This Edwardian double-bow diamond pin brooch pendant will absolutely take your breath away: As a classic example of Belle Époque jewelry made in the early 20th century, this stunning brooch features a mix of high quality old mine cut and old European cut diamonds set with solid platinum on top of 18K yellow gold. It has a total of 40 old mine cut and old European cut diamonds ( 0.56 ct center diamond and 6.34 ctw total diamonds).

More amazingly, this brooch has two original built-in hoops at the top, which allows the brooch to be used as a pendant! It saves your pain (and guilt!) of brooch-to-pendant conversion:) *To convenience those whoever intends to wear it as a pendant, I added two gold filled jump rings to the built-in hoops and a 18" gold filled chain which can be easily taken on or off. The length of the chain can be customized by request.
