1 Carat Fancy Green Yellow SI2 Heart Shape Diamond Ring
The center stone is a 1.00-carat Fancy Green SI2 Heart Shape natural diamond, GIA certified (Rosenberg ref. 6210). Natural green diamonds derive their color from exposure to radiation during formation in the earth — a geological process so rare that GIA-graded Fancy Green stones represent a fraction of a fraction of annual fancy color submissions, making even one-carat specimens rarely encountered in the market.
GIA Color Grade: Fancy Green
GIA grades green diamonds on a scale progressing from Faint through Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, and Fancy Deep. Fancy Green designates consistent, face-up green saturation originating from the stone’s body color — a grade that confirms the color is natural and not a product of treatment, which GIA notes explicitly in the grading report. SI2 clarity places the diamond in the slightly-included range; at one carat, inclusions at this grade are typically not detectable to the unaided eye and carry no consequence for light performance or structural integrity.
Why Heart Shape for a Fancy Color Diamond
The Heart Shape is derived from the round brilliant, retaining a full modified brilliant facet pattern that generates high light return across the entire outline. For a Fancy Green diamond, this facet structure distributes color evenly face-up rather than concentrating it in localized zones — a critical consideration given how rare uniform green saturation is in natural stones. The symmetrical lobes of a well-cut Heart also allow the color to read at full intensity from standard viewing distances.
Platinum Micropavé Setting and Construction
The diamond is handmade in platinum with a micropavé band — a construction in which small accent diamonds are set in closely spaced individual beads along the shank, creating continuous brilliance without competing with the center stone’s color. Platinum at 95% purity provides the structural density required to secure micropavé beads over time, and its naturally white tone maintains color neutrality against the green center without the warmth introduced by yellow or rose gold alloys.
