Large 2" diamond preserves the mysterious wing of this subspecies. This particular butterfly came from a vintage collection of specimens and was not labeled, and after extensive research, I couldn't identify it! It's elusiveness makes it all the more rare, and one of a kind. It is some type of Papilio subspecies, likely native to central Asia or the Philippines. 16" gunmetal chain with lobster clasp closure. Reversible, with black and white patterns on the reverse, for two pendants in one.
