Beautiful Topaz. Top grade stone at a fraction of the price. Natural stone but heated and irradiated to get its color as all Blue Topaz are. This is an industry accepted practice that gives all Blue Topaz their color. For Proxibid bidders, shipping is a flat rate of $6, no matter how many lots won. For Live Auctioneers bidders, shipping will be calculated automatically by Live Shipping and all winnings will be combined into a single package for one low rate.
