0.82 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 0.82 carat round blue sapphire measures 5.64 x 5.64 x 3.27 mm, and presents a refined mixed brilliant cut that balances scintillation and depth of color. The mixed brilliant faceting combines a well defined brilliant facet pattern on the crown with a tailored pavilion layout, resulting in a stone that returns light with controlled flashes and a pleasing overall brightness. The cutting proportions have been executed to preserve weight while maintaining optical performance, with a moderate table area relative to diameter and a pavilion depth that supports internal reflection without creating excessive windowing. The polish is excellent, producing crisp facet planes and sharp facet junctions that maximize contrast and highlight the cut geometry. This gem has not been subjected to any enhancement, and its natural origin in Ceylon Sri Lanka contributes to both its character and collector value.

On a technical level, the mixed brilliant cut of this stone emphasizes a round outline with a faceting scheme that optimizes both brilliance and color distribution. The crown exhibits precise star and kite facets that form a symmetrical pattern around the table, creating defined scintillation when the stone is tilted. The pavilion configuration has been calibrated to redirect light through the crown facets, achieving balanced return and a lively face up appearance. The girdle thickness has been controlled to facilitate secure setting and minimal metal intrusion, and the culet is proportioned to avoid light leakage while preserving a clean visual presentation from the top view. Craftsmanship notes include consistent facet alignment, symmetrical crown and pavilion intersection, and the absence of excessive facet graining, all indicative of skilled cutting and finishing practices.

Color and clarity characteristics are important determinants of this sapphires visual appeal and gemological merit. The stone shows a light blue intensity with cool undertones, a tonal range typical of fine Ceylon material that favors translucency and delicate color nuance over saturation. The color is evenly distributed across the crown and pavilion, allowing uniform appearance in a variety of mounting styles. Clarity is graded as very very slightly included, evaluated at eye level, which for practical purposes yields an eye clean presentation. Under magnification the stone reveals minute natural inclusions that do not obstruct the passage of light or detract from brilliance. These subtle internal features confirm the natural origin and provide a fingerprint of authenticity, while the complete absence of heat or other enhancements preserves the original crystal lattice and associated light behavior.

This sapphire is presented by The Natural Sapphire Company as a versatile collector grade stone that can function as a refined center for a bespoke ring, a classic solitaire pendant, or as part of a delicate multi stone composition. Its combination of a precise mixed brilliant cut, excellent polish, natural Ceylon provenance, and lack of enhancement results in a gem that reads as sophisticated and technically well executed when examined by knowledgeable buyers. The cut strategy produces a distinct play between pinpoint brilliance and broader light return, enabling the gem to act as a focal point in any setting while retaining the subtle, cool blue that connoisseurs of Sri Lankan sapphires appreciate. For those seeking a natural, technically refined sapphire to anchor a custom design or to elevate a curated collection, this stone offers both measurable gemological qualities and a compelling visual presence.
