1.30 Ct. Spinel from Ceylon (Sri Lanka)

This transparent 1.30 carat cushion violet spinel measures 6.59 by 6.26 by 4.35 mm, and is fashioned with a mixed brilliant cut that balances large pavilion facets with a stepped crown configuration for controlled light return. The color presents at medium intensity, a refined violet that remains neither deeply saturated nor pastel. Clarity is graded very slightly included, evaluated at eye level, with inclusions that are minute and do not disrupt visual performance. The polish is excellent, producing crisp facet junctions and mirror like facet surfaces. There has been no enhancement to the stone, and its documented origin is Ceylon Sri Lanka, a region known for producing naturally colored spinel with stable, attractive hues.

Under natural daylight and cool white LED lighting, the spinel displays a clear, lively appearance, with the mixed brilliant cut returning bright, white flashes that emphasize the stone's internal clarity. The medium color intensity benefits from neutral to cool light, producing a clean violet tone that reads true across the crown. Under warm incandescent lighting and candlelight, the violet takes on a slightly warmer aspect, appearing richer and more velvety, with broader flashes and a softer overall glow. In focused spot illumination, such as display or accent lighting, the facet geometry produces strong scintillation, alternating quick pinpoint flashes with broader flashes that outline the cushion silhouette. The combination of excellent polish and very slight inclusions means that light performance is dominated by facet architecture rather than internal features, maintaining both sparkle and depth across lighting environments.

This spinel's robustness and unenhanced status make it appropriate for fine jewellery where long term durability and natural color are priorities. At 1.30 carat and the stated dimensions it is well suited to a center stone in a ring or pendant, and the cushion silhouette complements a variety of mounting styles. The Natural Gemstone Company attests to the stone's described qualities, including cut, clarity, color intensity, and origin. For designers and collectors seeking a transparent, naturally colored violet spinel with consistent performance under varied lighting, this example represents a balanced combination of optical precision, natural color, and artisanal finish.
