Record sale of a magnificent pigeon's blood ruby and diamond necklace

A magnificent Burmese Pigeon’s Blood ruby necklace was sold for a total price (including buyers premium) of more than US$ 13 million at the Christie’s Magnificent Jewels auction on 2 June 2015 in Hong Kong. The achieved price makes it the most expensive ruby necklace ever sold at an auction.

The outstanding necklace comprises of 48 unheated Burmese Pigeon’s Blood rubies from Mogok and Mong Hsu (majority from Mogok including the 7.02 ct ruby). All rubies are certified by GRS (and 2 other laboratories) with sizes ranging from 1.09 up to 7.02 carats with a total ruby weight of approximately 120 carats (48 GRS reports, as published in the catalogue).

The detailed break-down of the ruby sizes is as follows:

> 1ct > 2ct > 3ct > 4ct > 4ct > 6ct
11 pcs. 20 pcs. 12 pcs. 2 pcs. 2 pcs. 1 pc.

By allocating US$ 2 million towards the cost for the mounting including the diamonds, the paid carat prices (US$) per size have been calculated by us as follows (estimation, based on GRS market research opinion):

> 1ct > 2ct > 3ct > 4ct > 5ct > 6ct
15,000/ct 25,000/ct 40,000/ct 200,000/ct 300,000/ct 500,000/ct
