0.82 Ct. Purplish Blue Sapphire from Ceylon (Sri Lanka)

This transparent 0.82 carat oval purplish blue sapphire from Ceylon is a compact and lively example of classic Sri Lankan gemstone character, offered by The Natural Sapphire Company. The stone measures 6.08 x 4.15 x 3.65 mm, and it has been faceted in a mixed brilliant cut to balance scintillation and color concentration, creating a vivid face up appearance. Clarity is graded slightly included at eye level, which indicates that small natural inclusions are observable to a trained eye but do not detract from the overall transparency or the gem fluidity. The polish is excellent, which maximizes light return from the pavilion facets and sharpness from the crown facets, and the stone has undergone routine heat treatment, a long established and stable enhancement used to refine color and improve clarity in corundum while maintaining permanence under normal wear conditions. Buyers who value provenance will appreciate that this sapphire is from Sri Lanka, an origin renowned for producing lively, clear stones with bright blue to violet tonalities, and this specimen exemplifies that tradition in a wearable 0.82 carat size.

When compared to famous sapphires in history, this Ceylon gem occupies a unique place in the spectrum of collectible blues, offering attributes that appeal to educated collectors and connoisseurs. Whereas Kashmir sapphires are celebrated for their velvety cornflower blue and soft diffusion of light, and Burmese sapphires are often sought for their deep royal blue saturation, Ceylon examples like this one tend to favor a brighter, more brilliant expression of blue with a hint of violet that can be extremely attractive in smaller gems. Historic gems such as the Logan Sapphire and the Star of India underscore the range and prestige of Sri Lankan material, but those museum sized stones are valued for their exceptional scale and historical context. By contrast, this 0.82 carat oval offers the practical advantage of intense, vivid color in a size that works well for everyday jewelry, and it provides collectors with a taste of Ceylon character in a more accessible and wearable format. The purplish blue hue is a subtle and desirable variation that sits between the pure cornflower and the deeper royal tones, giving it a versatile aesthetic that is at once classical and distinct.

For the technically minded buyer, there are several points that reinforce the gem quality and suitability for fine jewelry. Corundum, the species that includes sapphire, has a refractive index around 1.76 to 1.77 and a Mohs hardness of 9, which means this stone exhibits excellent durability for daily wear when set properly. The recorded dimensions yield a depth that is substantial relative to the gem face up spread, and that additional depth plays a role in intensifying the color, making the stone appear richer than a shallower counterpart of the same weight. The mixed brilliant cut was selected to enhance both brilliance and color concentration, which is particularly effective for an oval of this shape and size, and the excellent polish ensures crisp facet junctions and attractive light return. Slight inclusions are typical for natural sapphires and often provide internal character and fingerprint evidence of natural origin, they do not materially affect toughness in this specimen, and heat treatment is industry accepted and fully stable under normal use. The Natural Sapphire Company stands behind the authenticity and origin of its gems, and we can provide supporting documentation and advisory guidance on ideal settings, mounting choices, and care, whether you intend this purplish blue Ceylon sapphire for a solitaire engagement ring, a halo pendant, or a bespoke piece that emphasizes its vivid coloration.
