NOT a Catbird charm but sending it in full Catbird packaging because I was inspired by their Give You the Moon charm to find something similar :) Purchased from Etsy - 10mm x 10mm rainbow moonstone, solid gold around the stone, but the jump ring is NOT solid gold. Selling with a gold-PLATED 18" chain with 2" extender. I tried desperately to capture the stone in different light as best as my old phone could! It has that gorgeous blue flash at the top but is more milky and white overall. I'm selling because I found a clearer stone I prefer. The charm was worn once; the included chain is new.
