Aquaprase Necklace and earrings

This stone is a recent find from Africa. The stones looks like a walk on the beach.
A new type of chalcedony was recently submitted to GIA’s Carlsbad laboratory by Yianni Melas of Greece. According to Melas, this material originated in Africa, 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.”
