Coloured brilliance on display in LA
The Natural History Museum in Los Angeles displayes the coloured brilliance. The show lets diamond aficionados discover the science behind the sparklers as its Gem and Mineral Vault becomes home to four of nature’s rarest colourful diamond masterpieces. ‘Diamonds: Rare Brilliance’, which opened to the public on 16 December, is said to be the most expensive collection the museum has ever exhibited. The stars of the show are four exceptional coloured diamonds that have never before been seen in public.
Highlighted by the Juliet Pink, the mesmerising showcase is an extremely rare Fancy Intense Pink oval cut diamond set in a white diamond necklace. Weighing 30.03 carats, it is classified as type IIa (meaning no nitrogen impurities) and has one of the highest ranks in terms of clarity of VVS2.
Equally awe-inspiring is the Argyle Violet diamond, a 2.83-carat Oval cut Fancy Deep Greyish Bluish Violet wonder that resides in a ring encircled by a wreath of pink diamonds. Among the rarest diamonds ever found, this is the largest violet diamond unearthed from Australia’s Argyle diamond mine, polished from an extraordinary 9.17-carat rough diamond. Interestingly, the diamond belongs to its own colour category, Violet, which is different from diamonds that are classified as blue or purple.
The fluorescence-exhibiting Rainbow Necklace comprises a vibrant array of 88 natural coloured pink (orange-pink and purple-pink), brown-orange, green-yellow and the extremely rare blue-grey diamonds that range in size from 0.40 to 0.80 carats. The diamonds’ fluorescence is caused by the presence of nitrogen, hydrogen and nickel impurities, which the exhibitors plan to show off under UV light for better viewing.
Rounding out the display is the Victorian Orchid, set in a ring surrounded by white diamonds. The 1.64-carat Fancy Vivid Purple cushion cut diamond with an SI2 clarity grade, and is a different colour grade than the violet or pink diamonds. It is worth noting that purple diamonds are among the rarest, especially when larger than a few carats. They are historically thought to come from Russia, with newer finds from the Argyle mines in Australia.
