19.83ct Heart Shape D VVS1 GIA Pendant Necklace
The center stone is a 19.83-carat D color VVS1 Heart Shape natural diamond, GIA certified (Rosenberg ref. 96643). Heart Shape diamonds at this carat weight are rarely encountered in the D color grade — at nearly 20 carats, the convergence of colorless body color, top-tier clarity, and an outline cut demanding exacting symmetry places this stone among the most consequential natural diamonds to enter circulation. Stones of this specification represent a structurally limited segment of annual GIA submissions for fancy-shaped white diamonds above 15 carats.
GIA Color Grade: D and Clarity Grade: VVS1
D is the highest designation on GIA’s D-to-Z color grading scale, indicating the complete absence of detectable body color under controlled lighting and magnification — a grade achieved by a small fraction of diamonds submitted each year regardless of size. VVS1, or Very Very Slightly Included First Degree, denotes inclusions that are essentially invisible under 10× magnification; at 19.83 carats, this grade ensures uniform optical performance across the entire face-up surface without compromise to light transmission or brilliance.
Why Heart Shape at This Scale
The Heart Shape is a modified brilliant cut derived from a pear silhouette, engineered to deliver high light return through its 56 to 58 facets while projecting an immediately recognizable outline. At nearly 20 carats, the cut places extraordinary demands on the cutter: the two lobes must mirror each other with precise symmetry, as asymmetry is amplified rather than concealed at large carat weights. Achieving this geometric balance in a D VVS1 stone at this scale requires a level of rough selection and manufacturing precision that distinguishes this stone categorically from standard fancy-shaped production.
Platinum Pendant Setting and Chain Construction
The diamond is mounted as a pendant in handmade platinum — the standard metal for exceptional white diamonds given its 95% purity, high density, and resistance to prong deformation over decades of wear. The setting is constructed to expose the full Heart Shape outline from above, with prongs positioned at the lobes and lower point to secure the stone without interrupting the silhouette at the cleft. A matching platinum chain suspends the pendant, maintaining metal consistency throughout and distributing the stone’s weight without stress on the mount.
