0.87 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.87 carat round blue sapphire presents exceptional gemological attributes that will appeal to discerning buyers, and it is offered by The Natural Sapphire Company. The stone measures 5.97 by 6.01 by 3.03 millimetres, yielding an average diameter of approximately 5.99 millimetres and a depth of approximately fifty point six percent. The round outline is precisely executed, with symmetry within trade tolerance and a mixed brilliant cut that combines a brilliant facet schema on the crown with a modified pavilion geometry. This mixed approach concentrates the table and star facets to optimize scintillation, while the pavilion facets are arranged to return color rich light rather than wash it out. The excellent polish indicates that facet junctions are sharp, facet planes are smooth, and there are no surface abrasions that would weaken light return or reduce longevity. These technical proportions and finishing standards result in a sapphire that balances lively brilliance with saturated color.

Color and clarity are the most important determinants of a sapphires presence, and this specimen exhibits vivid color intensity and a clarity grade assessed as very very slightly included, evaluated at eye level. Vivid intensity in a Ceylon origin stone means the blue is lively and saturated without veering into overly dark tones, retaining the characteristic luminous, almost cornflower blue that Sri Lankan material is prized for. The very very slightly included assessment denotes that inclusions are minimal and do not detract from the visual face up performance at normal viewing distances, and in practical terms this ensures excellent transparency and strong light transmission. Ceylon sapphires often exhibit attractive pleochroic variation with slightly different blue values when observed from different orientations, and the mixed brilliant cut here is tailored to manage pleochroism so that the gem reads uniformly blue in a range of settings. The stone has been heat treated, a standard and stable enhancement for sapphire that improves color saturation and can reduce the visibility of microscopic inclusions, and such treatment is industry accepted when disclosed.

From a setting and jewellery engineering perspective this sapphire is ideal for a finely crafted, durable jewel that will survive generations of wear. Corundum ranks nine on the Mohs scale, providing excellent resistance to abrasion, and when combined with secure setting techniques such as bezel, flush, or low profile four prong settings in platinum or high karat gold, the sapphire will resist mechanical risk over time. The round mixed brilliant form is inherently versatile, allowing traditional solitaire engagement settings, bezel set pendants designed for daily wear, or intricate vintage inspired designs where the stone can be the focal point amid hand engraved shoulders and hallmarked metal. To preserve the technical integrity of the stone, The Natural Sapphire Company recommends precision bezel wiring or reinforced prong shoulders executed by a master setter, tight seat tolerances, and a subtle protective profile above the gallery to minimize catch and wear during routine use.

A gemstone chosen with these specifications is an excellent candidate to become a generational heirloom, both for material durability and for enduring aesthetic appeal. The combination of vivid, classic Ceylon blue, high clarity, and precise mixed brilliant cutting means the stone will remain visually compelling as styles evolve. Proper documentation, including origin disclosure, treatment disclosure, gemological reporting, and a condition record created at the time of setting, will create provenance that enhances sentimental and monetary value for descendants. When set into a thoughtfully designed mounting that can be resized or modified without damaging the stone, this sapphire can be reinterpreted across generations, migrating from an engagement ring to a pendant or brooch, while retaining its technical virtues. The Natural Sapphire Company can advise on archival grade settings, period style options, and maintenance schedules that ensure this 0.87 carat Ceylon blue sapphire endures as a treasured family heirloom.
