• 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. The molten material was ejected thousands of kilometers to Australia, where it briefly left 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 greater than that of other tektites, allowing them to rise just beyond the atmosphere. Upon re-entry, they underwent a rare ablative melting process. Under aerodynamic stress, molten material accumulated along the edges of the tektite, forming the characteristic ablative flange — clear evidence of formation during flight. This is known as the ablative phenomenon. Australite buttons typically have the shape of a disk, 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 global location These tektites are found exclusively in central and southern Australia — specimens shaped in this way do not exist anywhere else on Earth. Although the strewn field is large, collector-quality buttons are very rare. 3. Limited and diminishing resource The richest sites (e.g., the Nullarbor Plain) were mostly depleted during the 20th century. Today, it is increasingly difficult to find new specimens, and collection is regulated or prohibited in many areas. Heavy fines are imposed for illegal collection or export. Commercial scale collection can even result in 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 much 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 compete fiercely — many never reach Europe.
