164 Carat G-I-VS2 Emerald Cut Diamond Riviera Necklace
This graduated riviera necklace comprises 164.02 carats total weight of Emerald cut natural diamonds, spanning a color range of G through I and clarity grades from Internally Flawless to VS2, GIA certified (Rosenberg ref. 96445). Assembling a matched suite at this scale — in Emerald cut, calibrated across carat weight, color, and clarity simultaneously — is a benchmark undertaking rarely encountered in the market for important white diamond jewels.
GIA Color and Clarity: G–I Color Range, IF–VS2 Clarity Range
On GIA’s D-to-Z color scale, G through I represents the near-colorless range, where body color is minimal and visually negligible in an 18-karat white gold setting. The clarity spread — Internally Flawless through VS2 — encompasses stones with no inclusions detectable by the unaided eye, ensuring that each diamond in the suite delivers transparent, uninterrupted light performance. Matching this breadth of grading across the full complement of stones while preserving face-up visual uniformity is the defining technical challenge of a necklace of this type.
Why Emerald Cut for a Graduated Riviera Configuration
The Emerald cut’s rectangular step-cut facet arrangement produces broad, parallel reflections rather than the dispersed scintillation of brilliant cuts — a characteristic that creates a coherent visual rhythm when stones are aligned along a necklace arc. Each stone’s long axis reads as continuous with its neighbor, reinforcing the linear geometry of the graduated riviera form. The open table also renders inclusions and color directly legible, which is why Emerald cuts are the standard format for assembled suites of important white diamonds.
18-Karat White Gold Graduated Riviera Construction
The mount is handmade 18-karat white gold — an alloy selected for its neutral reflective surface, which complements near-colorless diamonds without introducing warmth or competing color. The graduated riviera design descends from a larger central stone to progressively smaller flanking diamonds, requiring precise girdle-diameter calibration to maintain even prong spacing and a consistent drape profile. At 164 carats across this many individual stones, the setting represents a substantial bench commitment, with each diamond assessed for positional compatibility before the mount is closed.
