It is among the most recently discovered sources of amber and has gained popularity in recent decades, particularly for its rare blue and green varieties.\nOrigin\nIndonesian amber primarily originates from the islands of Sumatra, Borneo (Kalimantan), and Sulawesi. The most famous deposits are found in the Aceh province, Sumatra. Geologically, this amber dates back to the Miocene epoch, approximately 20–23 million years ago.\nColors and Optical Properties\nIndonesian amber comes in a wide range of colors. The most prized is blue amber, which fluoresces with a blue glow under UV light or in direct sunlight. This effect is caused by the presence of aromatic hydrocarbons. However, the blue color does not always manifest under all conditions—it is best observed under UV light or in direct sunlight. Green amber is rarer and owes its color to trace elements and natural oxidation. Red and brown varieties are more common and resemble Baltic amber in appearance. Golden amber is translucent and exhibits honey-yellow hues.\nComposition and Physical Properties\nIndonesian amber has a hardness of approximately 2–2.5 on the Mohs scale, making it relatively soft and easily scratched. Its density ranges between 1.05 and 1.10 g\/cm³, which is why it often floats in salt water. Chemically, it contains less succinic acid compared to Baltic amber, distinguishing it.\nInclusions\nUnlike Dominican or Burmese amber, Indonesian amber very rarely contains insect inclusions. It more often contains plant remains such as leaf fragments, needles, or resin bubbles. Air bubbles can produce interesting optical effects. Microorganisms occasionally appear. The geological conditions and age of this amber likely did not allow for the preservation of large quantities of animal inclusions.\nExtraction\nIndonesian amber is extracted by hand in tropical jungles, often within coal sediments. After extraction, it is cut, polished, and sold in both raw and processed gemstone forms.\nIndonesian amber is popular in Asia, Europe, and the United States. Its price depends on color, transparency, and the presence of inclusions. Blue amber is the rarest and most expensive. Green amber is also rare but more accessible. Red and golden amber are among the more common and less expensive types. It is primarily used for making necklaces, bracelets, rings, and decorative items, and is often paired with silver or other precious metals.\nAuthenticity\nSeveral methods can verify the authenticity of Indonesian amber. In the salt water test, amber floats in salt water with a density greater than 1.1 g\/cm³. Under UV light, blue amber fluoresces blue, and green amber often fluoresces yellow. When heated, real amber emits a characteristic resinous odor. To the touch, it feels warm and non-sticky, unlike plastic imitations, which tend to be cold and excessively light.\nMany fakes exist on the market. Plastic imitations or pressed amber—made by compressing small fragments—are commonly sold. This type has a lower value than natural amber. Another common substitute is copal, a younger natural resin that is only 1–5 million years old.\u003c\/p\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028100583749,"sku":"JNI49","price":165.47,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/43136_photoroom-000-20250424-092352.jpg?v=1779380120"},{"product_id":"raw-amber-sumatra-indonesia-jni48","title":"Raw amber – Sumatra, Indonesia - JNI48","description":"\u003cul\u003e\n\u003cli\u003eLocation: Sumatra, Indonesia\u003c\/li\u003e\n\u003cli\u003eWeight: 28g\u003c\/li\u003e\n\u003cli\u003eSize: 6.8 x 4.1 x 2.6 cm\u003c\/li\u003e\n\u003cli\u003eUV active\u003c\/li\u003e\n\u003cli\u003eDETAILED DESCRIPTION\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIndonesian amber stands out for its unique color range, geological age, and the rarity of its inclusions.

It is mainly used for making necklaces, bracelets, rings, and decorative objects, and is often paired with silver or other precious metals.\nAuthenticity\nThere are several ways to verify the authenticity of Indonesian amber. In the salt test, amber floats in saltwater with a density greater than 1.1 g\/cm³. Under UV light, blue amber fluoresces blue, and green amber often fluoresces yellow. When heated, real amber emits a typical resinous smell.

