0.81 Ct. Yellowish Green Sapphire from Madagascar

This transparent yellowish green sapphire weighs 0.81 carat, with precise dimensions of 5.54 x 5.58 x 3.15 mm. The stone is cut in a round shape with a mixed brilliant facet arrangement, producing a balanced combination of table brilliance and pavilion scintillation. Clarity is graded as very very slightly included, evaluated at eye level, indicating that inclusions are minimal and do not detract from the gems visual performance in typical viewing conditions. Color is described as medium intensity, presenting a clear and even distribution of yellow and green tones across the face of the stone, and the polish is graded excellent, contributing to strong light return and a clean, reflective surface. Enhancement testing indicates no enhancement, and the gem is sourced from Madagascar, a locality known for producing sapphires with distinct and attractive color ranges.

The round shape and the near equal measurements of 5.54 by 5.58 mm make this sapphire especially well suited for custom jewelry projects, because the dimensions align closely with common standardized settings and allow precise bezel or prong seats to be prepared with minimal alteration. With a depth of 3.15 mm, the pavilion proportions translate to an overall depth near industry preferred ranges for mixed cut rounds, providing reliable face up presence without excessive pavilion material. These proportions allow the gem to serve effectively as a delicate center stone in a refined solitaire ring, a bright focal point within a halo, or as a paired element in stud earrings or a three stone design. The modest size and round outline facilitate symmetric mounting and ease of setting for custom designers, enabling predictable metal usage and stone retention strategies when fabricating prong, bezel, or channel assemblies.

From a performance and durability perspective, the mixed brilliant cut yields a pleasing interplay of larger table facets and smaller crown facets, which together enhance scintillation and deliver a lively appearance under a range of lighting conditions. The medium color intensity ensures the stone reads as distinctively yellowish green without overpowering adjacent metals or accent stones, making it adaptable to both warm yellow gold and cooler white metals depending on design intent. The very very slightly included clarity grade means internal features are not visually intrusive at normal viewing distances, and the excellent polish supports clean facet junctions and crisp light reflection. As a corundum species, sapphire is inherently hard and suitable for everyday wear when set correctly, and the stone benefits from a secure setting strategy that protects the girdle and pavilion without compromising the face up presentation.

The Natural Sapphire Company provides this untreated Madagascar sapphire as a material option for bespoke pieces where natural color and precise proportions are priorities, and where documented no enhancement status is required by the client. The stone is well suited to projects that call for accurate CAD modeling and tight tolerance metalwork, because its exact dimensions and round geometry translate directly into predictable seat profiles and consistent prong engagement. Photographic references showing the gem in hand and under tweezers illustrate scale and orientation for design planning, while the stones characteristics support a range of stylistic directions from minimalist solitaires to intricate multi stone arrangements.
