This November, Christie’s partners with De Beers Group Institute of Diamonds to present Rare Treasures of the Earth, a selling exhibition exploring the origin, rarity and value of exceptional gemstones.

From sensational coloured diamonds from the vault of Christie’s Private Sales to rare crystals and minerals supplied by Dale Rogers Ammonite, highlights of the exhibition include The Cullinan Dream, a 24.18-carat Fancy Intense Blue VS2 rectangular-shaped diamond, a quartz and chalocopyrite from Bulgaria and a set of four Fancy Intense to Vivid Purple cushion and rectangular-shaped diamonds – all available for purchase.

Venture deeper into our King Street galleries, we invite you to uncover the science behind diamonds under the guidance of the experts from De Beers Group Institute of Diamonds – from colour classification to polishing and grading – all while appreciating the multi-faceted brilliance of these gems. We look forward to welcoming you to this exciting exhibition in London, open to all and free entry from 8–12 November.
