Accent Stones Blue Sapphire Ring 2.11 Ct., Platinum 950

This ring centers a 2.11 carat oval shape blue sapphire, dimensions seven point seven seven by six point three eight by four point five seven millimeters, cut in a mixed brilliant style and originating from Ceylon Sri Lanka. The mixed brilliant cut combines a brilliant facet arrangement on the crown with a modified pavilion architecture aimed at maximizing both color saturation and scintillation. The sapphire has a clarity grade described as very very slightly included evaluated at eye level which in practical terms means inclusions are minimal and do not disrupt transparency or the stone s light transmission during normal wear. The color is described as vivid saturation, a designation that indicates a strong balance between tone and chroma, and the excellent polish ensures facet junctions are crisp and free of surface abrasion which in turn preserves the sharpness of light return and the depth of blue that is the hallmark of premium Ceylon material.

Technically the mixed brilliant faceting is chosen here to exploit the optical strengths of the oval geometry. With a measured depth of four point five seven millimeters against an average table diameter around seven point zero seven millimeters the depth percentage is approximately sixty four point six percent which is within the range that produces balanced light return for oval gems. The brilliant crown facets act to break white light into internal reflections that enhance brightness and localized flashes, while the pavilion facet scheme is tuned to maintain internal color concentration so that the vivid blue remains saturated without appearing windowed or overly dark. The excellent polish further minimizes scatter from the facet surfaces so that light travels through the stone with minimal diffusion, resulting in a crisp, three dimensional appearance. In practical viewing the combination of proportions, mixed brilliant geometry, and polish yields a vivid saturated blue that displays lively scintillation at movement and consistent body color under a range of lighting conditions.

Flanking the center sapphire are white round natural diamonds set to accentuate the center stone s color and presence. The shoulder diamonds are presented as two groups, one set having an aggregate weight of approximately zero point two four carats and the other set approximately zero point one six carats, for a combined diamond weight of about zero point four zero carats. The diamonds carry clarity grades of Very Slightly Included in the VS1 and VS2 range and a color grade of F, a near colorless designation that reads neutral to the eye when mounted in platinum. The VS clarity range in round brilliant diamonds translates to eye clean to near eye clean performance depending on individual stone characteristics and the mounting, and in this design the round brilliant cuts are faceted and polished to deliver crisp table brilliance and contrasting star and kite facet dynamics that frame the center sapphire without competing with its color. The ring is executed in platinum nine hundred fifty, a high purity platinum alloy that provides a stable, inert, and dense mounting platform which preserves prong tension and resists wear over time while maintaining a cool white backdrop that does not impart warmth to the sapphire s blue.

When comparing clarity to other high end rings on the market the sapphire s very very slightly included evaluation at eye level positions it above many commercially available sapphires which often present in the slightly included or included ranges when viewed at the same distance and in comparable sizes. In the premium colored stone market clarity expectations differ from the diamond market, but a sapphire that combines a high degree of transparency with only minute inclusions will exhibit superior color depth and light performance relative to sapphires with more pervasive inclusions that scatter light or create visible windowing. Against high end diamond set rings the shoulder diamonds in this piece, graded VS1 and VS2 and color F, meet the quality thresholds collectors expect for balance between budget and optical performance, providing clean brilliance and high color neutrality. Taken as an ensemble the transparency of the center sapphire, its vivid saturation, the precision of the mixed brilliant faceting, and the near colorless eye clean diamonds mounted in platinum nine hundred fifty deliver a level of optical refinement that competes favorably with high end sapphire rings in international markets, and exemplifies the quality standards of The Natural Sapphire Company.
