1.45 Ct. Blue Spinel from Ceylon (Sri Lanka)

This 1.45 carat oval blue spinel from Ceylon, supplied by The Natural Gemstone Company, combines measured proportions with a restrained elegance. The gem measures 7.56 by 6.18 by 3.80 millimeters and is fashioned in a mixed brilliant cut, an arrangement that balances a faceted crown with a pavillion designed for optimal light return. The stone is transparent, with a clarity grade evaluated as slightly included at eye level, and it is untreated, with no enhancement. Color is intense across the face up view, presenting a pure, even blue that remains vibrant under varied lighting conditions. The polish is excellent, producing clean facet junctions and a smooth surface that supports strong reflection and scintillation.

Although the clarity is graded as slightly included at eye level, the overall execution of cut and finish produces an appearance of visual perfection that enhances its beauty from every angle. The mixed brilliant facet architecture directs light into and back out of the table, while the excellent polish allows those returns to emerge as crisp flashes rather than blurred glows, minimizing the visual impact of minor internal features. The gem sits with pleasing symmetry and proportions, so side views reveal well controlled pavilion depth and consistent facet alignment, which together maintain uniform brilliance around the girdle. The transparency and intense color enable a deep, saturated face up that reads lively in both direct and diffused light, while the precise facet transitions create controlled scintillation with movement. The combination of durable spinel material, accurate cutting and professional finishing makes this stone suitable for a variety of mounting styles, including solitaire and halo settings, where the optical performance can be fully appreciated. For collectors and designers seeking an untreated, well cut blue spinel with consistent color and refined light performance, this example from The Natural Gemstone Company demonstrates how careful lapidary work can render a gem that appears flawless in presentation, offering balanced color, coherent brilliance, and pleasing proportions from every viewpoint.
