Topaz[edit]

Topaz is a semiprecious gemstone that occurs as very hard, transparent crystals in a variety of colors. Topaz crystals, such as those found at Topaz Mountain, are naturally amber colored, but become colorless after exposure to sunlight. Topaz forms within cavities of the volcanic rock, Rhyolite, from eruptions that occurred six to seven million years ago during the Tertiary Period. Topaz is embedded in the Rhyolite rock, and also found loose on the slopes and arroyos.

Red beryl[edit]

Red beryl, a rare and valuable mineral found at Topaz Mountain, occurs as small crystals, often attached to other mineral crystals. It is estimated that one red beryl crystal is found for every 150,000 diamonds.[3] Prices for top quality natural red beryl can be as high as $10,000 per carat for faceted stones.[4]

Other minerals[edit]

A variety of other minerals are found at Topaz Mountain including garnet, amethyst, opal, pseudobrookite, and hematite.[5]
