1.48 Ct. Greyish Blue Spinel from Ceylon (Sri Lanka)

The Natural Gemstone Company presents a transparent, certified Other certified Gray 1.48 carat oval greyish blue spinel, dimensions 7.65 by 6.60 by 4.15 millimeters, faceted and finished with a mixed brilliant cut. This spinel displays a medium color intensity, a clarity grade described as very slightly included when evaluated at eye level, and an excellent polish. There has been no enhancement applied to the stone, and its natural color is a direct expression of its material origin, Ceylon Sri Lanka. The oval outline and proportionate dimensions create a balanced visual presence, suitable for a variety of settings where both color and optical performance are valued. The supplied certification reflects the described qualities and confirms the absence of clarity or color treatments, providing transparent documentation for collectors and designers.

The mixed brilliant cutting style has been selected to optimize the interaction between the spinel s intrinsic optical properties and the observer s perception of light, color, and scintillation. In this oval, the cutter has combined the light concentrating advantages of brilliant type facets on the crown with carefully arranged pavilion facets that control light return, producing a lively display of brilliance across the table and facets. The depth of the stone at 4.15 millimeters corresponds to an overall depth proportion of approximately 58 percent relative to the mean diameter, a proportion that supports efficient internal reflection while preserving face up spread. The result is even distribution of reflected light, with crown facets diffusing incident light to reveal the greyish blue hue, while pavilion facets redirect light back through the table to enhance perceived brightness. The very slightly included clarity grade means that inclusions are minor and unobtrusive at typical viewing distances, and they do not interrupt the engineered pathways of light through the stone. Excellent polish further minimizes surface scattering and ensures facet junctions remain crisp, contributing to crisp facet contrast and controlled scintillation with every movement.

Beyond the immediate visual performance, the cutting decisions employed in this oval spinel respect the material s refractive and dispersive properties, allowing the gem to display color and brilliance in a stable and predictable manner. Spinel s refractive index and modest dispersion respond well to a mixed brilliant layout, where smaller, well aligned facets produce a combination of lively sparkle and clear color presentation rather than excessive fire that would narrow the perceived tone. The cutter s attention to symmetry and table size produces consistent mirror like flashes and an even pattern of light return across the face of the gem, which is particularly important in an oval where slight asymmetries can lead to uneven brightness or a windowed appearance. The durable nature of spinel, combined with the stone s no enhancement status, makes this gem appropriate for daily wear in rings or for application in necklaces and earrings where long term polish retention and stable color are desirable. For professional buyers and connoisseurs seeking a specimen from a noted locality, The Natural Gemstone Company s documentation of origin and the stone s uncompromised finishing detail support confident selection and integration into refined jewelry design.
