This tiffany stone pendant is handcrafted from 14K/20 gold filled wire and a Tiffany Stone cabochon (cab) from Utah. This stone has wonderful colors and patterns! Tiffany Stone is a rare stone that goes by many names, including bertrandite, beryllium ore, opal fluorite, opalized fluorite, Purple Opal, and Ice Cream Opalite. This cab has fantastic color and pattern. You will not find many pieces of tiffany stone like it. 14K/20 gold filled wire is basically a tube of 14K gold with a jeweler’s wire down the center for flexibility. It wears well, does not tarnish, and has the same allergy reactions (or non-reactions) as 14K gold. Each of my cabochon pendants are "one-of-a-kind" and you are selecting the actual one you will be receiving. The chain is not included, but I do have a selection of chains if you need one. approximately 1 1/8" x 2 1/2" 30mm x 63mm 8mm bail
