Three Stone Bi Color Sapphire Ring 1.90 Ct., Platinum 950

This ring centers on a transparent 1.90 carat emerald cut bi color sapphire measuring 8.95 by 5.68 by 3.42 millimeters, sourced from Ceylon and heat treated to enhance stability and color. The stone exhibits an eye clean clarity grade when evaluated at eye level, with a medium intense color saturation that benefits from the step facets and large table of the emerald cut, and the polish is rated excellent. Flanking the center sapphire are white half moon shaped lab grown diamonds weighing approximately 0.50 carats in total, with clarity grades of Very Slightly Included in the VS1 and VS2 range, and a color grade of F. The entire composition is set in platinum 950, with the design emphasizing a balanced profile that places the emerald cut sapphire front and center while the half moon diamonds provide measured contrast and visual support. The use of lab grown diamonds ensures optical and structural parity with mined diamonds, as they share the same crystal structure and hardness profile, and their VS clarity grades contribute to a clean, reflective transition to the platinum setting. This ring has been conceived and finished under the standards of The Natural Sapphire Company, with attention to facet alignment, symmetry, and the integration of side stones into the shoulder architecture.

In terms of durability, the primary contributors are the intrinsic hardness of the gemstones and the robustness of the metal and setting design. Sapphire ranks 9 on the Mohs hardness scale, making it highly resistant to scratching in everyday wear, and the lab grown diamonds score 10, providing maximum resistance to abrasion for the side stones. The emerald cut offers elegant light return and clarity, but its straight facets and truncated corners can be more susceptible to mechanical impact than the rounded girdle of brilliant cuts. This design mitigates that risk by employing secure prong settings at each corner of the emerald cut, while the half moon diamonds are integrated into the shoulders in a way that reduces lateral stress on the center stone. Compared to similar three stone or three element designs on the market that rely on thinner bands, lower grade metals, or minimal prong engagement, this platinum 950 construction delivers superior long term stability. Many comparable rings cast in 18 karat or 14 karat gold will show faster surface wear, thinning of claws, and potential loosening of side stone settings over time, especially under frequent wear. Rings that use channel or bead set melee stones can offer excellent security for small diamonds, but when side stones are larger as here, the half moon configuration provides a sturdier transition and distributes force away from the corners of the emerald cut, reducing the likelihood of chips or stress fractures from incidental knocks.

Maintenance expectations and practical considerations further distinguish this ring against market alternatives. Platinum 950 is denser and more malleable than gold alloys, which means that while it resists loss of metal through rubbing and abrasion, it will develop a surface patina with wear that can be polished or left for a matte aesthetic. The relative malleability of platinum also allows prongs to be made more substantial without increasing bulk, providing enduring retention for both the center sapphire and the half moon diamonds. Heat treatment of sapphires is a conventional and stable enhancement that improves color and clarity without compromising structural integrity, and it is not reversible under normal environmental conditions. For routine care, we recommend inspection of prongs and shoulders every six to twelve months, professional cleaning and re-polishing as desired, and prompt re-tipping of prongs if any signs of wear are observed. Avoiding hard impacts, strong chemicals, and prolonged exposure to abrasive materials will extend the ring s service life. When compared to lighter, more ornate designs with filigree or pavé shoulders that can trap dirt and are more vulnerable to catching, this ring s clean platinum shoulders and securely set half moon diamonds offer an advantageous balance between visibility and protection. At The Natural Sapphire Company we document each ring s specifications and finish, and we advise that when durability is a priority, the combination of a well protected emerald cut sapphire, substantial half moon side stones, and a platinum 950 mounting provides a coherent solution that performs well relative to many similar designs on the market.
