0.80 Ct. Spinel from Ceylon (Sri Lanka)

This report presents a single, transparent spinel offered by The Natural Gemstone Company, described with precise gemological details to assist in informed selection. The stone weighs 0.80 carat and is fashioned into an elegant oval shape that measures 6.43 by 5.07 by 3.39 millimeters. Its hue is a purplish pink, with an intense color intensity that remains evenly distributed across the table and pavilion when viewed under standard lighting. The gem has been evaluated as eye clean at typical viewing distances, it exhibits excellent polish, and it is untreated, with no enhancement reported. The material origin is Ceylon Sri Lanka, a well regarded source for spinel that frequently yields saturated, transparent examples suitable for fine jewelry.

The cutting style is a mixed brilliant cut, a deliberate geometry that combines a brilliant facet arrangement on the crown with a coordinated set of pavilion facets. This configuration is designed to maximize internal light travel and controlled return to the eye. The proportional relationship of the crown angle, pavilion depth, and table aperture has been set to balance color saturation with lively return. The measured proportions translate to a depth that is approximately fifty nine percent of the average girdle diameter, a parameter that helps preserve the stone body color while permitting effective internal reflection. The faceting pattern is geometric and precisely executed, creating a network of small mirror planes that disperse light into tight flashes and softer, broader reflections, depending on viewing angle and illumination.

The optical behavior of this spinel demonstrates the benefits of its facet architecture. Under direct light the mixed brilliant geometry yields concentrated scintillation from the crown, coupled with broader flashes from the pavilion facets, producing an appearance that alternates between sparkling brilliance and an even wash of color. The purplish pink tones are intensified by the depth and pavilion geometry, and the excellent polish enhances the purity of each facet plane, allowing crisp facet junctions and minimal light leakage. Clarity at the eye clean grade ensures that the light paths through the gem remain unobstructed by visible inclusions, which preserves the contrast pattern and contributes to a clean, lively face up presentation.

From a practical perspective this 0.80 carat oval spinel is well suited to a range of settings, including solitaire rings, bezel set pendants, and more refined halo or channel mountings where the gem will benefit from secure support and targeted lighting. Spinel is a durable gemstone with good toughness and stability for everyday wear, and the present specimen combines durability with an elevated optical performance due to its careful cutting and finishing. The Natural Gemstone Company confirms the no enhancement status and origin as Ceylon Sri Lanka, and provides detailed measurements, grading notes, and photographic documentation to assist with selection and setting. For those seeking a naturally colored, precisely faceted spinel that emphasizes geometric faceting for maximum light play, this stone is a representative example suitable for both bespoke and classic jewelry designs.
