Christina’s daughter auctioned off the necklace through Christie’s in 2008 after her mother passed away. “We are always on the lookout for provenance pieces and historical jewelry,” says Rau, who has bought and sold other important and famous pieces. “It was amazing how it came to us.

He continues: “The pendant is a 38-carat Golconda diamond, which is the purest of all diamonds, possessing a level of clarity, purity and transparency unmatched by any other stone. They are universally recognized as the finest diamonds in the world.

“The central diamond is pear-shaped. It is certified by the Gemological Institute of America (GIA) as both D-color and Type IIa,r, making this gem two shades whiter than the whitest D-color diamond. It also boasts VVS1 clarity, which means its remarkable color is virtually free of any imperfections.

It is hallmarked with French hallmarks for platinum and 18-carat white gold and a maker’s mark for Jacques Timey.
