• DETAILED DESCRIPTION

Australites – a natural phenomenon of extraordinary origin Australites were formed approximately 790,000 years ago during a massive meteorite impact in what is now Southeast Asia. Molten material was ejected thousands of kilometres to Australia, where it briefly left the Earth's atmosphere. Upon re-entry, it underwent rare secondary melting, cooled in mid-air, and fell to the ground — forming aerodynamically shaped pieces known as "australite buttons." 1. Unique Shape and Appearance Their initial velocity was higher than that of other tektites, allowing them to rise just beyond the atmosphere. Upon re-entry, they underwent a rare process of ablative melting. Under aerodynamic stress, molten material accumulated along the edges of the tektite, forming the distinctive ablative flange — clear evidence of formation during flight. This is known as the ablative phenomenon. Australite buttons typically have the shape of a disc, lens, mushroom, or saucer, and are considered the most aesthetic and perfectly formed natural glasses in the world. Other tektites (e.g. moldavites) do not occur in this shape or quality. 2. A Single World Location These tektites are found exclusively in Central and Southern Australia — specimens shaped like this do not exist anywhere else on Earth. Although the strewn field is large, collector-quality buttons are very rare. 3. Limited and Depleting Resource The richest sites (e.g. the Nullarbor Plain) have been largely depleted over the 20th century. Today, it is increasingly difficult to find new specimens, and collecting is regulated or prohibited in many areas. Heavy fines are imposed for illegal collection or export. Commercial-scale collection can even lead to imprisonment. 4. Excellent Investment Potential Prices for well-preserved specimens continue to rise — especially for symmetrical buttons with flanges. Like moldavites, australites have collectible and investment value, but they are far rarer. Unlike moldavites, which are well-known in Europe, australites are less common, adding significant value to collections. Only a few complete buttons are sold per year, and collectors often bid fiercely — many never reach Europe.
