0.45 Ct. Violet Spinel from Ceylon (Sri Lanka)

This 0.45 carat marquise violet spinel from Ceylon Sri Lanka is a study in precise cutting and natural color, presented by The Natural Gemstone Company. The stone measures 7.70 x 3.33 x 2.72 mm and is transparent, exhibiting a medium color intensity in a pure violet hue. The cutting style is faceted with a mixed brilliant cut, combining a brilliant crown with a step influenced pavilion to optimize both dispersion and focused light return. The marquise outline has carefully executed symmetry, controlled table proportions, and an appropriate pavilion depth that together create balanced face up proportions, strong central brilliance, and dynamic edge to tip performance. Clarity is graded very very slightly included when evaluated at eye level, the inclusions are minute and localized, and they do not detract from the optical performance. The polish is excellent, showing uninterrupted facet junctions and crisp facet planes, and the finishing demonstrates skillful lapidary work. The gem is natural with no enhancement, and the absence of treatments preserves its original refractive and absorptive properties.

Under different lighting conditions this violet spinel reveals distinct aspects of its optical personality, based on facet geometry and optical constants. In bright daylight with a high correlated color temperature, the mixed brilliant faceting disperses white light into sharp flashes of internal brilliance and reveals the medium color depth as a vivid violet that remains evenly distributed across the marquise. Diffuse lighting softens the contrast pattern, allowing the eye to appreciate the stone s body tone and the silky transition from crown to pavilion without overpowering sparkle. Under incandescent or warm LED illumination the stone displays enhanced warmth and a deeper violet saturation, with scintillation concentrated along the elongated facet planes and at the tips, producing lively contrast and visible flashes on movement. Under focused spotlighting the pavilion angles and facet alignment produce pinpoint flashes and distinct light return, enhancing the perception of fire and scintillation across the stone s surface. The mixed brilliant design ensures that face up brilliance and internal sparkle remain well balanced across a range of viewing conditions, making this marquise violet spinel a technically refined choice for connoisseurs who value precise cutting, natural origin, and uncompromised optical performance.
