About the Cover

Texas topaz, the state’s official gemstone, is valued for its natural blue color. Discovered in 1904, the 925 ct crystal on the cover was formerly displayed in the state capitol building and is now part of the Hamman Gem and Mineral Gallery at the University of Texas at Austin. The 13.8 ct round topaz has a Lone Star cut, faceted to display the five-point star of the state flag. Courtesy of Cub Root (Form to Feeling, Austin, Texas). Photos by Blanca Espinoza.

Printing is by L+L Printers, Carlsbad, CA.
