20 Carat D-F Flawless-VS2 Eternity Band Radiant Cut Diamond Ring
This eternity band comprises a full-circle calibrated set of Radiant cut natural diamonds totaling 19.60 carats, graded D through F in color and Flawless through VS2 in clarity, GIA certified (Rosenberg ref. 700776). Assembling a matched run of Radiant cuts at this total weight — with color grades confined to the colorless tier and clarity grades ranging from Flawless to VS2 — represents a sourcing challenge rarely resolved in a single piece; the consistency required across an eternity band eliminates the vast majority of available stones before cutting begins.
GIA Color and Clarity Grades: D–F, Flawless–VS2
On GIA’s color scale, D through F defines the colorless range — stones that show no detectable body color under standardized grading conditions and transmit white light without warm deviation. Flawless indicates the complete absence of internal and external characteristics under 10× magnification, while VS2 marks the outer boundary of the very-slightly-included range, where inclusions remain invisible to the unaided eye and carry no consequence for light performance. The band’s color and clarity window is deliberately narrow, ensuring visual uniformity across every stone face-up.
Why Radiant Cut for a Full-Circle Eternity Setting
Radiant cuts combine a rectangular or square outline with a modified brilliant facet structure, producing a higher brilliance output than step cuts while offering a flat, uniform table height that simplifies calibration across an eternity setting. Their straight edges allow tight seat-to-seat fitting with minimal metal between stones, which maximizes the continuous diamond surface visible face-up. The cut’s geometric stability also distributes pressure evenly at each setting position, reducing stress concentration in a full-circle mount.
Platinum Eternity Construction
The band is handmade in platinum, a metal selected for its density and 95% purity, which provides the clamping resistance needed to secure individually set Radiant cuts over extended wear. Each stone is seated and calibrated to maintain consistent crown height and girdle alignment around the full circumference, a standard that distinguishes hand-fabricated eternity bands from cast production work. Prong placement is engineered to protect the corners of each Radiant cut — the points of highest vulnerability in a rectangular outline — without interrupting the visual continuity of the band.
