Cartier: A Magnificent Very Light Pink 8.62 Carat Diamond Necklace
the modified marquise mixed cut diamond in a simple white six claw setting, detachable from a pendant mount potentially allowing varied use, both signed Cartier and numbered to the reverse, pendant mount to a trace link chain
necklace length 42.8cm
Provenance: From a private collection, gifted approximately 25 years ago.
The necklace is accompanied by a Colored (sic) Diamond Report from the Gemological Institute of America, GIA, report number 2235473592, dated January 28, 2025, stating the natural diamond weighs 8.62 carat, clarity VVS1, color (sic) very light pink.
Pink diamonds are exceptionally rare. Historically, they have largely been discovered in India, South Africa, Tanzania, and Borneo, amongst other places. Some estimates suggest that as few as 1 in 10,000 gem quality diamonds produced worldwide show any noticeable colour. Of that small number, a similar percentage (approximately 0.01%) have a pink tone. In more recent times (the latter part of the 20th century into the early 21st century) the most prolific producer of pink diamonds in the world was the Argyle mine in Australia. Only 1 in 90,000 diamonds mined there tended to be of gem quality pink colour. Furthermore, Argyle diamonds tend to be in the lower clarity range, unlike this example.
How coloured diamonds are formed varies depending upon the colour. Some diamonds obtain their colour from plastic deformation. This is caused by dislocations in the diamond structure, which happens when the diamond is deep within the Earth, under great pressure, and subject to very high temperatures, when atoms are more mobile. The word plastic indicates that this deformation is permanent. This structural anomaly allows free bonds to react with light, and cause absorption in the blue end of the light spectrum, which can create a brown colour. In pink and red diamonds, the phenomenon is not yet fully understood, and it is possible that the aforementioned plastic deformation occurs in combination with another impurity, or defect, to create these incredibly rare colours.

The necklace is in good condition. It fastens with a bolt ring catch. The diamond is detachable from the reverse of the mount potentially allowing for varied use. By repute, there was originally a sapphire, diamond and pearl drop which formed part of the piece, which has previously been sold. The reverse bears the Cartier signature, stamped '750' and numbered '750624Z'. Once the diamond is detached from the chain the reverse of the mount is also signed Cartier, stamped '750' and numbered '750624'. The pink hue varies under different lighting conditions making it more visible at certain angles, possibly due to the strong orange fluorescence. Gross weight 7.6 grams. CR made 07.02.25.
