Halo Green Sapphire Ring 1.66 Ct., 18K Rose Gold

Exclusively offered by The Natural Sapphire Company, this ring presents a rare, transparent 1.66 carat cushion shape green sapphire, precisely measured at 7.60 x 5.85 x 4.18 mm, cut in a mixed brilliant style that fuses modern sparkle with classic form. The sapphire is eye clean evaluated at eye level, with medium intense color saturation and an excellent polish, and importantly it is completely natural with no enhancement, originating from Montana. Surrounding the center stone is a halo of white round natural diamonds weighing approximately 0.30 carats, clarity Very Slightly Included VS1, VS2, color grade F, complemented by an additional group of white round natural diamonds totaling approximately 0.153 carats, clarity Very Slightly Included VS1, VS2, color grade F. The entire composition is set in warm 14K rose gold, chosen to accentuate the green hue and to offer a bespoke canvas that feels inherently personal. This is a limited expression of nature and craft, designed for the collector who values provenance, purity, and the quiet distinction of owning something both uncommon and utterly refined.

When comparing light performance, the mixed brilliant cushion cut of this Montana sapphire offers a distinct advantage over both pure step cuts and traditional round brilliants, marrying exceptional scintillation with depth of color. Against a round brilliant, the mixed cushion delivers broader flashes and a softer, more antique silhouette while still returning lively fire and dispersion, creating flashes that feel both energetic and elegant. Against step cuts such as emerald or asscher, which emphasize clarity and linear hall of mirrors reflections, this mixed brilliant cushion emphasizes scintillation and sparkle over planar light return, therefore appearing more alive in motion and more luminous in varied lighting. The pavilion and crown geometry of a mixed brilliant cushion unlocks balanced brilliance and contrast, especially when the stone is eye clean and well polished as this Montana gem is, allowing light to travel without obstruction and reveal the sapphire s natural green with crisp highlights. The surrounding F color, VS clarity diamonds amplify this effect, framing the center with white brilliance that intensifies perceived color and sparkle. In short, this piece is for the connoisseur who wants the dynamic light play of a brilliant style, the depth and character of a cushion outline, and the assurance of natural, untreated origin, a combination that underscores the exclusivity and enduring value that only The Natural Sapphire Company can present.
