2.30 Ct. Spinel from Ceylon (Sri Lanka)

One beautiful transparent 2.30 carat radiant shape blue spinel is now available from The Natural Gemstone Company, presented with precise dimensions of 8.88 x 6.59 x 4.10 mm. This stone exhibits a radiant cut that combines trimmed corners with a brilliant facet pattern, producing both scintillation and clean geometric lines. The clarity grade is eye clean, as evaluated at eye level by experienced graders, and the surface shows an excellent polish which maximizes light return from every facet. Color intensity is described as intense, a term that connotes a saturated and vivid blue body color that retains depth without appearing overly dark. Importantly for discerning buyers, this spinel has undergone no enhancement, supplying the natural integrity and transparency that collectors and custom jewelers prize, and the documented origin is Ceylon Sri Lanka, a source renowned for producing some of the world s most desirable blue spinels.

When evaluating quality for a purchase or a custom design project, specific grading points matter. The eye clean clarity grade indicates that there are no inclusions visible to the unaided eye at typical viewing distances, which is particularly valuable for a stone destined to be set as a focal point. The excellent polish minimizes surface milling and polishing lines, which in turn enhances both brilliance and the perceived sharpness of the radiant outline. Radiant cuts are engineered to balance brilliance and full body color, so the facet architecture here has been optimized to display the intense Ceylon blue without obscuring the stone s internal light path. From a gemological perspective, spinel is a stable and robust choice for jewelry, with a hardness of approximately eight on the Mohs scale and a refractive index that contributes to bright, lively light performance. The combination of transparency, saturated color, and superior cutting quality makes this stone technically and aesthetically attractive to an educated buyer seeking both beauty and durability.

This spinel s dimensions and shape make it especially well suited for custom jewelry. At 8.88 mm by 6.59 mm and 4.10 mm deep, the stone falls into a size range that offers presence without overwhelming a design, and the slightly elongated radiant outline produces an elegant silhouette that flatters many finger shapes when set in a ring. For an engagement ring or solitaire pendant, this size gives a strong central appearance while still allowing for complementary accents. The radiant cut s trimmed corners and mixed facet pattern accommodate both modern and vintage interpretations, from a clean solitaire with minimal metal to a halo design that emphasizes color contrast. Depth and table proportions are favorable for prong settings, which allow light to enter from multiple angles, and the excellent polish means that bezel settings will also present a polished surface without hiding the stone s inner fire. Designers often choose platinum or rich 18 karat gold to frame a Ceylon blue spinel, as these metals offer contrast and longevity while supporting secure settings for an eye clean, untreated center stone.

Beyond design flexibility, this spinel represents a strong long term value for a client seeking an ethical and natural gemstone source. Stones from Sri Lanka carry a documented and respected provenance that appeals to collectors and clients who care about origin and traceability. The absence of enhancement, combined with natural transparency and intense color, places this gem in a category that usually commands premium consideration among gem professionals. From a maintenance standpoint, the stone s inherent stability means it responds well to normal jewelry care, with cleaning recommended using warm water, mild detergent, and a soft brush, avoiding harsh chemicals and ultrasonic cleaners when in doubt about mounting integrity. For buyers interested in certification, we at The Natural Gemstone Company can assist in obtaining independent grading documentation and can advise on appraisal options for insurance and resale planning. Whether you are commissioning an engagement ring, a bespoke pendant, or a signature cocktail ring, this 2.30 carat radiant blue spinel offers a rare combination of size, shape, optical quality, and provenance that will sit confidently at the center of any custom design.
