Christie’s Hong Kong has two unique pieces coming up in their upcoming Magnificent Jewels auction on May 30. One of the pieces has a storied place in diamond history.
The item in question is the 25.27 carat Jonker No. 5, which will be up for sale for between $2.2 million and $3.6 million. The Type IIa stone is D color, VVS2 clarity and rectangular in cut.
The Jonker No. 5 is part of a legendary collection of diamonds that came from the famous 726 carat piece of rough discovered by Jacob Jonker in South Africa in 1934, which was at the time, the fourth largest gem quality diamond to be uncovered.
The Diamond Corporation, owned by Sir Ernest Oppenheimer, subsequently bought the rough, which was then purchased by Harry Winston Inc. in 1935. Harry Winston allowed the diamond to be displayed during the Silver Jubilee Celebrations of the Coronation of King George V and Queen Mary in London as well as at the Museum of Natural History in New York, according to Ian Balfour’s “Famous Diamonds.”
Harry Winston chose Lazare Kaplan to cleave and cut the Jonker, and the company examined it for months before the diamond took the final form of 13 polished pieces, ranging in weight from 3.53 carats to 142.90 carats for the largest faceted stone, though this would eventually be reduced to 125.35 carats to give it a greater brilliance.
The second interesting item for sale at the May auction event is the “Palmette” necklace, created by renowned designer Edmond Chin for the House of Boghossian.
The piece features 11 perfectly matched, not oiled, rectangular cut emeralds that range in weight from approximately 3.00 carats to 12.34 carats. The emeralds are surrounded by circular cut emeralds to create a repeating palmette motif with white diamonds of various cuts used in a decorative design.
