1.67 Ct. Spinel from Burma (Myanmar)

This GIA certified spinel presents as a transparent, bluish green cushion shape weighing 1.67 carats, with dimensions of 6.88 by 6.07 by 5.00 mm. The gemstone is natural and untreated, originating from Burma, and it carries an eye clean clarity grade when evaluated at eye level, reflecting a high standard of clarity without significant inclusions visible to the unaided eye. The color intensity is described as intense, exhibiting a rich, saturated bluish green tone that remains stable across viewing angles. The finish is an excellent polish, which complements both the cutting style and the inherent optical qualities of the material. The stone has no enhancement, offering a completely natural color and appearance that is documented by GIA certification, providing reliable provenance and gemological confirmation.

The most distinctive element of this spinel is its checkerboard cut applied to the cushion outline, a cutting style that deliberately divides the crown surface into a grid of small, flat facets in a tessellated arrangement. This geometry increases the number of reflective planes on the crown, producing a complex interplay of specular highlights and internal flashes as light enters and exits the gem. The cushion shape, with its softened square outline and gently rounded corners, allows the checkerboard facet pattern to cascade smoothly toward the girdle, while the measured pavilion depth of 5.00 mm balances internal reflection with color saturation. The cumulative effect is an elevated scintillation that appears as a mosaic of light when the stone is moved, and a restrained brilliance that maintains depth of color rather than washing it out. The checkerboard array also diffuses concentrated light return, reducing the visibility of any localized color zoning and evenly distributing luminous reflections across the table. The excellent polish enhances each tiny facet, minimizing surface scattering and enabling crisp mirror like returns that accentuate the spinel s natural refractive response.

From a practical perspective this spinel combines desirable optical performance with the durability and day to day suitability that spinel is known for, making it appropriate for a variety of jewelry applications where sustained wear is expected. The intense bluish green color and checkerboard scintillation lend themselves to settings that allow light to interact with the stone from multiple directions, such as open prong mounts, halo styles with complementary gems, or bezel variants that still expose the crown to ambient illumination. Because the gemstone is unenhanced and GIA certified, the piece serves both as an aesthetic center and as a verifiable collector quality specimen, offering assurance of origin and treatment status.
