Cruzeiro has produced what surely are the most saturated, fanciest color bicolor tourmaline gems, over the years. This is from an old collection, and was mined and cut in the 1990's. It is a superbly cut modified cushion with an art cut on the bottom. The cutting is high quality, and the luster is absolutely top tier. From the collection of former Pro football player, gem collector, entrepreneur, and mineral collector, Ron Gladnick. Joe Budd photos.
