A lovely French garland-style pendant/brooch in platinum and set with diamonds. The garland style, popularized by Cartier, heavily borrowed Louis XVI motifs such as bows, ribbons and laurel wreaths—all seen in this example. When worked in platinum, the designs take on a delicate appearance and allow the diamonds to shine. 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.
