For a gem dealer nothing takes the place of going to the mining areas. The two gems you see pictured are ones we found by going to the right place. The cut stone is one piece of a small lot of 3 pieces we bought many years ago in Brasil. The color is truly amazing and truly a collectible color. The stone is over 10 carats in weight. According to prices seen fairly recently for similar (but not quite as good) gems—it is worth several thousand dollars per-carat. This is a color and size and clarity in Imperial Topaz very seldom seen available for sale
