72 Carat D-F Flawless-VS2 Asscher Cut Diamond Riviera Necklace
This riviera necklace is composed of GIA-certified natural Asscher cut diamonds totaling 71.96 carats, graded across a tightly calibrated color range of D through F and a clarity range of Flawless through VS2 (Rosenberg ref. 700768). Assembling a matched riviera of this total weight in Asscher cut — a shape with strict requirements for symmetry and optical precision — places this piece in a category rarely encountered at auction or in private collections. The combined carat weight, matched-lot sourcing, and consistent grading across every stone represent a procurement challenge that limits supply structurally, independent of fluctuating market conditions.
GIA Color and Clarity Grades: D–F and Flawless–VS2
GIA’s D-to-Z color scale begins at D, the designation for a chemically pure, structurally perfect crystal that transmits light with no detectable body color. The D–F range encompasses the three top grades — colorless by any standard instrument or trained eye. Flawless indicates no internal or external characteristics visible under 10× magnification; VS2 marks the lower boundary of the very-slightly-included range, where any inclusions remain invisible to the unaided eye and have no measurable effect on light performance.
Why Asscher Cut for a Riviera Necklace
The Asscher cut — an octagonal step cut with a square outline and deep, concentric pavilion facets — produces a distinctive hall-of-mirrors optical effect rather than the dispersed brilliance of modified brilliant cuts. In a continuous riviera setting, uniform step-cut geometry creates a coherent, low-distortion light pattern across the full necklace length, allowing the calibrated white color of each stone to read as a single unified field rather than competing points of light. The cut’s rectilinear facet structure also demands exceptional clarity, which the Flawless–VS2 range fully supports.
Handmade Platinum Riviera Construction
Each diamond is set in handmade platinum, the standard metal for high-carat matched diamond jewelry due to its 95% purity, structural density, and resistance to prong deformation over decades of wear. Riviera construction requires every collet or bezel unit to be individually calibrated to the stone it holds, ensuring consistent stone height, uniform face-up presentation, and uninterrupted line across the necklace. Platinum’s white, non-reflective surface does not introduce color interference at the girdle, preserving the integrity of each stone’s D–F grade.
