This gemstone swirl pendant is handcrafted from 14K/20 gold filled wire and a citrine with a great orangey color. Citrine is a birthstone for November. 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 gemstone pendants are handmade one-at-a-time, so while similar, they are not identical. 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 1/2" 15mm x 38mm 6mm bail
