Platinum and Fancy Blue Diamond Ring, Tiffany & Co., Circa 1900

The modified marquise-shaped diamond of fancy blue color weighing 3.54 carats, within a delicate mounting set with old European-cut and single-cut diamonds weighing approximately .35 carat, size 3½, bearing partial signature 'T' for Tiffany & Co., two diamonds missing.  With fitted box signed Tiffany & Co.

Accompanied by GIA report no. 5141498993 stating that the diamond is Fancy Blue, Natural Color, VS1 clarity. As noted in the catalogue description, two small diamonds are missing. Overall surface wear to the mounting and thinning/warping to the shank commensurate with age. The color is on the strong end of the Fancy Blue range. The near colorless diamonds are approximately F-H color, VS-SI clarity. The first letter of the Tiffany signature may be found on the shank interior. The remainder of the signature has been lost to resizing and wear. The signed box appears to date from the same period as the ring and is believed to be original.

Centered by a diamond of enchanting cut and color, this exquisite piece has remained in the family since being presented to the current owner's great-great grandmother.  The elegant mounting, with its millegrained borders and endearingly sweet floral motifs, prefigures the refinement and delicacy of the Edwardian era.  Turn-of-the-century rings, particularly those by esteemed houses such as Tiffany & Co., appear with diminishing frequency in today's marketplace.  For such a piece to be set with a Fancy Blue diamond is rarer still, making this ring a truly exceptional jewel.