It is among the more recently discovered sources of amber and has gained popularity in recent decades, particularly for its rare blue and green varieties.\nOrigin\nIndonesian amber primarily originates from the islands of Sumatra, Borneo (Kalimantan), and Sulawesi. The most famous deposits are found in the Aceh province of Sumatra. Geologically, this amber dates back to the Miocene epoch, approximately 20–23 million years ago.\nColors and Optical Properties\nIndonesian amber comes in a wide range of colors. The most prized is blue amber, which fluoresces with a blue glow under UV light or direct sunlight. This effect is caused by the presence of aromatic hydrocarbons. However, the blue color does not always manifest under all conditions — it is best observed under UV light or direct sunlight. Green amber is rarer and owes its color to trace elements and natural oxidation. Red and brown varieties are more common and resemble Baltic amber in appearance. Golden amber is translucent and displays honey-yellow hues.\nComposition and Physical Properties\nIndonesian amber has a hardness of about 2–2.5 on the Mohs scale, making it relatively soft and easily scratched. Its density ranges from 1.05 to 1.10 g\/cm³, which is why it often floats in salt water. Chemically, it contains less succinic acid than Baltic amber, distinguishing it from the latter.\nInclusions\nUnlike Dominican or Burmese amber, Indonesian amber very rarely contains insect inclusions. It more often contains plant remains such as leaf fragments, needles, or resin bubbles. Air bubbles can produce interesting optical effects. Microorganisms occasionally appear. The geological conditions and age of this amber likely did not allow for the preservation of large quantities of animal inclusions.\nExtraction\nIndonesian amber is extracted by hand in tropical jungles, often from within coal sediments. After extraction, it is cut, polished, and sold both in raw form and as a processed gemstone.\nIndonesian amber is popular in Asia, Europe, and the United States. Its price depends on its color, transparency, and the presence of inclusions. Blue amber is the rarest and most expensive. Green amber is also rare but more accessible. Red and golden amber are among the most common and least expensive types. It is mainly used for making necklaces, bracelets, rings, and decorative objects, and is often paired with silver or other precious metals.\nAuthenticity\nThere are several ways to verify the authenticity of Indonesian amber. In the salt test, amber floats in saltwater with a density greater than 1.1 g\/cm³. Under UV light, blue amber fluoresces blue, and green amber often fluoresces yellow. When heated, real amber emits a characteristic resinous odor.

It has gained global recognition thanks to specific localities and some unique properties that set it apart from the much more common Baltic or Dominican amber.\nProperties and Appearance\nColombian amber can range in color from light yellow to dark brown, with honey and reddish tones. As with other types of amber, it can be found in transparent forms, as well as in specimens with varying degrees of turbidity.\nAge\nColombian amber primarily comes from more recent geological periods (most commonly Miocene-Pliocene, which is approximately 2.6–23 million years old).\nSome Colombian localities also yield so-called copal, a younger form of fossil resin that has not yet reached the age, chemical stability, or degree of polymerization typical of true amber. Unlike amber, which formed tens of millions of years ago (e.g., during the Eocene), copal is usually less than 5 million years old, and often only a few hundred thousand years old.\nCopal can resemble amber at first glance—it is often clear, golden, and lightweight, and can sometimes contain insect or plant inclusions. However, the fundamental difference lies in its physical and chemical properties: copal is softer, less stable, often slightly sticky, and dissolves in organic solvents (e.g., acetone), whereas true amber remains unaffected.\nIn Colombia, copal is mainly extracted in regions such as Huila, Tolima, or El Valle, and is often commercially labeled as \"young amber,\" even though scientifically it is not considered true amber. Therefore, it should always be clearly labeled to avoid confusion with true amber from regions like Santander.\nInclusions\nColombian amber can preserve fossilized remains of various prehistoric insects (e.g., ants, termites, mosquitoes, wasps, beetles), arachnids, and plant material such as fibers, leaf fragments, or pollen grains. Rarer inclusions may include small pieces of lichens or mosses, providing insight into the rich vegetation and tropical conditions of the era.\u003c\/p\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028103893317,"sku":"JN190","price":63.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/40979_photoroom-037-20250407-001841.jpg?v=1779380201"},{"product_id":"raw-young-amber-copal-colombia-jn347","title":"Young raw amber (copal) – Colombia - JN347","description":"\u003cul\u003e\n\u003cli\u003eLocation: Villanueva, Santander, Colombia\u003c\/li\u003e\n\u003cli\u003eWeight: 56g\u003c\/li\u003e\n\u003cli\u003eSize: 7.6 x 4.8 x 4 cm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028104417605,"sku":"JN347","price":54.