The Gemological Institute of America (GIA) has evaluated more than 30 rare and historically significant jewels ahead of Christie\u2019s Magnificent Jewels auction, taking place on 17 June in New York. Among the most notable is the Marie-Th\u00e9r\u00e8se Pink, a 10.38-carat diamond graded Fancy Purple-Pink by GIA associated with one of history\u2019s most iconic figures, Queen Marie-Antoinette of France, and later, her daughter, Duchess Marie-Th\u00e9r\u00e8se of Angoul\u00eame.<\/p>\n
Estimated by Christie\u2019s at between US$ 3 million and US$ 5 million, the ring stands out for its vibrant purple-pink hue, modified brilliant kite cut, and royal provenance. Likely originating from India, where purple-pink diamonds are seldom unearthed, it was crafted in the mid-1700s. The Marie-Th\u00e9r\u00e8se Pink is believed to have been passed down from Queen Marie-Antoinette to her daughter, Duchess Marie-Th\u00e9r\u00e8se of Angoul\u00eame, and subsequently to her niece, Duchess Marie-Th\u00e9r\u00e8se of Chambord, making this gem unique from both a gemological and historical perspective.<\/p>\n
\u201cGIA evaluated the Marie-Th\u00e9r\u00e8se Pink in advance of the auction, providing a detailed gemmological assessment that confirms the diamond\u2019s colour origin and internal characteristics,\u201d said Tom Moses, GIA\u2019s Executive Vice President and Chief Laboratory and Research Officer. \u201cThrough our evaluations, GIA helps record the properties and history of these notable diamonds.\u201d<\/p>\n
In addition to the Marie-Th\u00e9r\u00e8se Pink, GIA evaluated more than 30 other exceptional jewels to be presented at the auction. One of the items is an unmounted diamond weighing more than 60 carats, notable for its symmetry, internal clarity and overall brilliance. Another highlight is a diamond pendant necklace that features classical European design elements.<\/p>\n
With increased global attention on coloured diamonds and the closure of sources such as the Argyle Mine in Australia, stones like the Marie-Th\u00e9r\u00e8se Pink are physical records of what nature and history have produced, preserved and passed down.<\/p>\n","protected":false},"excerpt":{"rendered":"
