This whopper was cut by none other than our own Charles Covill of Austin, Texas. It is 42.37ct of pure Mason County natural blue topaz. The gem is a double star Lone Star cut. Charles Covill is famous in our tiny world of gem faceting. He has designed and published hundreds of faceting diagrams, which are the patterns we cutters use to create gems. He has been a member of Texas Faceters' Guild for many years, and has taught many folks to facet gems. He is a living treasure to the gem faceting community.
