Blue topaz earrings are made with the unique Texas-mined topaz. The gemstones are in the Official Gemstone Cut of Texas: Lone Star Cut which is deeper and has more facets, thus giving the gemstone much more sparkle. While natural, Texas-mined topaz ranges in color from ice white to sky blue, Sandy uses the bluer ones. Your jewelry will truly be one of a kind. Note: Inquire for larger sizes.
