Olivier Wagner, Head of Jewellery at Sotheby's Geneva, said, “The sale of the Laguna Blu tops the remarkable performance of our Magnificent Jewels and Noble Jewels sale that saw exceptional coloured gemstones, in particular emeralds and yellow diamonds, punch through their high estimates, in such a spectacular fashion. There is no doubt that high quality high jewellery can still command sky high prices.”
Sotheby’s said that fewer than ten fancy vivid blue diamonds over 10 carats have come to auction anywhere in the world in the past few decades. Blue diamonds, of any kind and any size, are among the rarest coloured diamonds. Any blue diamond qualifying as Fancy Vivid – the brightest hue a diamond can display – over 10 carats are extremely rare.
