This exquisite sky blue is what a certain Abalone turns when fed dried milk. Unreal, right? It's true. Hoarding this special Abalone shell for years, I am ready to give it up now. At one time I had a handful, but none this big. I no longer have even a handful. Set with a deep-watery, Trillion-Cut Aquamarine. The reverse, Nacre side is a magnificent Petroleum Blue.
