Blue diamonds have the most marvelous and enchanting hues earning its stripes as one of the most coveted, valuable and extraordinary gemstones in the world. Since the 17th century, the value of coloured diamonds have been on a consistent incline, largely due to the recognition of its rarity in comparison to their near colourless counterparts along with the intriguing variations in hues and intensities which have been discovered. What makes these spectacular gemstones a true treasure is embodied in the combination of their magnificent hues and tones owing to the trace element of boron within the crystal structure and its brilliant cutting style.
The pair of round brilliant-cut fancy intense blue diamonds showcase impeccable craftsmanship through the diamond cutter’s ability to retain such a high level of saturation within a brilliant-cut. The round brilliant-cut is rarely employed on coloured diamonds due to the high wastage of diamond rough involved with creating the shape. A diamond rough of at least double its final carat weight is required to fashion a diamond into this highly lustrous and sought-after shape. Due to the rarity of rough coloured diamonds, most cutters would opt to maximize the use of the diamond rough and cut into more commonly seen shapes such as cushion-shapes or radiant-cuts which retain more rough material and produce higher carat weights.
The strength of a coloured diamond’s colour is evaluated based on its intensity level in accordance with the Gemological Institute of America’s eight level grading scale ranging from Faint Blue to Fancy Vivid Blue. Fancy Intense is the second highest acclamation that a coloured diamond can achieve, combined with the pure blue colour, absent of any modifying secondary hues, Lot 1753 is an exquisite example of its kind.
Reveling in the presence of one exquisite round brilliant-cut fancy intense blue diamond over 1 carat is a marvel in itself, but to be presented with two well-matched as a pair is beyond rare. Together with a pair of D Colour, Internally Flawless, Type IIa diamonds, the two stunning occurrences paired together are incredible to even the most discerning collectors.
