In the world of diamonds, the valuation criteria revolve around the four 'C's of carat, colour, clarity and cut. Few diamonds on the market today fulfil all of these criteria to a high standard, and an immense stone of 30.11 carats, a delicate fancy blue grey colour, of VVS clarity and a beautifully refractive cushion-shape is certainly within the echelons of important gemstones. Moreover, even fewer stones have the rarest fifth characteristic of outright charm, a captivating quality present in particularly special gems, aided in this stone by its extraordinary size and enchantingly ice-like colour. This magical diamond is one which could have been inspiration to F Scott Fitzgerald: not only is it almost a Diamond as Big as the Ritz, but also worthy of the title The Ice Palace.
