How can I, a cutter that has scaled such tourmaline pinnacles, call a smaller standard round brilliant with a reasonably common color and tone level great, because it is. Size does matter with tourmaline, though certainly not as much as with corundum.(ruby and sapphire) , but hues like this round has, can only be dreamed of in larger gemstones in my collection. If I was ever to design a color wheel from tourmaline in the collection, I would use droplets of color with only one or two additions to get it as broad based as possible. The posted beauty has all the great properties that set a fine color off. It weighs .65 carats.
