79 Carat All D Flawless Pear Shape Diamond Riviera Necklace
The necklace comprises a matched suite of natural Pear and Marquise cut diamonds totaling 79.18 carats, each stone graded D color and Flawless clarity, GIA certified (Rosenberg ref. 95642). Assembling a graduated Riviera necklace from diamonds at a single color and clarity grade at this aggregate weight requires years of selective sourcing — suites of this scale, uniformly graded at the apex of both the color and clarity scales, are rarely encountered in any market context.
GIA Color and Clarity: D Flawless Across the Full Suite
D is the highest grade on GIA’s D-to-Z color scale, indicating a complete absence of detectable body color under standardized grading conditions. Flawless is GIA’s highest clarity designation, confirming no inclusions or blemishes are present under 10× magnification. Maintaining D/FL uniformity across both Pear and Marquise shapes in a graduated sequence — where each stone must read identically to its neighbors in face-up appearance — adds a further layer of rarity beyond total carat weight alone.
Why Pear and Marquise Cuts for a Graduated Riviera Format
Pear and Marquise cuts share elongated profiles that lie flat against the décolletage, distributing reflected light across a wider surface area than round brilliants of equivalent carat weight. Both cuts employ modified brilliant facet arrangements, preserving high light return while the alternating silhouettes create a rhythmic visual continuity along the necklace line. The graduated layout — stones decreasing in size symmetrically from center to clasp — is the defining characteristic of the Riviera format, designed to follow the natural curve of the neckline.
Platinum Handmade Construction and Graduated Calibration
The necklace is handmade in platinum, the standard metal for assemblies of this value given its 95% purity, structural density, and long-term dimensional stability in prong and bezel elements. Graduated Riviera construction requires each individual setting to be calibrated to the exact diameter of its stone, ensuring consistent stone height, parallel girdle planes, and uninterrupted visual flow across the full length of the piece.
