Few gemstones capture the imagination quite like the pink diamond, which is one of the rarest and most sought-after treasures on Earth. Formed deep within under the Earth’s surface through a unique process known as plastic deformation, each pink diamond owes its mesmerising hue to extraordinary geological forces that twist and distort its crystal structure, creating a beauty unlike any other.

A pink and white diamond crossover ring, available at the Jewellery, Silver & Watches Sale on 20th November.

With the closure of the legendary Argyle Mine in Western Australia which was once the source of 90% of the world’s pink diamonds, these exquisite gems have become even more sought after. As supply has dwindled, demand has soared, with the value of top-quality pink diamonds increasing by as much as 300% in recent years.

Graded primarily for their colour intensity, pink diamonds range from delicate blush tones to vivid, saturated pinks, with each shade expressing its own character and charm. Beyond their undeniable rarity, they are also rich in symbolism, representing romance, individuality, and strength.

Pink diamonds mostly symbolise femininity, romance and love, however they can also symbolise strength, confidence and individuality. They are sought-after by celebrities and jewellery connoisseurs and have been seen on the likes of Margot Robbie, Blake Lively and Victoria Beckham.

As well as celebrities bringing these rare gems into the limelight, there are some incredible examples which have captured imaginations in recent years, such as the Pink Star weighing 59.60ct and which holds the world record for the most expensive gemstone sold at auction when it achieved $71.2 million in Hong Kong in 2017. There is also the legendary Graff Pink which weighed an enormous 24.78ct and was acquired by Laurence Graff for $46 million in 2010. Graff has become synonymous with the best of the best in jewellery featuring pink diamonds, and has promoted their rarity, reporting that many of the pieces they have included in their designs are once-in-a-lifetime discoveries.

These headline sales, celebrity endorsement and the reduction in supply have provided the perfect storm for pink diamonds at auction, with prices rising fast. This exceptional pink diamond ring which is on offer at the present auction embodies all of the qualities which makes these gems so extraordinary, rarity, beauty and timeless appeal.
