0.90 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This elegant pear shaped blue sapphire weighs 0.90 carat, and measures 8.17 by 4.97 by 3.10 millimeters, an ideal size for a refined solitaire or a halo engagement design. Cut to a mixed brilliant configuration, the gem presents a pleasing table and lively scintillation, combined with an excellent polish that delivers crisp facet junctions and strong light return. The color is medium in intensity, a true Ceylon blue with a delicate cool overtone that hints at slight violet, a tone commonly associated with Sri Lankan material, and the stone has been heat treated to optimize hue and clarity in a manner that is stable under normal wear. Clarity is graded as very very slightly included, evaluated at eye level, which in practical terms means the sapphire appears eye clean with only minute inclusions evident under magnification, an important factor for buyers seeking transparency and visual purity.

The proportions of this pear shaped sapphire favor a generous face up appearance, the length to width ratio of approximately 1.64 creating a classic teardrop silhouette that flatters a variety of mounting styles. The relatively shallow depth of 3.10 millimeters contributes to a broad table and an expansive face up presence for its 0.90 carat weight, making the stone appear larger when set, while the mixed brilliant facet arrangement balances color saturation and scintillation to produce animated light performance. Because the stone was cut with care to maximize its visual spread and brilliance, subtle pleochroic effects may be observed as the sapphire is rotated, which can deepen the experience of its medium blue color under different lighting. The excellent polish enhances the overall brilliance and makes the gem exceptionally appealing when viewed both loose and in a finished setting.

On the Mohs hardness scale sapphires rate a nine, second only to diamond, which explains their long standing reputation for durability and suitability for everyday jewelry such as engagement rings. This high hardness makes sapphire highly resistant to scratches and abrasion from most materials encountered in daily life, and when set with appropriate protection for the pointed end of a pear shape, the stone is well suited for regular wear. Practical setting choices include a protective bezel or a secure V prong for the tip, and a classic three or five prong arrangement for the shoulders to minimize exposure to knocks. Heat treated sapphires are generally stable, and the enhancement applied to this stone is a widely accepted and permanent treatment under normal conditions, however abrupt thermal shock should be avoided, and routine maintenance such as cleaning with warm soapy water and a soft brush is advised. Professional ultrasonic or steam cleaning is usually safe for well cut and healed sapphires, but if you plan to have the stone set before such cleaning it is prudent to consult your jeweler about the specific setting and inclusions.
