Excellent antique condition, shows minor wear. This piece was formerly a pendant but was fitted with a pin and catch probably sometime around the 1950s. Rear is engraved with previous owner's initials. Has been extensively tested and is guaranteed to be solid 14k gold (apart from pin, hinge, and catch). Old mine cut diamond is irregular in shape but still brilliant and beautiful and is guaranteed to be natural and genuine. Due to the measurements, I am unable to confidently provide carat weight of diamond. Total weight is 4.94 grams. Locket and brooch clasp both function perfectly. Please see photos for measurements in inches.
