Red beryl formation began in the Thomas Range of Utah with the eruption of a topaz rhyolite lava from volcanic vents. As the lava began to cool, shrinkage cracks formed, creating pathways for high-temperature gases rich in beryllium to escape. Oxidized surface water also began seeping into these cracks and mixed with the rising beryllium gases. The gases reacted with the surface water, silica, alkali feldspar, and iron manganese oxides from the lava to form red beryl crystals.  Red beryl probably grew at temperatures between 300 to 650 degrees Celsius. The crystals in the Thomas Range are associated with topaz, bixbyite, garnet, pseudobrookite, or hematite.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eReference: Utah Geological Survey, Survey Notes, v. 34 no. 3, September 2002, Author: Carl Ege\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eDimensions: 7 x 6 x 4 mm.\u003c\/p\u003e","brand":"Roc Doc Minerals","offers":[{"title":"Default Title","offer_id":41495207378990,"sku":"PAL-VAL1290-RB5","price":550.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0585\/8417\/0542\/files\/2025-07-1116-51-44_B_R8_S4.jpg?v=1755354041"},{"product_id":"garnet-var-chromian-grossular-with-vesuvianite","title":"Garnet (var.

Red beryl formation began in the Thomas Range of Utah with the eruption of a topaz rhyolite lava from volcanic vents. As the lava started to cool, shrinkage cracks formed, creating pathways for high-temperature gases rich in beryllium to escape. Oxidized surface water also began seeping into these cracks and mixed with the rising beryllium gases. The gases reacted with the surface water, silica, alkali feldspar, and iron manganese oxides from the lava to form red beryl crystals.  Red beryl probably grew at temperatures between 300 to 650 degrees Celsius. The crystals in the Thomas Range are associated with topaz, bixbyite, garnet, pseudobrookite, or hematite.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eReference: Utah Geological Survey, Survey Notes, v. 34 no. 3, September 2002, Author: Carl Ege\u003c\/p\u003e","brand":"Roc Doc Minerals","offers":[{"title":"Default Title","offer_id":41612360613934,"sku":"2-25070901","price":550.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0585\/8417\/0542\/files\/PAL-VAL1304-RB4_7.jpg?v=1762450314"},{"product_id":"brochantite-1","title":"Brochantite","description":"\u003cp\u003eBrochantite, Kabolela Mine, Katanga, DRC CHOICE!\u003c\/p\u003e\n\u003cp\u003eA breathtakingly exquisite presentation of radiating lustrous tufts of electric green acicular Brochantite crystals on a contrasting brown gossan matrix, which makes for a striking mineral specimen.  This is an absolutely stunning specimen sourced from a fairly obscure Copper mine in the Congo and acquired from a Congo dealer many years ago. \u003c\/p\u003e\n\u003cp\u003eDimensions: 75 x 50 x 40 mm.
