The Lone Star cut, designed by two native Texans, is a special gemstone cut that reflects a five-pointed star (the Lone Star of Texas).
Topaz comes in all colors; a golden orange-yellow (called "imperial topaz") is considered the most valuable. Topaz is commonly thought of as a sky-blue gem, but a deep blue hue is rare in nature (colorless and light-hued stones are heat-treated to achieve the blue color).
The largest gem topaz deposits are in Brazil and Russia. Other locations include Mexico and the USA (Texas, Colorado, Utah).
