This tiffany stone pendant is handcrafted from 14K/20 gold filled wire and a Tiffany Stone cabochon (cab) from Utah. This is definitely one of the most unusual pieces of tiffany stone you are going to see. Just a wonderfully detailed pattern! 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 one has fantastic colors and patterns. You won’t find many like this one! 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 3/4" 29mm x 71mm 8mm bail
