsidian is the product of highly acidic lavas of Neogene volcanism. Their origin is closely linked to rhyolite volcanism. Its occurrences form the peripheral parts of larger volcanic bodies, mainly composed of rhyolite. The nests of Obsidian nodules, incorrectly referred to by collectors as mounds, are usually found in rhyolite tuffs, from where it often weathered as a more resistant material, and therefore today its shape and surface (sculpture) often resembles Bohemian Moldavite.\nThe Obsidian of Eastern Slovakia belongs to a group of unaltered acid volcanic glasses with a silica (SiO2) content of about 80%. The higher acidity of the local lavas has caused the Obsidians to have a higher SiO2 content and a lower water content than the world average. This is the reason for their greater durability and suitability for the production of chipped tools. The water content of Obsidian is unusually low. The H2O content varies between 0.19 and 0.31 %. The density varies between 2.3 and 2.4 g\/cm³. Porosity is well below 1 %, and hardness is between 5 and 5.5 on the Mohs scale.\nThe local Obsidian is transparent. Depending on its chemical composition, its colours range from black, to grey, to bluish and greenish, sometimes with silvery highlights. No other Obsidian in the world offers such a colour spectrum!\nInteresting \/ Potential\nAs chance would have it, the occurrence of Obsidian in Slovakia dates back 15,000,000 years ago, around the same time as its Czech \"brother\", Moldavite, to which it is often compared for its appearance, and at a certain distance and under the right light they are indistinguishable from each other. But of course on closer examination the differences are clear and there can be no confusion.\nInterest in Obsidians in general is growing both in Europe and worldwide. The Slovak ones are enhanced by their rare occurrence, limited quantity, unique colour and the aforementioned resemblance to Moldavite. Its current low price makes it an ideal investment stone for the future.\nObsidian is easy to work and polish, and as a raw material it is truly suitable for jewellery and haberdashery purposes. It is also used to make replicas of Palaeolithic cutting tools, stone beads and jewellery. Obsidian can be collected at individual sites in the form of small boulders from 1 to about 20 cm in diameter. However, most of the mounds are between 1 and 5 cm. Their predominant colour is black or blackish grey. The cut stones achieve a high polish and the cut yield is comparable to commercial coloured Chalcedony.\nIt can be used not only in the form of plain cabochon cuts or tables, but since it is transparent, it can also be faceted in the form of rout and step cuts. Faceted stones are very spectacular and surpass in appearance the dark gneisses and morions. Due to its easy workability, it is also a suitable raw material for plastic cutting of small figures, so-called glyptics.\nIn any case, it deserves to be promoted as one of the very interesting materials used since the Stone Age. Although interest in natural glass is growing mainly thanks to tektites, the others are also being mentioned alongside them. The scientific community has organised several conferences dedicated to natural glass research. In 1987, one of them was held under the auspices of Charles University in Prague. For this conference, silver jewellery was produced by the Granat cooperative in Turnov, the dominant stone of which was Obsidian from Eastern Slovakia. Inquiries and orders from abroad continued for several years.\u003c\/p\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028145180997,"sku":"OBJVEL5","price":1911.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/57128_carpathian-obsidians-34-8g--hedgehog--slovakia.jpg?v=1779380867"}],"url":"https:\/\/moldavite.it\/en\/collections\/vendita-allingrosso.oembed?page=2","provider":"Moldavite.it","version":"1.0","type":"link"}
