Three Stone Blue Sapphire Ring 15.16 Ct., 14K Yellow Gold

This ring centers on a single, transparent 15.16 carat oval blue sapphire, measuring 17.47 x 15.24 x 6.10 mm, with a modified brilliant cut, a clarity grade described as very slightly included when evaluated at eye level, dark color saturation, and an excellent polish. The sapphire is heat treated and originates from Thailand. The gem sits within an 18K yellow gold mounting, accompanied on each shoulder by a single marquise shaped natural white diamond, with the combined diamond weight of approximately 1.00 carats, clarity grades of VS1 and VS2, and a color grade of F. The presentation of these technical attributes provides a precise account of the material composition and the visual qualities that determine both aesthetic character and market value.

The provenance of the sapphire contributes materially to the ring’s narrative and perceived value. Thailand has a long established role in the sapphire trade, both as a source of stones and as a center for cutting and trading, with a history that ties modern gem commerce to generations of lapidary expertise. Stones from this region are often sought for their deep, saturated blues and for the skilled cutting traditions available locally, which in this example are reflected in the modified brilliant cut and the quality of the polish. The history of a gem can influence its desirability, because origin, treatment practices, and the reputations of regional lapidaries factor into how collectors and connoisseurs assess rarity and authenticity.

The large carat weight and the chosen cut work together to create an impression of depth and presence, while the clarity and polish determine how light travels through the stone and how inclusions affect appearance at typical viewing distances. A modified brilliant cut on an oval outline is selected to maximize return of light and to emphasize the body color, rather than to prioritize scintillation alone. The description of the sapphire as very slightly included at eye level indicates that the stone presents as visually clean to the unaided eye, with minor natural characteristics that do not materially detract from the visual impression, and which in many cases authenticate natural origin. Heat treatment is a widely accepted enhancement for sapphires, applied to optimize color and clarity, and when disclosed, it informs buyers of the gem’s condition and how it has been stabilized to achieve the dark saturation evident in these images. The excellent polish enhances surface reflectivity and aids in maintaining the stone’s appearance through regular wear.

The supporting elements and the mounting complete the piece as an object of design and function. The two white marquise diamonds flank the center sapphire, together totaling approximately 1.00 carats, with VS1 and VS2 clarity and F color, providing a color neutral contrast that frames the blue center without competing with it. The diamonds are set in an 18K yellow gold structure, which provides both a warm visual counterpoint to the cool blue of the sapphire and the structural integrity required for daily wear. The craftsmanship in the prong work and the under gallery is executed to support the sizeable center stone while allowing light to penetrate and interact with the pavilion facets. The combined choices in gemstone selection, cut, treatment disclosure, and precious metal convey both immediate aesthetic impact and long term considerations such as durability, provenance, and maintenance. The Natural Sapphire Company provides documentation of the stone attributes and origin, and this ring is presented with clarity about its treatment and grading, enabling informed ownership and appropriate care recommendations.
