The cushion-shaped fancy intense green diamond weighing 6.13 carats, within a brilliant-cut pink diamond surround, extending to the half-hoop, mounted in 18k rose gold, ring size 6

Accompanied by report no. 2155792241 dated 4 December 2023 from the Gemological Institute of America stating that the 6.13 carat diamond is fancy intense green, natural colour, VS2 clarity, with excellent polish

Also accompanied by a supplemental letter stating that natural green diamonds are among the rarest of all coloured diamonds encountered at GIA. This is especially true when the green hue is unmodified regardless of the depth of colour. The cushion modified brilliant described in the above referenced report not only is an "unmodified" green hue, but it is also medium in tone and moderately strong in colour resulting in a Fancy Intense Green colour grade. This is very rare for natural green diamonds. The 6.13 carat diamond described here showed diagnostic properties that indicated that the origin of colour is natural. The combination of its natural origin and saturated colour makes it an extremely unusual occurrence
