Topaz The Mineral Topaz Information And Pictures

Topaz The Mineral Topaz Information And Pictures Topaz is a well-known mineral, occurring in large and beautifully shaped and colored crystals. It naturally occurs in many colors, but rarely in pink, purple, and deep blue. Those colors are formed from lighter-colored stones that undergo irradiation and heat treatment. Topaz from certain localities may also turn pink or colorless upon heating.Topaz is a well-known mineral, occurring in large and beautifully shaped and colored crystals.
