Pink diamonds

We were given privileged access to the most exclusive diamond sale in the world to discover how these gems are sold to just a discerning few.

A 15.38ct pink diamond ring led the way to a record-breaking total at Sotheby’s Magnificent Jewels and Noble Jewels spring sale.

An intensely coloured 15.38ct Fancy Vivid pink diamond with a stratospheric price tag is the star lot at Sotheby’s Geneva next month.

Our favourite pink diamond jewellery for Valentine's Day celebrates the heart-stopping beauty of this rare gemstone.

Diamonds come from deep inside the earth, where high temperatures and high pressure naturally exist. Most were formed from carbon millions of years ago, which has been in the earth’s mantle since its origins. Some diamonds, however, are made from carbon that comes from the bodies and shells of prehistoric micro-organisms. Their main deposits consist of diamondiferous pipes, or tubes of mineral-rich volcanic rock. These rise to the surface from their primary deposits through volcanic activity in magma or molten rock, which pushes the kimberlite, a volcanic diamond-bearing rock, upwards.

Their elusive nature and stratospheric prices make pink diamonds the most portable form of wealth on our planet. Find out why here.

Dwindling supplies from the Argyle Mine in Australia make pink diamond engagement rings an extremely rare, expensive and desirable choice.
