Three Stone Purple Sapphire Ring 0.66 Ct., 14K White Gold

This ring from The Natural Sapphire Company presents a studied balance of proportion and finish, centred on a transparent purple sapphire of 0.66 carat. The sapphire is cut in a cushion shape with a mixed brilliant cutting scheme, and its dimensions measure 5.68 by 4.18 by 3.20 mm. The stone displays vivid color saturation and an eye clean clarity grade when evaluated at eye level, and the overall polish is excellent. The gem originates from Ceylon Sri Lanka, and its presentation within a classic three stone arrangement is understated and precise. The mounting is executed in platinum 950, chosen for its strength and neutral white backdrop, which supports the optical performance of the sapphire and the accompanying white diamonds.

The precision of the sapphire faceting is the defining feature of this piece, and it is evident in both the macro proportions and the micro facet junctions. The mixed brilliant scheme employs a carefully controlled distribution of pavilion and crown facets that optimize light return for a gem of these dimensions. The crown facets are arranged to balance contrast and fire, producing consistent scintillation across the table when viewed from multiple angles. On the pavilion the facet angles are calibrated to the gem index of refraction, which reduces light leakage at the girdle and enhances overall brightness. Facet terminations are crisp, with symmetry maintained across opposing facets, and the excellent polish allows uninterrupted transmission of light, so that the vivid purple shows depth without appearing blocked by surface irregularities.

The two white diamonds placed as asscher octagon shapes flank the sapphire, and their precise geometry is selected to complement the mixed brilliant pattern of the centre stone. Together the diamonds total approximately 0.30 carats, with individual clarity grades in the Very Slightly Included range of VS1 and VS2, and a color grade of F. The asscher octagon form provides a stepped faceting effect that contrasts with the mixed brilliant cushion, creating a refined balance between broad flashes of light and fine pinfire scintillation. The diamonds are matched for tone and proportion so that their facet planes align visually with the sapphire setting, and their polished surfaces and precise table sizes contribute to a clean transition from stone to stone across the shoulder of the ring.

The setting and fabrication emphasize restraint and technical care, with the platinum 950 band and prong work designed to secure the stones while minimizing metal intrusion into the light path. Prongs are shaped and positioned to support the sapphire at four cardinal points, allowing light to reach the pavilion without obstruction, and the diamond mounts are set to maintain symmetry and spacing. Final finishing checks include verification of facet alignment under magnification, assessment of polish consistency across metal surfaces, and inspection for any micro abrasions that could affect light performance. The result is a ring that demonstrates how exacting faceting and considered mounting produce a cohesive optical result, and The Natural Sapphire Company provides documentation of the sapphire origin and gem specifications to support the technical description and provenance of this piece.
