31.07 Ct. Bi Color Ametrine from Bolivia

A presence that commands a room, this extraordinary transparent 31.07 carat oval bi color ametrine offers a rare marriage of size, clarity, and color that only the most discerning collectors pursue. Measuring 26.21 x 17.85 x 12.45 millimeters, the gem has been masterfully fashioned into an elegant oval with a mixed brilliant cut that maximizes scintillation and the interplay between its citrine gold and amethyst purple zones. The clarity is graded as very slightly included evaluated at eye level, a testament to the stone s natural purity, and the polish is excellent, allowing each facet to catch and return light with a brilliant, velvety fire. Untreated and wholly natural, this Bolivian ametrine arrives exactly as it was formed beneath the earth s surface, a consummate example of provenance meeting perfection, and it bears the kind of presence that transforms an object into an heirloom, and an acquisition into a defining moment of personal taste.

Imagine this ametrine set as the sovereign centerpiece of a custom creation, the kind of piece that announces achievement without needing proclamation. In a refined ring, a low, sculptural four prong setting in 18 karat rose gold will draw warmth from the golden citrine facet while the mixed brilliant cut throws violet flashes against the skin, the rose gold heightening the gem s floral luminosity and flattering every tone. For a more classical silhouette, a platinum gallery with a delicate bezel edge will lend modern restraint, the cool metal providing a striking contrast to the stone s dual personality, and allowing the purple to read with crystalline clarity. Consider an east west orientation that emphasizes the long axis and creates a conversation with the hand, or a vertical three stone composition where tapered baguette diamonds flank the ametrine, their linear grace guiding the eye from deep purple heart to honeyed rim. The stone s substantial dimensions also allow for a confident pendant, a tablet of light that rests at the throat and moves with a wearer, revealing different color ratios as it turns, the open back setting permitting daylight to play through, and the mixed brilliant cut ensuring life from every angle.

When composing the supporting palette for this ametrine, choose companions that either echo its warmth or create an elegant counterpoint, depending on the mood you wish to convey. A halo of near colorless diamonds will lift the ametrine into the realm of classical glamour, each small brilliant offering a point of fire that intensifies the gem s internal color zoning, and small pave shoulders will extend that shimmer along the band for a cohesive, museum quality look. For an opulent, tonal statement, cognac or champagne diamonds will echo the citrine field and create a unified, sunlit expression when paired with 18 karat yellow gold, a combination that reads as vintage couture. To emphasize contrast and refinement, select small violet sapphires or deep amethysts to mirror the purple aspect, set as accent stones or as a graduated cluster that draws attention to the ametrine s heart. For a contemporary, fashion forward vision, flank the stone with mint green tourmalines or tsavorite garnets, their verdant notes offering a bold contrast that makes the purple sing and the gold glow, a palette that suggests confidence and cultivated taste.
