0.88 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 0.88 carat cushion shape blue sapphire combines precise proportions and classic beauty, making it immediately appealing to an educated buyer. The gem measures 5.98 by 5.42 by 3.01 mm, and it has been finished with a mixed brilliant cut that balances scintillation with color depth. The clarity is graded as slightly included when evaluated at eye level, which indicates minor inclusions that do not compromise transparency or overall visual appeal. The color intensity is described as intense, a quality that is particularly desirable in Ceylon sapphires, and the polish is excellent, providing clean facet junctions and lively light return. Importantly this sapphire is natural and untreated, with no enhancement, and its origin is Ceylon Sri Lanka, a source known for producing some of the world most desirable blue sapphires. At The Natural Sapphire Company we present these facts so that informed clients can clearly understand the material qualities that contribute to both beauty and value.

Understanding the grading details helps explain why this stone carries a premium beyond its carat weight. Slightly included clarity at eye level means the stone remains visually transparent and bright in typical viewing conditions, while inclusions are minor and confined, preserving the integrity and durability of the gem. The intense color intensity in a Ceylon sapphire typically results from the mineral chemistry of corundum combined with trace elements, most notably iron and titanium, which produce a saturated blue that reads vividly under natural light. Ceylon sapphires are often prized for a lively medium to medium strong tone and for a blue that can present with an almost electric quality when well cut. The mixed brilliant cut used here is particularly effective for a cushion outline, because it maximizes fire and scintillation without sacrificing the stone apparent color, so the wearer experiences both sparkle and rich blue color, an attractive combination for collectors and for those commissioning bespoke pieces.

From the perspective of custom jewelry design this sapphire is exceptionally well suited due to its balance of size, shape and depth. At 0.88 carat and with a cushion outline that measures just under six millimeters by five and a half millimeters it occupies a versatile design niche, large enough to serve as a confident centre stone in a delicate ring, and small enough to work as a refined focal point in a pendant or as the central gem in a three stone composition. The depth of 3.01 mm provides enough pavilion to protect the crown facets while allowing for a variety of setting styles, including low profile bezels for daily wear, prong settings that emphasize light entry and sparkle, and halo designs that enhance perceived size without overwhelming the stone natural beauty. The mixed brilliant cut further supports design flexibility because the facet arrangement produces pronounced scintillation at close viewing distances, which is particularly desirable for engagement rings and wearable pieces where the gem is seen in both near and medium range encounters.

When sourcing a sapphire for a permanent custom commission provenance and treatment disclosure are central to long term value and collector confidence, and this stone meets those expectations. It is a natural Ceylon sapphire with no enhancement, and its excellent polish and measured dimensions are provided so that a jeweller can plan precise settings and metal choices with confidence. At The Natural Sapphire Company we ensure transparent documentation and careful photography so that clients and craftsmen can evaluate proportions, table size, and visual behavior under light before the work begins. For clients seeking a design consultation our team can advise on metal color and karat, prong structure and bezel profiles that protect corners while showing the cushion outline to best effect. This sapphire is an ideal candidate for a custom engagement ring where the combination of intense Ceylon blue, a durable corundum composition, and a thoughtful cut will result in a piece that performs for years, both in daily wear and as an heirloom that retains both emotional and market value.
