What makes pink diamonds special and where do they come from? Most are dug from a single mine in Australia … which just closed – no wonder celebs from Blake Lively to Lady Eliza Spencer are fans

Few gemstones are as lustrous and uniquely saturated as the pink diamond. A wonder of nature, pink diamonds were first discovered in India during the early 17th century in the legendary Kollur mine, one of the largest and most productive diamond mines on the Indian subcontinent during the 16th to mid-19th centuries. A French merchant and adventurer called Jean-Baptiste Tavernier was the first to reference pink diamonds, describing in his travel notes a large pink rough diamond of over 200 carats, shown to him by Moghuls in the Kingdom of Golconda in 1642. This diamond, named The Grand Table, was valued at 600,000 rupees at the time, and is still considered to have been the largest pink diamond found to date. Since then, pink diamonds have soared in popularity, and, as a result, have also been mined in South Africa, Brazil, Canada, Tanzania, Russia and Australia. More than 80 per cent of the world’s pink diamonds originated from the Argyle mine in the Kimberley region of Western Australia up to its closure in 2020, with around 0.1 per cent of the mine’s 20 million carat annual output classified as pink diamonds. Outside the box: colourful gems to wear in an alternative engagement ring “Natural pink diamonds are found in a variety of different shades from soft pinks, to purplish-pinks, to violets and even extremely rare red diamonds,” explains Sophia Hirsh, managing director of British jeweller Hirsh London. Founded by her parents-in-law Anthony and Diane in 1980, Hirsh is one of many contemporary brands propelling the pink diamond into exciting new territory. “We love creating jewellery with these incredible gems as they are so complimentary to any skin tone, however, what we love most about pink diamonds is that they are a mystery,” says Hirsh. “Geologists still do not know exactly what makes them pink, although the most accepted theory is that they are formed by geological shifts as opposed to other colour diamonds which are formed by trace elements being introduced during the crystallisation process. This makes them much more of a natural phenomenon than blue or yellow diamonds. Due to the rarity of natural pink diamonds, they are great investment pieces as well as being beautiful.” Pink diamonds have featured in the brand’s creations since Hirsh’s husband, Jason, and the firm’s founder Anthony Hirsh visited the Argyle Mine in the 1990s on a gem-sourcing trip. “After this trip, we began introducing handmade jewels featuring natural pink diamonds to the global market,” Hirsh explains. Today, a mix of brooches, rings, pendants and earrings set with pink diamonds are peppered throughout Hirsh’s collections, elevated with precious settings and delicate floral motifs. How high jewellers reimagined classic bridal gems in 2022 At David Morris, white diamonds of various cuts have been used to highlight the unique tint of their pink counterpart – a pairing that has been a signature of the maison since its founding in 1962. Just one example is the brand’s Tetris cuff. Taking over three years to craft, the glittering bangle draws inspiration from Brutalist architecture, resulting in a chunky, complex mesh of white gold studded with square and elongated cushion-cut diamonds, interlaced with a smattering of blossom-pink diamonds. Meanwhile, at Boodles, who specialise in remarkable gemstones, brilliant-cut pink and white diamonds are perfectly matched with platinum and single-mine-origin rose gold in the brand’s Raindance earrings, an homage to sprinkled raindrops glistening in the sun. It’s not just heritage names championing the pink diamond, however. Eva Fehren, a New York-based fine jeweller co-founded by designer Eva Zuckerman and her long-time friend, Ann Gorga in 2011, offers a wide range of pieces set with the rosy stone. On dainty pavé bands, they twinkle in a creamy pinkish-brown hue in emerald and shield-cut forms, while hung from statement charms, the diamond is cut to a striking faceted pear shape. Introducing Lulo Rose – the biggest pink diamond discovered in 300 years Because of their rarity, pink diamonds only make rare appearances on the red carpet. Actress Blake Lively, who married actor Ryan Reynolds in 2012, is an exception. Her engagement ring is a 12-carat oval pink diamond ring designed by jeweller Lorraine Schwartz. In June this year, auction house Sotheby’s unveiled the Eternal Pink, “the most vivid pink diamond ever to come to market”, which achieved a world auction record for a purplish pink diamond, selling for US$34.8 million (HK$272.5 million). Another outstanding stone of recent years was the rare 13.33-carat Lesotho Pink Diamond discovered at the Letseng mine in the African kingdom of Lesotho in February 2019. It was later purchased by diamond specialist Graff for US$8.75 million (HK$68.5 million), breaking the record per carat price for any Letseng diamond. “This is the most vivid pink rough diamond I have ever seen, and it is an exceptionally rare treasure,” said Laurence Graff, founder and chairman of Graff, at the time. “We are renowned for cutting and polishing exceptional diamonds, and I am sure the polished diamond that comes from this rough will be an auspicious addition to our roll-call of famous gems. It is an enormous privilege to own this natural miracle, we may never see anything like it again.” While the Lesotho is no longer in Graff’s ownership, the house continues its legacy of working with exceptional pink diamonds in 2023 with new, elevated design. One such example? A 16.88-carat emerald-cut vivid flawless fancy intense pink diamond ring. A thing of beauty in the most mesmerising hue.
