Harry Winston’s famous Jonker V diamond to fetch up to $3.6M in auction

Harry Winston’s famous Jonker V diamond is expected to fetch between $2.2 million to $3.6 million, or up to $142,461 per carat, when it goes under Christie’s hammer at the auction house’s Magnificent Jewels sale to be held in Hong Kong in May.

The rectangular-cut, 25.27-carat, D-color, VVS2-clarity gem is one of a collection of 13 polished diamonds cut from the famous 726-carat Jonker rough, unearthed by Jacob Jonker at South Africa’s Elandsfontein mine in 1934.

The famous rough diamond was even inspiration for a movie. Directed by Jacques Tourneur, A Miniature: The Story of the Jonker Diamond told how it had been discovered, sold first to Ernest Oppenheimer, then to Harry Winston and finally cut into over a dozen extraordinary gemstones.

Christie’s Hong Kong auction on May 30 will also feature an emerald-and-diamond necklace created by designer Edmond Chin, which is expected to sell for $3.6 million to $5 million.
