Three Stone Yellowish Green Sapphire Ring 1.87 Ct., 18K Yellow Gold

This ring centers on a transparent 1.87 carat oval yellowish green sapphire sourced from Montana, offering a distinct hue and a clear, open appearance. The sapphire measures 8.57 by 6.99 by 3.97 millimeters and is faceted in a mixed brilliant cut, a proportioning that enhances sparkle while preserving the gem body and color. The stone presents a medium color saturation and has been graded as slightly included when evaluated at eye level, a characteristic that confirms its natural origin and contributes subtle character without compromising overall visual appeal. The sapphire shows an excellent polish across all facets, which maximizes light return and enhances its pale yet lively green tone. Importantly, this sapphire has no enhancement, a quality that preserves its natural formation characteristics and provides a direct connection to its place of origin.

Complementing the center sapphire are natural white diamonds selected for balance and refinement. Two half moon shaped diamonds flank the sapphire, weighing approximately 0.50 carats in total, with clarity grades of Very Slightly Included BS1 and Very Slightly Included VS2, and a color grade of I. A line of white round shaped diamonds runs partway along the shank, weighing approximately 0.30 carats in total, graded VS for clarity and F G for color. The combined diamond weight is approximately 0.80 carats, a calibrated accompaniment that frames the sapphire and enhances its presence without overpowering the primary gem. The diamonds are cut and matched for consistent brightness and tone, with careful attention to symmetry and siting, ensuring even visual flow and a measured contrast with the yellowish green sapphire.

The mounting is executed in 14 karat yellow gold, chosen to complement the warm undertones of the sapphire while providing enduring structural integrity. The ring exhibits refined metalwork, with secure prong settings for the oval sapphire and meticulous seats for the half moon side stones, and a contrasting channel for the round accent diamonds along the shoulder. The craftsmanship emphasizes both aesthetics and longevity, with attention to prong heads and gallery work that allows light to penetrate the stones while maintaining protection. The choice of 14 karat yellow gold balances everyday wearability with a warm color that harmonizes with the sapphire, creating a cohesive and considered design that reads as both classic and contemporary.
