This chunky heart pendant is handcrafted from 14K/20 gold filled wire and a bright red glass heart. 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 these popular 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 1/4" x 2" 31mm x 51mm 9mm bail
