This outstanding unique vintage platinum star burst style brooch displays 4mm cultured pearls with a 6mm cultured pearl at the center. With the pearls are three antique old mine cut diamonds, each approximately 0.50 cts. Diamond color ranges from G-I and the clarity ranges from VVS1 - VS1, approximately 1.50 TCW.
This stunning brooch is a bit of an anomaly. The original mine cut diamonds are from the attached antique yellow gold bar pin, and Cartier used the diamonds and made a bespoke brooch for the client, copies of the original provenance, paperwork and renderings from Cartier attached, in 1957. The brooch is finished with a custom made box from Cartier, embossed and dated on the cover, which is fitted for both the new and original brooches. The brooch was created in London, at Bond Street
Marks: Unmarked, tested as platinum and 18K.
Dimensions: 1 1/8" long x 1 1/8" wide
Weight: 4.0 Gross dwt-Platinum and 18k Brooch; 2.1 Gross dwt-18K Bar Pin Setting
Condition: Good estate condition. The 18K bar pin setting had the stones removed and is engraved.
Please note: Addressing the fact that the brooch is unmarked, Cartier made the brooch - it is a custom, bespoke piece, using the client's diamonds - and while it was made by Cartier, it was not retailed by Cartier.
Provenience: Please see the attached copies of paperwork for the provenance.
