This rhodonite pendant is handcrafted from 14K/20 gold filled wire and a rhodonite cabochon (cab) from Australia. This is almost pure raspberry sherbert with no black markings and almost no color variations. 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 1/2" x 1 7/8" 15mm x 49mm 6mm bail
