This sodalite pendant is handcrafted from 14K/20 gold filled wire and a sodalite cabochon (cab). This one is a uniformly colored, dark navy blue. It can almost look black, but held up to a light it is translucent and almost a cobalt blue. 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 5/8" x 2" 16mm x 52mm 6mm bail
