1 Carat Fancy Vivid Blue SI1 Heart Shape Diamond Ring
The center stone is a 1.35-carat Fancy Vivid Blue SI1 Heart Shape natural diamond, GIA certified (Rosenberg ref. 95152). Natural blue diamonds owe their color to the presence of boron atoms within the crystal lattice — a geological event so rare that fancy color blue diamonds account for a fraction of a percent of all fancy color submissions to GIA globally. At Fancy Vivid saturation in a heart shape exceeding one carat, this stone occupies a category rarely encountered in the open market.
GIA Color Grade: Fancy Vivid Blue
GIA grades natural blue diamonds on a scale from Faint through Fancy Deep. Fancy Vivid represents the peak of pure saturation on that scale — indicating strong, evenly distributed color with high tone observed face-up; stones graded Fancy Deep carry greater darkness and are valued on a separate basis. SI1 clarity places the diamond within the slightly-included range: inclusions are detectable under 10× magnification but remain imperceptible to the unaided eye and have no material impact on light transmission at this carat weight.
Why Heart Shape for a Fancy Vivid Blue
The heart shape is a modified brilliant cut derived from the pear, incorporating a defined cleft at the crown. Its brilliant facet pattern — typically 56 to 58 facets — generates strong light return while preserving the body color saturation that drives value in fancy color diamonds. For a Fancy Vivid Blue, the brilliant arrangement maximizes face-up color expression without the masking effect that can occur in step cuts, making it a structurally sound choice for a stone graded at the upper end of GIA’s saturation scale.
Handmade Platinum Solitaire Setting
The diamond is mounted in a handmade platinum solitaire setting engineered to secure a heart shape without obstructing the stone’s lobes or cleft — the two most structurally vulnerable points of this outline. Platinum’s density and 95% purity make it the standard metal for prong settings on high-value fancy color diamonds: it resists prong wear over decades of use and introduces no warm tonal interference that could interact with the blue body color. The solitaire construction directs all visual attention to the stone itself.
