Fantastic topaz thumbnail!: the topaz itself is gem-clear, sharp, and terminated; and it has a very light amber color that adds just a tiny bit more character to an already great specimen. Even better, this Topaz is attached to a terrific feldspar that is so sharp and lustrous that it is a good specimen in and of itself and perfectly balances the topaz for size and basic geometry. This is a killer thumbnail in every way. It was my first-choice pick for sheer style, if not the most expensive rock, from Scott Werschky's thumbnail collection some years ago and I was able to trade it from Scott at that time and sell it to this collector.
