Verre Libyque en taille diamant
Libyan glass in diamond cut of 46 carats

Libyan glasses (Lybian Glass), increasingly rare and sought-after, cut very well. This one, of 46 carats, is very translucent with some white inclusions of a mineral called stishovite. It is a high-pressure mineral found at sites of major meteorite impacts and in some meteorites. About Libyan glass, scientists now agree that these vitreous blocks are the result of a giant meteorite impact more than 29 million years ago on desert sand that was melted by the blast effect. The measurements are 25 mm in diameter (18 mm from table to tip) for 46 carats. Automatically translated by DeepL. To see the original version, click here.
