0.93 Ct. Violet Spinel from Ceylon (Sri Lanka)

This 0.93 carat oval violet spinel presents a precise marriage of proportion and optical performance, engineered to showcase natural color with maximum brilliance, The gem measures 7.00 by 5.32 by 3.33 millimeters, yielding an overall depth that is approximately 54 percent relative to the mean of its length and width, The cutting style is faceted with a mixed brilliant design, combining a brilliant cut crown with a complementary pavilion arrangement to optimize both return of light and retention of color, Clarity is graded as very slightly included when evaluated at eye level, transparency is excellent, polish is graded as excellent, and no enhancement has been applied, The origin is Ceylon Sri Lanka, a source long admired for producing spinels with saturated hues and clean crystal material, The Natural Gemstone Company offers this stone as an example of precise lapidary work and natural gem integrity.

The geometric faceting on this oval spinel is calibrated to allow maximum light play through a controlled interplay of facet planes, The mixed brilliant approach places concentric, kite shaped and triangular facets on the crown to disperse incident light into numerous return paths, while the pavilion facets are arranged to capture and redirect light toward the viewer, The result is strong overall brilliance, lively scintillation across small motion, and a balanced presentation of color saturation without dark windows or zones, Facet count on mixed brilliant ovals is typically around fifty eight facets, and in this specimen the cutter has applied a faceting scheme that preserves a well centered table and symmetrical facet junctions, This precise geometry mitigates the inherently modest dispersion of spinel, allowing the intense violet tone to remain vivid and dynamic rather than appearing flat or lifeless under varied lighting conditions.

From a gemological perspective, spinel is singly refractive and lacks the distinct pleochroism of some other species, which places the onus on faceting to produce color separation and sparkle, This violet spinel benefits from a refractive index in the expected range between 1.718 and 1.730, and a low dispersion value around 0.018, The cutter has compensated for the modest dispersion by optimizing crown height and pavilion angles to favor return of white light and localized flashes of color, The very slightly included clarity grade indicates that inclusions are minimal at normal viewing distance, They do not interfere with facet reflections or overall transparency, The excellent polish enhances facet crispness and minimizes light scatter at facet junctions, contributing to a clean, mirror like surface that accentuates each geometric plane.

Practical considerations for this 0.93 carat oval violet spinel include its robust wearability and natural state, Spinel rates eight on the Mohs hardness scale, offering excellent resistance to abrasion for everyday jewelry settings, The absence of enhancement confirms that the intense violet hue is wholly natural, and the Ceylon provenance confirms geological character and trace element chemistry consistent with the saturated tone, For customers seeking documentation, The Natural Gemstone Company can provide high resolution imaging, light performance analysis, and independent gemological certification upon request, Custom mounting and design services are available to ensure that the mixed brilliant faceting and oval geometry are presented to full advantage in a ring, pendant, or bespoke setting, We invite technical inquiries and are prepared to discuss facet schematics, proportion diagrams, and on request, plus and minus tolerances used by our cutter to achieve the optimal balance of brilliance and color in this exceptional Sri Lankan spinel.
