Libyan Desert Glass is almost pure silica. It lies in the corridors between dunes in the southwestern Great Sand Sea of western Egypt, near the Libyan border, scattered over an area of roughly 2,500 to 6,000 square kilometres.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eFor decades scientists argued about how it formed. Ideas ranged from lunar volcanoes to a meteor exploding in the air. In 2019, researchers found zircon grains in the glass that had once been reidite, a mineral that forms only under shock pressures of about 30 gigapascals. That same year, shocked quartz turned up in the local bedrock. Together these point to a real meteorite impact. No crater has ever been found, and it may have eroded away or be hidden under the dunes.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eAn Egyptian Desert Survey expedition led by Patrick Clayton found the glass on 29 December 1932, and Clayton and Leonard Spencer of the British Museum described it in 1934. People had found it long before that. The yellow scarab at the centre of a pectoral from Tutankhamun's tomb is carved from Libyan Desert Glass.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eAbout 1,400 tonnes of the glass are estimated to survive. Pieces are typically strongly wind-eroded from millions of years in the open desert. This one weighs 175 g.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eIn crystal traditions, Libyan Desert Glass is associated with transformation and manifestation.\u003c\/p\u003e\n\u003cp class=\"p1\" data-mce-fragment=\"1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eChemical Composition\u003c\/b\u003e: SiO2\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp class=\"p1\" data-mce-fragment=\"1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eChakra\u003c\/b\u003e: Third Eye \u0026amp; Solar Plexus \u003c\/p\u003e\n\u003cp class=\"p1\" data-mce-fragment=\"1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eSize\u003c\/b\u003e: 7cm x 6.5cm x 5.5cm \u003cbr\u003e\u003cb data-mce-fragment=\"1\"\u003eWeight\u003c\/b\u003e: 175g\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp class=\"p1\" data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eQuantity\u003c\/strong\u003e: 1pc\u003c\/p\u003e\n\u003cp class=\"p1\" data-mce-fragment=\"1\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003ci data-mce-fragment=\"1\"\u003eWith this product, you will get the actual stone in the photograph.
