I call this piece the Ginko leaf. Weight is 19.55 carats and measurements are 8cm x 6cm x 5cm. This fire agate free form cabochon came to me via trade. The mine owner, miner and lapidary artist all the same person. I traded an exquisite aquamarine carved into an octopus. Carved by Ronald Stevens. Aquamarine procured by myself in Pakistan at the mine.
