Product Description

For sale is a tachylite specimen from Yetman, NSW. Tachylite, is classified as a low silica obsidian, rather uncommon, especially in display pieces. George’s Smiths Mineralogy of New South Wales, (first published 1926) mentions this tachylite location in his book. Tachylite is a form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. The appearance is very enamel like. The really unusual thing about this is that this is a low silica obsidian, which seems like a contradiction in terms.  This is a particularly large size piece and for a mineral that is usually described as being black in color this is attractive. Interesting and rare!
