1.30 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.30 carat blue sapphire from Ceylon Sri Lanka is a rare and elegant example of fine natural material, presented in a precise asscher octagon shape that measures 5.85 x 5.71 x 3.90 mm, and finished with an excellent polish. The asscher cut is traditionally associated with step cutting and an emphasis on clarity and internal depth, and here it has been tailored to maximize the stone s characteristic transparency and intense color intensity. There has been no enhancement to this sapphire, which means you are receiving an untreated gemstone in its natural state, a quality that collectors and informed buyers prize. At The Natural Sapphire Company we highlight both the objective gemological details and the visual character of each stone, so you know exactly what you are investing in.

From a grading perspective this sapphire displays a clarity grade of very very slightly included evaluated at eye level, a grade that tells an educated buyer that the gem is essentially eye clean with only minute natural features visible on careful inspection without magnification. The overall transparency is excellent, and the intense color intensity is evenly distributed across the pavilion and crown, allowing the asscher faceting to generate clean, architectural light play rather than the heavy scattering seen in more included or heavily treated material. The proportions of 5.85 x 5.71 x 3.90 mm produce a balanced table and pavilion depth that maintain strong light return, a distinct advantage of an expertly executed asscher cut in a sapphire of this size. The excellent polish further contributes to crisp facet junctions and a lively surface that resists dulling, so the stone sits bright and lively even under softer, ambient lighting.

What gives this sapphire its unmistakable signature are the natural inclusions and growth features that tell the story of its formation deep within the earth, and which also contribute to the gem s individuality in a way that synthetic or heavily treated sapphires cannot replicate. This stone exhibits a delicate network of fine silk and pinpoint crystals that are oriented in a pattern consistent with Ceylonese growth zoning, and faint internal growth planes that follow the octagonal geometry of the asscher cut. These inclusions are microscopic and non detracting to the naked eye, yet they produce a subtle silky sheen when the gem is tilted, creating a soft, velvety depth to the blue that changes with movement. In certain lighting the aligned silk and tiny crystals catch the light and form a gentle halo around the table, a signature effect that many connoisseurs describe as floral or star like, and which becomes a unique identifying characteristic for this particular sapphire. For the informed buyer these natural features are not flaws but verification of provenance and authenticity, adding narrative and rarity to the gem.

For use in fine jewelry this 1.30 carat asscher octagon sapphire lends itself beautifully to both classic and contemporary settings, where the clean geometric lines of the asscher cut can be complemented by simple prong work or an architectural bezel that echoes the stone s shape. Its dimensions and eye clean appearance make it ideal for a solitaire ring, a refined pendant, or as the centerpiece in a bespoke design that celebrates the stone s natural character. Because this sapphire is untreated and originates in Ceylon Sri Lanka, it carries a market appeal that blends historic prestige with modern ethical preferences, and it is a gemstone that will continue to reward the wearer with subtle shifts of color and internal life over a lifetime. At The Natural Sapphire Company we provide detailed imagery and gemological information so that each purchase can be made with confidence, and we are available to advise on settings and care that preserve the stone s natural beauty for generations.
