The biggest jewellery sales of 2015

2015 saw a few record-breaking sales in the world of high-end jewellery with auction houses Sotheby’s and Christie’s sharing details on the most striking stones that were purchased at auctions. Sapphires, striking red rubies, and pink diamonds were the gemstones that made headlines the previous year and there were some truly unique finds that exhibited exceptional qualities and were promptly picked up by connoisseurs and collectors. In total, sales of precious jewels came to $214 million and there were quite a few that broke records in terms of size, clarity and brilliance.

The Blue Moon of Josephine


Undoubtedly, the most famous blue diamond of 2015, the 13.02-carat stone was sold to a Hong Kong billionaire for $48,468,158 by Sotheby’s. He reportedly bought it for his 7-yearold daughter and named it after her. This price is by far the largest anyone has ever paid for a diamond of any colour and size.
