19.83ct Heart Shape D VVS1 GIA Pendant Necklace
The center stone is a 19.83-carat natural heart shape diamond graded D in color and VVS1 in clarity by the GIA (Rosenberg ref. 9261/96643). D is the highest possible color grade and VVS1 is the second-highest clarity grade on the GIA scale, a combination found in less than one percent of natural diamonds at this carat weight.
GIA D Color and VVS1 Clarity
D-color denotes complete absence of detectable hue under controlled grading conditions, the topmost designation on the GIA D-to-Z colorless scale. VVS1 (Very, Very Slightly Included, first tier) describes inclusions so minor that they are extremely difficult for a skilled grader to detect under 10× magnification. At 19.83 carats, the rarity of stones simultaneously achieving D color and VVS1 clarity makes this pendant a high-jewelry-tier acquisition.
Why Heart Shape for D-Color Diamonds
Heart shape diamonds are cut with 59 facets in a modified brilliant pattern, with the shape requiring exceptional symmetry between the two lobes and a well-defined cleft to be considered well-cut. D-color stones in heart shape are particularly sought after because the colorless body allows the brilliant facet structure to deliver maximum white light return without the interference of any tinted background. The recommended length-to-width ratio for heart shapes is 0.90–1.10, a range that preserves silhouette balance while maximizing face-up area.
Platinum Pendant Setting
The pendant is handcrafted in platinum, an alloy with a minimum 95% pure platinum content by international jewelry standards, selected for its naturally white tone that does not transmit any color to the D-grade center stone. The setting suspends the heart from a fine bail oriented to display the cleft uppermost, presenting the lobes in their characteristic upright position. Platinum’s density supports the secure four- or five-prong retention required for a stone of nearly twenty carats.
