5.05 ct. Oval Polygon Step Cut Lab Grown Diamond, Fancy Yellowish Brown, VS2, IGI Certified.

5.05 Carats of Fancy Color. A Cut Designed to Captivate.

The oval polygon step cut is a rare intersection of two diamond traditions — the sweeping silhouette of the oval and the architectural precision of the step cut. Where a brilliant-cut oval scatters light into a thousand points of fire, the polygon step cut channels it into broad, mirror-like flashes that move with the stone. At 5.05 carats of Fancy Yellowish Brown, independently certified by the International Gemological Institute, this diamond occupies a category that very few stones reach. Fancy color diamonds are graded on an entirely different scale than white diamonds — color is not a flaw here, it is the point. The warm, cognac-toned depth of a Fancy Yellowish Brown is rich, distinctive, and impossible to replicate. This is not a stone for blending in.

The Specifications

Why Fancy Yellowish Brown at 5.05 Carats

Fancy color diamonds are among the most sought-after stones in the world — and among the most misunderstood. A Fancy Yellowish Brown is not a near-colorless stone with an undesirable tint. It is a stone whose color has been independently evaluated and confirmed as a true fancy color grade, placing it in an entirely different category of desirability. The warm, cognac-to-champagne spectrum of Fancy Yellowish Brown pairs exceptionally well with yellow gold and rose gold settings, where the metal's warmth amplifies the stone's natural depth. At 5.05 carats, the oval polygon step cut gives this color room to breathe — the broad facets allow the hue to saturate evenly across the stone's surface, creating a richness that smaller stones simply cannot achieve.

Setting Recommendations

A 5.05 carat fancy color oval is most beautifully showcased in settings that complement its warmth — a sleek four- or six-prong solitaire in 18k yellow gold or rose gold, a halo setting with white or champagne diamond accents, or a three-stone setting with pear or half-moon side stones. The oval polygon step cut's elongated silhouette is particularly striking in a bezel or east-west setting for a modern, editorial look.
