Solitaire Green Sapphire Ring 0.70 Ct., Silver

This ring centers a transparent 0.70 carat green sapphire cut on the trillion, with precise dimensions of 5.91 by 5.23 by 3.20 millimeters. The measured depth yields an effective depth percentage of approximately 57 percent, a proportion that supports balanced light return for a triangular brilliant style. The stone is graded eye clean at normal viewing distance, showing no inclusions visible to the unaided eye, and it exhibits intense color saturation with a strong, concentrated green face up. The polish is described as excellent, indicating a finely executed lap across crown and pavilion facets, and the overall symmetry of the facet junctions has been controlled to present uniform brilliance from all three apexes. The sapphire is responsibly sourced from Madagascar, and its medium table and well proportioned crown height maintain a lively interplay of brilliance and color, characteristic of high quality corundum faceting in this weight class.

The trillion faceting pattern used for this sapphire is a modified brilliant triangulation, with precise crown facet geometry to maximize dispersion and pavilion angles calibrated to the stone dimensions. The truncated corners and balanced girdle profile reduce chipping risk at the apexes while maintaining an aggressive light return. The excellent polish enhances facet crispness, producing defined flashes of white light and saturated color zoning that read as a deep green under both direct and diffuse illumination. The setting is engineered to complement the stone geometry, using a three prong cathedral-style basket that secures each apex while exposing the pavilion to light through an open gallery. The prongs are tapered and burnished to the sapphire girdle, minimizing metal intrusion into the visible table area and optimizing face-up color. The shank is executed in solid high-quality silver, with a gently rounded inner profile for comfort and a highly polished external finish to reflect light back into the sapphire. All junctions have been filed and hand-polished to remove stress points, a craftsmanship detail that preserves the integrity of the mount and reduces wear to the setting and the stone.

Ethical sourcing and traceability are fundamental to The Natural Sapphire Company commitment, and this piece exemplifies that policy. The sapphire originates in Madagascar and is procured through vetted supply channels that maintain documented chain of custody from mine to cutting workshop. Our sourcing protocol includes supplier audits, verification of fair labor practices, and engagement with local communities to support responsible mining techniques and environmental stewardship. We require transparent disclosure of any known treatments and provide access to gemological documentation when available, so technical buyers can evaluate origin, any enhancement history, and the results of clarity and color assessment. The Natural Sapphire Company also implements selective purchasing to avoid sources linked to conflict or exploitative labor, and we favor cutters and polishers who adhere to controlled waste management and water use practices, thereby reducing the environmental footprint associated with bringing this material to market.

For collectors and technically minded clients, this ring offers a combination of measured gemological performance and conscientious manufacture. The 0.70 carat trillion green sapphire presents a stable pavilion to crown ratio and clean facet junctions, making it suitable for daily wear when mounted in a securely engineered three prong setting. Silver has been chosen for its optical compatibility with the intense green saturation, producing a cool white backdrop that enhances perceived color depth. Because silver is more malleable than platinum or gold, routine maintenance is recommended, including periodic professional polishing and inspection of prong tightness, and avoidance of harsh chemicals to preserve the high polish finish. The Natural Sapphire Company provides full documentation on request, including provenance information and any available laboratory reports, and offers bespoke adjustments to mounting or metal choice for clients seeking alternative alloys or additional fabrication tolerances. If you require measured facet diagrams, detailed photomicrographs, or a discussion of the stone s optical behavior under varying light sources, our gemology team is available to supply the technical information needed to evaluate this ring to your exacting standards.
