shirley temple blue diamond

The jewellery auction season is upon us and this year Sotheby’s and Christie’s are going head to head with some of the most magnificent stones seen on the market for some time. I have previously written about the high demand for investment grade spectacular gemstones and the pieces on offer are sure to whet the appetite of collectors. Each of the auction houses is presenting a stunning array of jewels, but for me the most special ones are the large coloured diamonds and precious stones.
