Fancy colour diamonds are taking centre stage at auctions and novel collections despite challenging macroeconomic conditions, thanks to the market’s unwavering demand for top-colour, investment-quality items.

An exceptional purplish-pink diamond is expected to wow audiences at Christie’s upcoming Magnificent Jewels auction in New York scheduled for April 13.

The Fuchsia Rose, a fancy intense purple-pink diamond weighing 8.82 carats valued at US$4 million to US$6 million, will headline an expansive range of fancy colour diamonds, coloured gemstones and finished jewellery to be offered at the sale.

Other highlights are a fancy blue diamond ring of 11.63 carats and a fancy vivid yellow diamond ring of 15.31 carats. 

Sotheby’s meanwhile is expecting a 15.10-carat fancy vivid blue diamond, known in the trade as the De Beers Cullinan Blue, to fetch more than HK$380 million (around US$48 million) in Hong Kong. 

Cut from a historical rough stone discovered in April 2021, the gem has re-emerged as the largest vivid blue diamond ever to appear at auction and the largest internally flawless step-cut vivid blue diamond that the Gemological Institute of America has ever graded. 

The De Beers Cullinan Blue anchors Sotheby’s Hong Kong Luxury Week, and will be offered in a stand-alone, single-lot live auction in late April 2022. Sotheby’s will announce the exact date later.

The Perth Mint for its part is offering a limited-edition coin – the Jewelled Koi – that highlights the exceptional beauty of Australia’s coveted Argyle pink diamonds.

Described as one of The Perth Mint’s most luxurious coins launched to date, the Jewelled Koi is part of the group's Masterpieces Series and is the fifth annual release from a range of diamond-studded coins, namely Jewelled Phoenix, Dragon, Tiger, and Horse coins – all sought after by enthusiasts all over the world.

This is also the first time that a Perth Mint coin features pavé set white diamonds and ultra-rare Argyle Pink Diamonds™. There are only eight of these coins available at AU$262,800 (around US$190,000) each.
