This chalcedony pendant is handcrafted from 14K/20 gold filled wire and a chalcedony cabochon (cab). Sometimes I would say that this stone is a cornflower blue. Other times I would say it is a grey-blue. It seems to change a bit with the light, but it is always very calming. 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" x 2 1/2" 25mm x 65mm 9mm bail
