Antique Style Green Sapphire Ring 4.50 Ct., Platinum 950

This ring centers on a transparent 4.50 carat oval green sapphire, with exact dimensions of 10.61 x 8.55 x 5.54 millimeters and a mixed brilliant cut that balances optical return with color saturation. The mixed brilliant cut on this oval integrates a modified brilliant crown over a pavilion that is optimized for light return, producing lively scintillation without sacrificing the depth of color that defines fine green sapphires. Proportions are disciplined for this shape, the depth measures 5.54 millimeters which corresponds to approximately 57.8 percent of the average diameter, a ratio that supports both strong face up presence and stable durability. Clarity is graded very slightly included at eye level, meaning the stone appears clean to unaided vision while retaining natural internal characteristics that confirm its origin and growth history. The polish is excellent, contributing to crisp facet junctions and precise facet angles that promote symmetrical light performance across the table and crown facets.

Color is the dominant character of this sapphire, exhibiting intense saturation of green with balanced tone that reads vividly in both daylight and artificial light. The green hue derives from natural trace element chemistry within the corundum, and the material shows controlled pleochroism that enhances depth as the stone moves. Origin is Madagascar, a source known for stones with strong chroma and attractive body color, and the combination of cut and material quality results in a stone that communicates natural beauty with minimal intervention. Enhancement has been limited to customary heat treatment, applied to refine and stabilize the intrinsic color while leaving the crystal structure intact. This is a modest enhancement that optimizes the stone for maximum appeal, but it is not required to create the color, rather it refines the existing tones to a level consistent with collector expectations.

The surrounding and accent diamonds are selected to support and amplify the sapphire without overwhelming it. The ring incorporates natural white round shaped diamonds totaling approximately 0.216 carats in primary accent weight, additional small accents of approximately 0.04 carats, and a further grouping of approximately 0.15 carats, all evaluated at clarity VS and a color grade that reads F and G. These diamonds are cut to tight tolerances for light performance, and their round brilliant geometry provides high brilliance and fire which contrast with the sapphire s deeper green tone. The placement of the diamonds follows a deliberate design logic, using halo and shoulder positions to reflect light into the sapphire from multiple angles. This layered approach to accent stone selection and positioning increases apparent visual brightness around the crown, while the VS clarity means inclusions do not distract from the overall visual field when viewed at normal wearing distances.

The ring setting is executed in 18K white gold, chosen for its balance of strength and lustrous color that complements the green center while providing a secure architecture for the mounting. Craftsmanship techniques include precision stone fitting, clean bezel and open gallery work, and detailed hand engraving along the shoulders and gallery that contribute to the piece s overall proportion and tactile quality. The accent diamonds are bead set and flush set where appropriate to maintain profile and durability, and the gallery has been engineered to allow light to enter and exit the pavilion efficiently, which enhances the center stone s apparent color saturation and brightness. The Natural Sapphire Company stands behind the selection and finish of this piece, and we can provide gem reports and further technical data on request, including facet mapping and detailed observations of inclusions and polish. Given the stone s natural transparency, strong color, and only modest heat treatment, minimal enhancement was required to bring this sapphire to its present state, ensuring long term stability and enduring natural beauty.
