This tiffany stone pendant is handcrafted from 14K/20 gold filled wire and a Tiffany Stone cabochon (cab) from Utah. This is another unusual piece of tiffany stone. I love the pink color and the black markings. 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 is a really pretty pink. 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 7/8" x 2 3/8" 21mm x 59mm 8mm bail