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/35885-3_photoroom-001-20250227-112842.jpg?v=1779380214"},{"product_id":"raw-young-amber-copal-colombia-jn346","title":"Rough young amber (copal) – Colombia - JN346","description":"\u003cul\u003e\n\u003cli\u003eLocation: Villanueva, Santander, Colombia\u003c\/li\u003e\n\u003cli\u003eWeight: 114g\u003c\/li\u003e\n\u003cli\u003eSize: 9.8 x 5.1 x 4 cm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028104515909,"sku":"JN346","price":180.98,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/35882-3_photoroom-20250227-103450.jpg?v=1779380216"},{"product_id":"raw-amber-sumatra-indonesia-jni50","title":"Raw Amber – Sumatra, Indonesia - JNI50","description":"\u003cul\u003e\n\u003cli\u003eLocation: Sumatra, Indonesia\u003c\/li\u003e\n\u003cli\u003eWeight: 38.3g\u003c\/li\u003e\n\u003cli\u003eSize: 6.6 x 4.1 x 3 cm\u003c\/li\u003e\n\u003cli\u003eUV active\u003c\/li\u003e\n\u003cli\u003eDETAILED DESCRIPTION\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIndonesian amber stands out for its unique color range, geological age, and the rarity of its inclusions. It is among the most recently discovered amber sources and has gained popularity in recent decades, particularly for its rare blue and green varieties.\nOrigin\nIndonesian amber primarily comes from the islands of Sumatra, Borneo (Kalimantan), and Sulawesi. The most famous deposits are found in the Aceh province of Sumatra. Geologically, this amber dates back to the Miocene epoch, approximately 20–23 million years ago.\nColors and Optical Properties\nIndonesian amber comes in a wide range of colors. The most prized is blue amber, which fluoresces with a blue glow under UV light or in direct sunlight. This effect is caused by the presence of aromatic hydrocarbons. However, the blue color does not always appear under all conditions—it is best observed under UV light or in direct sunlight. Green amber is rarer and owes its color to trace elements and natural oxidation. Red and brown varieties are more common and resemble Baltic amber in appearance. Golden amber is translucent and features honey-yellow shades.\nComposition and Physical Properties\nIndonesian amber has a hardness of about 2–2.5 on the Mohs scale, making it relatively soft and easily scratched. Its density ranges from 1.05 to 1.10 g\/cm³, which is why it often floats in salt water. Chemically, it contains less succinic acid than Baltic amber, distinguishing it from the latter.\nInclusions\nUnlike Dominican or Burmese amber, Indonesian amber very rarely contains insect inclusions. It more often contains plant remains such as leaf fragments, needles, or resin bubbles. Air bubbles can produce interesting optical effects. Microorganisms occasionally appear. The geological conditions and age of this amber probably did not allow for the preservation of large quantities of animal inclusions.\nExtraction\nIndonesian amber is extracted by hand in tropical jungles, often within carbonaceous sediments. After extraction, it is cut, polished, and sold both in rough form and as a processed gemstone.\nIndonesian amber is popular in Asia, Europe, and the United States. Its price depends on color, transparency, and the presence of inclusions. Blue amber is the rarest and most expensive. Green amber is also rare but more accessible. Red and golden amber are among the most common and less expensive types. It is primarily used for making necklaces, bracelets, rings, and decorative objects, and is often paired with silver or other precious metals.\nAuthenticity\nThere are several ways to verify the authenticity of Indonesian amber. In the salt test, amber floats in saltwater with a density greater than 1.1 g\/cm³. Under UV light, blue amber fluoresces blue, and green amber often fluoresces yellow. When heated, real amber emits a typical resinous odor. To the touch, it feels warm and not sticky, unlike plastic imitations, which tend to be cold and excessively light.\nMany fakes exist on the market. Plastic imitations or pressed amber—made by compressing small fragments—are commonly sold. This type has a lower value than natural amber. Another common substitute is copal, a younger natural resin that is only 1–5 million years old.\u003c\/p\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028162974021,"sku":"JNI50","price":98.89,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/43139_photoroom-004-20250424-092352.jpg?v=1779381237"},{"product_id":"raw-amber-sumatra-indonesia-jni41","title":"Raw amber – Sumatra, Indonesia - JNI41","description":"\u003cul\u003e\n\u003cli\u003eLocation: Sumatra, Indonesia\u003c\/li\u003e\n\u003cli\u003eWeight: 32g\u003c\/li\u003e\n\u003cli\u003eSize: 6.2 x 3 x 2.6 cm\u003c\/li\u003e\n\u003cli\u003eUV active\u003c\/li\u003e\n\u003cli\u003eDETAILED DESCRIPTION\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIndonesian amber stands out for its unique color range, geological age, and the rarity of its inclusions.
