Three Stone Bluish Green Sapphire Ring 4.60 Ct., 14K White Gold

This ring centers on a transparent 4.60 carat cushion shape bluish green sapphire, with exact dimensions of 8.98 by 8.26 by 6.40 mm, cut in a mixed brilliant faceting scheme. The mixed brilliant approach combines a brilliant style crown with a step influenced pavilion structure, a configuration chosen to balance brilliance and color saturation. The relatively deep pavilion profile and the careful faceting transitions optimize internal reflection and return of blue and green wavebands, so that the medium intense color saturation reads as vivid under typical lighting. The sapphire was evaluated as slightly included at eye level, and these internal features are positioned and minimized by the cutter so they do not disrupt the stone s overall transparency. With excellent polish throughout, surface scattering is reduced, which allows maximum light transmission through the table and crown facets, preserving the stone s innate clarity and ensuring the cushion outline remains clean and well defined. The gemstone is natural, originating from Montana, and it has no enhancement, allowing its native crystalline color to be the principal visual characteristic.

The platinum 950 mounting plays a critical optical role in how the sapphire s color and clarity are perceived. Platinum s white neutral reflection diminishes warm metal spill back into the stone, unlike yellow metals which can bias the appearance toward gold tones. The substantial white metal mass around the pavilion and undergallery reflects neutral light back through the sapphire s facets, reinforcing the bluish green saturation while maintaining tone balance. The setting uses four prominent prongs positioned near the cushion corners to secure the girdle while leaving the crown and table minimally occluded, permitting direct top lighting and unimpeded observer view. The open undergallery and carefully angled seat prevent blockage of side light entering the pavilion, which increases constructive internal reflections and reduces apparent extinction. Meticulous hand finishing of the prongs and the gallery ensures consistent facet to metal relationships, so that the sapphire s slightly included clarity remains visually unobtrusive under normal viewing distances.

The side stones are specified to a high color and clarity standard to act as an optical foil for the center sapphire. The two white pear shaped lab grown diamonds weighing approximately 0.80 carats in total, graded VS1 and VS2 for clarity and E for color, provide neutral, high whiteness accents that elevate the perceived saturation of the central bluish green field by contrast. The additional white round shaped natural diamonds weighing approximately 0.053 carats with VS clarity and F or G color, and the larger group of round shaped natural diamonds totaling approximately 0.113 carats with VS clarity and F or G color, are integrated as high scintillation accents. Their high color grades minimize any warm or yellow spill into the visual field, so the eye interprets the sapphire s hue in higher contrast. The pear profiles flank the cushion in a manner that complements the mixed brilliant facet geometry, with their pointed ends oriented away from the center to channel light into the pavilion planes, creating dynamic side flash that rim lights the sapphire and reduces the visual prominence of minor internal features. The small round diamonds are set to add micro scintillation adjacent to the gallery and shoulders, increasing perceived brilliance without competing in hue.

Craftsmanship and setting technique were executed to emphasize both color saturation and clarity resilience. The prong geometry was designed to secure the stone at structurally sound pressure points while optimizing facet exposure, and the prong tips were finished to match the polish grade of the sapphire so there is no stray surface reflection that could disrupt the viewer s perception. Seat geometry and clearance dimensions were controlled to allow the sapphire s pavilion to breathe and to permit routine inspection, while the undergallery was open enough to facilitate light ingress yet engineered to avoid trapping oils or moisture. The use of platinum 950 provides long term metal stability and minimal maintenance of finish, preserving the initial optical relationships between metal and gem. This ring is presented by The Natural Sapphire Company, and it demonstrates an integrated design philosophy where facet strategy, stone proportions, diamond selection, and metal choice are coordinated to maximize the sapphire s medium intense bluish green saturation and to present its slightly included clarity as an inherent element of natural origin rather than a detracting factor.
