This gemstone swirl pendant is handcrafted from 14K/20 gold filled wire and a peridot with a great apple green color. Peridot is the birthstone for August. I know a lot of August babies (including myself) think they don’t like the olive color of peridot - but this apple green peridot will change your mind. It is just lovely! 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 1/4" 15mm x 31mm 3mm bail
