Jewellery auction of 300 pieces has pre-sale estimate of £43.5m.
Christie’s in Hong Kong has announced a spring time auction of what it describes as extraordinary and magnificent jewels, due to take place on May 31.
The sale, which will take place at the Hong Kong Convention & Exhibition Centre, has already set pre-sale estimates at more than HK$550 million (£43.5m). The auction will offer collectors the chance to bid on almost 300 pieces of jewellery, including rare diamonds, fine coloured gemstones and exceptional jadeite.
Leading the sale is The Imperial Cushions, a pair of spectacular earring (pictured) featuring the world’s rarest diamonds from the legendary Golconda mines in south-central India. The ear-pendants are set with D colour, potentially flawless Golconda Type IIa diamonds. The Imperial Cushions have an estimated sale price of HK$55 million – 75 million (£4.3m – £6m).
The occurrence of such a pair of Golconda gemstones is described as a "natural marvel." At 23.49 and 23.11 carats each, this pair of cushion-cuts is of exceptional calibre – matching in size, cut and shape.
The Christies’ sale will also include a pair of heart-shaped diamond earrings of 13.09 and 12.86 carats respectively, again Type II, D in colour with internally flawless clarity.
Type IIa diamonds are the most chemically pure form of diamond lacking in nitrogen which therefore yield exceptional optical transparency. Thus, the Type II diamond has been being sought-after by many collectors for years.
In its spring sale, Chrisites will also exhibit for sale a range of important sapphires from top sapphire producing regions including Kashmir and Burma. Of note is a pair of 14.84ct and 13.37ct cushions-shaped Kashmir sapphires and diamond earrings, estimated to sell at HK$20.5m (£1.6m)
Among the ruby highlights is a pair of 5.23 and 5.13 carats oval-shaped Burmese ruby and diamond earrings. Without any heat treatment, the ruby earrings are said to possess the most desirable "pigeon’s blood red" colour.
Another lot of note is a suspending carved jadeite disc necklace. This carved jadeite disc is a brilliant emerald green colour with high translucency, depicting two dragons flying amidst clouds, representing the rebus "may your son have a brilliant future and be blessed with success."
