Buyer's premium:

The center old European cut diamond, graded as J/SI1, weighs .48 carat. The diamond hanging from an articulated millegrained knife-edge mounting has the same grading and weighs .35 carat. The smaller diamonds are a mix of antique cushion, rose and Swiss cuts. This piece has two small loops at the top of the back so it can be worn from a fine platinum chain. When worn as a pendant, the 18K gold brooch fitting can be unscrewed and removed entirely. Convertible fittings such as this were difficult to make and always signaled a piece of high quality. The hallmarks allow the pendant/brooch to be definitively dated prior to 1912. Origin: France, ca. 1910. Condition: excellent, all original. Size: 1-11/16” x 1-9/16”. Weight: 10.8 grams. Approximate Total Diamond Weight: 2.15 carats.

Condition: Good
