1.99 Ct. Spinel from Ceylon (Sri Lanka)

This transparent 1.99 carat oval blue spinel presents precise proportions of 9.03 by 6.83 by 4.29 mm, a mixed brilliant cut, and a clarity grade assessed as very very slightly included at eye level. The gem shows a dark color intensity with consistently deep blue saturation typical of fine Ceylon spinel, and it is offered with no enhancement. The cut and polish are executed to an excellent standard, producing a clean face up appearance and even facet junctions. As a naturally durable gemstone with a robust crystalline structure, this spinel is well suited to everyday jewelry, and the absence of treatments preserves the stone’s original optical and physical properties as measured by our gemological team.

The geometric faceting of this mixed brilliant oval has been designed to optimize light performance by balancing brilliant crown geometry with a carefully proportioned pavilion. The crown facets are arranged to capture and redirect incident light into the pavilion, while the pavilion facets are angled and sized to return that light as controlled brilliance and scintillation. The oval outline elongates the visual table area, enhancing the perception of size, while internal facet symmetry promotes orderly reflections that reveal flashes of blue rather than chaotic shimmer. The result is a measured interplay of light and dark, where strong contrast facets enhance depth and the dark color intensity stabilizes the blue tone, allowing small, bright flashes to become legible against the darker body color. The overall effect is purposeful, with geometric precision delivering maximum light play within the constraints of the stone’s natural color and clarity.

For setting and design considerations the 4.29 mm depth and mixed brilliant proportions make this oval spinel versatile, and it will sit attractively in traditional prong settings that allow unobstructed light entry from the crown. A low profile bezel may protect the girdle while maintaining a bold face up presence, and open back settings can be used when additional light return is desired. The gem’s very very slightly included clarity supports fine jewelry mounting without the need for concealment, and the excellent polish minimizes surface diffusion of light for sharper reflections. This example from The Natural Gemstone Company has been selected and evaluated for its cut quality, natural origin from Ceylon, and lack of enhancement, and it is accompanied by our internal assessment of optical performance. Recommended care includes gentle cleaning with mild soap and a soft brush, avoiding harsh acids or ultrasonic exposure to protect the polished facets and preserve the stone’s long term brilliance.
