0.66 Ct. Green Sapphire from Madagascar

This transparent green sapphire weighs zero point six six carat, and is presented in a classic round outline with precise dimensions of five point zero four by five point zero five by three point two nine millimeters. The stone is fashioned in a mixed brilliant cut, a facet architecture that combines a brilliant style crown with a modified pavilion to balance spectral dispersion and color saturation. The cut geometry yields a depth ratio of approximately sixty five percent, a proportion that promotes robust return of light from the pavilion while maintaining a broad table for stable face up color. The medium color intensity reads as a fresh green with subtle yellow undertones under daylight, and the combination of crown angles and pavilion modifications produces focused scintillation with balanced flash and broad color zones rather than excessive sparkle that would wash the hue.

Clarity is graded as very very slightly included when evaluated at eye level, indicating that the gem is effectively eye clean, and that the inclusions are minute, confined to internal growth features that do not interrupt the path of light through the pavilion. These inclusions are sometimes useful as fingerprint details for provenance, but they remain unobtrusive to visual performance. The polish is excellent, the facet junctions are crisp, and the facet symmetry has been executed with attention to optical return, which enhances both brilliance and scintillation. Equally important for discerning buyers, this sapphire has received no enhancement, so the color and clarity are natural and stable. For collectors who prioritize untreated material, a naturally colored sapphire of this size and finish is an appealing option.

Sourced from Madagascar, this sapphire is supplied through The Natural Sapphire Company supply chain, which emphasizes traceability and responsible procurement practices. Our sourcing partners operate with attention to environmental stewardship at mine sites and to fair labor practices among artisanal and small scale mining communities. We engage with local stakeholders to promote improved mining techniques, reclamation where feasible, and equitable compensation models, and we maintain documentation of the origin and handling of each parcel. The absence of treatment further simplifies provenance claims, because color and clarity are intrinsic attributes rather than the result of laboratory intervention. For conscious consumers who weigh the ethics of extraction as heavily as gem quality, the combination of documented Malagasy origin, untreated material, and transparent supply chain oversight aligns with a responsible purchasing philosophy.

In terms of wearable design and long term value, the corundum hardness of nine makes this gem resilient for daily wear in settings that protect the girdle, and the modest zero point six six carat weight and five millimeter diameter make it ideal for refined, minimalist applications. Designers may choose a low profile prong or bezel mounting to showcase the mixed brilliant crown and to allow light to enter the pavilion, sustaining the lively yet controlled scintillation. The natural medium green tone complements both warm and cool metals, and it is particularly effective as a solitary accent in engagement rings, as a center for delicate halos, or as an accent stone that introduces a quiet color statement. At The Natural Sapphire Company we offer high resolution imagery and can provide independent laboratory documentation upon request, enabling an informed evaluation of the gem before incorporation into a bespoke setting or into a curated collection for the mindful buyer.
