#285 Natural Imperial Topaz7/8" tall. Most topaz is formed in pegmatite rock deposits, which when weathered release topaz and other gems into alluvial deposits. Brazil is the largest producer of fine gem quality Topaz, specifically in the state of Minas Gerias. The imperial version of topaz was discovered there in the town of Ouro Preto in 1735. The little town of Ouro Preto in the state of Minas Gerais, Brazil, is the only locality in which commercially significant deposits of precious topaz are found. No other locality, no other country produces this Imperial version of Topaz. This Crystal measures nearly 2". The color is choice.*
