These earrings are made with deep violet Holly Blue chalcedony that is completely natural (not dyed). This material came from a mine in the U.S. that has been closed for years. Besides the beautiful color they have no visible flaws or inclusions which are common in chalcedony.
They are constructed with solid 18k gold and have a fan like design that mirrors the shape of the stones. Each earring is approximately 1/2” wide and 11/16″ tall (to the top of the ring that attaches to the ear wire).
