1.50 Ct. Greyish Violet Spinel from Ceylon (Sri Lanka)

This transparent 1.50 carat round greyish violet spinel measures 6.74 by 6.73 by 4.76 mm, cut in a faceted mixed brilliant style, clarity grade slightly included as evaluated at eye level, medium color intensity, and an excellent polish. Origin is Ceylon Sri Lanka, with no enhancement reported. The mixed brilliant execution pairs a finely proportioned brilliant crown with a complementary pavilion geometry, producing a controlled balance between brilliance and body color. The compact depth of 4.76 mm relative to the near equal table diameter and girdle span maintains optimal internal reflection pathways, allowing the greyish violet hue to present with even saturation across the table while preserving lively facet contrast. Slight inclusions are limited to features visible only at specific angles, and the high degree of transparency enables those internal characteristics to remain unobtrusive to overall light performance.

Technically, the mixed brilliant cut enhances spinel light return by combining small, precisely angled crown facets that break light into scintillation, with larger pavilion facets that act as efficient return mirrors, channeling light back through the table and crown. The result is a dynamic interplay of pinpoint flashes and broader face up brightness, with the medium color intensity benefiting from the pavilion geometry that deepens tone without extinguishing sparkle. Excellent polish reduces surface scattering, preserving sharp facet junctions and maximizing luster, while the faceting symmetry ensures uniform facet reflection and minimal light leakage through the girdle. In practical terms, this means the gem exhibits a crisp, lively brilliance when viewed face up, while maintaining a rich, consistent greyish violet body color under varied lighting. As an additional product detail, the opal type listed alongside our offerings is White Opal, noted for its pale body tone and subtle play of color, which contrasts with the stable, saturated presentation of this spinel. The Natural Gemstone Company stands behind the provenance and craftsmanship of this Ceylon spinel, offering a gem that showcases considered cutting strategy, precise polish, and natural, unenhanced material quality.
