73 Carat G-I-VS2 Emerald Cut Diamond Riviera Necklace
The necklace comprises a calibrated graduated suite of GIA-certified Emerald cut natural diamonds totaling 72.53 carats, spanning G-to-I color and Internally Flawless-to-VS2 clarity (Rosenberg ref. 96478). Assembling a riviera necklace of this combined weight in step-cut stones — each individually graded — represents a scale of acquisition rarely encountered outside institutional or generational collections. The progressive decrease in stone size from center to terminus is achieved through precision calibration across the full suite.
GIA Color and Clarity Range: G–I and IF–VS2
G through I on GIA’s D-to-Z scale falls within the near-colorless range — grades at which the absence of body color is not perceptible to the unaided eye in face-up position. Maintaining visual color uniformity across a graduated necklace demands careful stone-by-stone selection, as tonal drift between adjacent steps becomes apparent in the step-cut’s broad, open facets. Clarity spanning Internally Flawless to VS2 places the suite firmly in the upper tier of GIA’s scale: IF stones carry no detectable inclusions or blemishes under 10× magnification, while VS2 stones contain minor inclusions invisible without magnification and with no measurable effect on light return.
Why Emerald Cut for a Graduated Riviera Format
The Emerald cut’s step-cut architecture — long parallel facets, a broad table, and cropped corners — produces wide, mirror-like flashes rather than dispersed scintillation. In a riviera necklace, this geometry allows the suite to present as a unified linear element rather than a collection of competing light sources. The rectangular outline also enables tighter stone-to-stone calibration, which is essential for achieving the geometric precision that defines a classical graduated riviera.
18-Karat White Gold Construction and Riviera Setting
The stones are mounted in 18-karat white gold, a metal selected for its structural rigidity at the gauge required to support a necklace of this combined mass without excessive weight on the collet walls. Riviera construction employs individually linked settings — each stone secured within its own mount — allowing independent movement that distributes tension across the full length and reduces concentrated stress at any single junction. The graduated layout requires each diamond to be cut to precise dimensional tolerances so that the visual rhythm of the descent reads continuously and without interruption across the necklace’s arc.
