BLEU ROYAL EXCEPTIONAL COLOURED DIAMOND AND DIAMOND RING
NOTE: “Fancy Vivid” is the ultimate color grade for most Fancy Color Diamonds (with few exceptions). While it is still a range of saturation – there are some Vivid diamonds that are more Vivid than others – once they reach the Vivid range, they are quite spectacular, as is evidenced here!
… and not only is the Fancy Vivid Blue important, the side stones, 3 carat pear shapes, are both D color, Internally Flawless, Type IIa! WOW!

FANCY DEEP GREEN, NATURAL COLOR DIAMOND AND DIAMOND RING
Fancy deep green cushion modified brilliant-cut diamond – TWO REPORTS
NOTE: Fancy Green colored diamonds are extremely rare and difficult to confirm if the color is natural or not. To make absolutely certain, as certain as one can be with green diamonds, this diamond was graded by GIA in 2019, and then again, this year 2023. Both reports confirm that the diamond is of Natural Color. – gr

TREATED FANCY VIVID YELLOW DIAMOND RING
NOTE: Even though the diamond has been color enhanced, because the color is permanent, GIA went ahead and color graded the diamond as Fancy Vivid Yellow. This did not help the value, as the diamond sold for CHF 400,000 LESS than its high estimate!
