Report no. 57534 dated 30 September 2010 from the SSEF Swiss Gemmological Institute stating that the emerald is of Colombian origin, with no indications of clarity enhancement, and an Appendix stating “Natural emeralds from Colombia of this size, color and purity represent a great rarity and the described gemstone is thus a very exceptional treasure”
Jean-Marc Lunel, Head of Christie’s Geneva Jewellery Department said: “Golconda, Muzo, Kashmir: these are magic words to any gem connoisseur.” Adding to the historic enigma of the Muzo mines, Jean-Marc Lunel said, “The history of the legendary mines of Muzo began with the discovery of the New World by the Spanish conquerors in the early 16th Century. Emeralds from the Muzo mines are highly valued because of their famous saturated pure green to slightly bluish green hue, their size and their clarity.”
Although Muzo mines continue to yield high quality gemstones, very few display the purity and intense saturation of the exceptional square-cut ‘Muzo’ emerald weighing 9.27 carats, highly transparent pure crystal, free of any form of enhancement offered in the sale.
Lot sold in Geneva for CHF819,000 or USD824,720.
