0.93 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exquisite transparent 0.93 carat round blue sapphire measures 6.01 by 6.03 by 3.52 millimeters, and is expertly fashioned in a mixed brilliant cut that balances table brilliance with scintillation through the pavilion facets. The clarity is described as very very slightly included evaluated at eye level, which to an informed buyer indicates eye clean appearance and minimal internal features that do not detract from the gem face up. The color is medium intensity, presenting a lively blue that leans slightly toward a cool to slightly violet blue depending on lighting, and the polish is graded excellent, producing crisp facet junctions and bright reflections. This sapphire has been heat treated, a common and stable enhancement applied to improve color and clarity, and its documented origin is Ceylon Sri Lanka, a provenance that carries both historical and market significance. At this size and in a round mixed brilliant cut, this sapphire offers optimal spread and wearable presence, making it ideal for a solitaire engagement ring or a refined stud setting where the stone can be appreciated in direct light.

From a gemological perspective the combination of medium color intensity, very very slightly included clarity at eye level, and an excellent polish yields a stone with lively face up color and strong return of light. The mixed brilliant cut is designed to maximize brilliance and conceal modest inclusions, while the slightly less deep pavilion depth allows for a pleasing table view and good spread for a 0.93 carat weight. When comparing hue and tone to gemstones from other famous locations, Ceylon sapphires typically exhibit a brighter, more lively blue often with a hint of violet or cornflower blue that sits at medium to medium light tone, and that is exactly the character of this piece. By contrast, Kashmir sapphires are renowned for their velvety cornflower blue with a soft, slightly darker tone and a unique silkiness that comes from dense rutile inclusions, while classic Burmese or Myanmar sapphires often show a deeper royal blue with stronger saturation and a slightly darker tone. Madagascar stones can vary broadly, but many produce vivid saturated blues similar to Burmese material, while Thai and Australian sapphires more often present a darker, inky tone with less optical brightness.

For the educated buyer the appeal of this Ceylon sapphire lies in the balance between color, clarity, cut, and provenance. The medium intensity blue with a cool violet tendency is highly desirable for those who prefer a lively, luminous blue rather than a very dark, inky tone. The clarity described as very very slightly included evaluated at eye level effectively means excellent eye clean appearance and contributes positively to light performance, while the excellent polish ensures maximum scintillation. Heat treatment in sapphires is widely accepted in the trade when fully disclosed, and it improves color uniformity and stability without compromising the gem’s natural origin, making a heat treated Ceylon sapphire a transparent and sensible choice for collectors and jewelry designers alike. When considering value, Ceylon origin often commands a premium relative to generic sources because of the historical reputation for bright, attractive blues, yet it normally sits at a more accessible price point than top tier Kashmir or fine Burmese material, making this stone a smart acquisition for someone looking for quality and provenance without the extreme premiums of the rarest sources.

When selecting a setting and considering the long term enjoyment of this stone, the round mixed brilliant cut makes it versatile and flattering in many designs, from classic four prong solitaires to more modern bezel or tension settings that emphasize color and profile. Its near one carat weight and 6.01 by 6.03 millimeter dimensions provide a pleasing finger presence without appearing oversized, and it photographs beautifully as shown in the accompanying images. Care for a heat treated sapphire is straightforward, basic precautions against harsh knocks and strong chemical exposure are recommended, and routine cleaning with warm soapy water and a soft brush preserves brilliance. At The Natural Sapphire Company we document origin when it is available, and we maintain full disclosure on treatments, so buyers can confidently evaluate the stone against other important examples. In direct comparison to other famous origins, this Ceylon example shows the characteristic bright medium blue tone that is lighter and more lively than the deeper Kashmiri and Burmese blues, and it is more vividly blue and less inky than many Thai or Australian stones, making it an excellent choice for anyone seeking the distinct Ceylonic character in a clean, well cut, and wearable gem.
