A new type of chalcedony (figure 1) was recently submitted to GIA’s Carlsbad laboratory by Yianni Melas of Greece. According to Melas, this material originated in Africa (figure 2), although a more precise location has not been made available. The translucent material displayed a vibrant bluish green color and is currently marketed under the trade name “Aquaprase.” Although chalcedony varieties such as chrysoprase and Gem Silica are well known and occur in yellowish green and greenish blue colors, the color of this material was distinctly different from any African chalcedony examined by GIA to date.

Maybe just a fancy new name for an old material but pretty stuff anyway.....Mel

Are they claiming a novel metal salt component to produce the color? Maybe a chrome/copper/nickel blend? Yet a fourth non-ferrous green metal salt?

rocknrob: There was a shop in Portland, don't know if it's still there called Kenny and Zukes who made the absolute best pastrami sandwiches I have ever had. The problem is every restaurant thinks their sandwich is worth $20 now and seldom makes the grade. Nov 12, 2024 9:53:31 GMT -5

rocknrob: So, to end my thread on sandwiches. If you find your sandwich worthy of that price by all means keep going to that restaurant (chewie)
