1.51 Ct. Spinel from Ceylon (Sri Lanka)

One transparent 1.51 carat pear shape greyish blue spinel is presented with precise measurements of 8.63 by 6.56 by 4.07 mm, a mixed brilliant cut, and an excellent polish. The gem is natural, originating from Ceylon Sri Lanka, and it has received a clarity grade of slightly included as evaluated at eye level. Color intensity is classified as medium, and no enhancement has been applied to alter or improve the stone. The Natural Gemstone Company provides this description to offer clear and factual information for appraisal, consideration, and selection, and to confirm that the stone is offered in its natural state without heat treatment or other modifications.

The combination of color and size found in this specimen is uncommon when compared to the broader population of spinels available in the market. Spinel deposits commonly yield red and pink material, and blue spinel occurrences are notably rarer, particularly when the hue carries a greyish component that moderates the blue toward a more subdued, sophisticated tone. At 1.51 carats this pear shape falls into a size range that is meaningful for both collectors and designers, while the greyish blue coloration at medium intensity is not frequently encountered at this weight. When assessing rarity it is useful to consider both absolute weight and the specific hue, and in that context this spinel occupies a position of comparative scarcity relative to typical spinel offerings in retail and wholesale channels.

The mixed brilliant cut has been executed to optimize light return along the pear shape outline, and the excellent polish enhances surface brightness and contrast from facet junction to facet junction. The clarity grade of slightly included indicates the presence of minor internal features, and at eye level those features do not substantially interfere with transparency or the gem response to light. The proportions of 8.63 by 6.56 by 4.07 mm yield a balanced silhouette suitable for a variety of mounting styles, and the apex to base depth produces pleasing scintillation without appearing shallow or over deep. Because no enhancement has been applied, the optical characteristics reflect the original crystallographic and chromophore distribution, which contributes to the stone character and ensures predictable long term stability when set and worn.

For design and practical use this spinel is well suited to engagement rings, solitaire pendants, and bespoke fine jewelry where a measured presence is preferred over more dominant sizes. The Natural Gemstone Company recommends secure settings that support the pointed end of the pear shape and protect against impact at the girdle, and suggests consultation with a jeweler experienced in working with medium sized spinels to optimize setting height and prong placement. Documentation of origin from Ceylon Sri Lanka and confirmation of no enhancement accompany the stone, and inquiries for additional images, light views, or appointment viewing are welcomed. This specimen will appeal to those seeking a naturally colored spinel with an uncommon greyish blue hue and a meaningful carat weight, offered with transparent description and provenance from The Natural Gemstone Company.
