0.94 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 0.94 carat cushion shape blue sapphire measures 5.84 x 5.06 x 3.50 mm, and it is cut in a mixed brilliant pavilion and step crown configuration to combine scintillation with classical cushion character. The stone displays a medium light blue color intensity that is immediately appealing for those who favor a lively, delicate blue rather than a deep, inky tone. Clarity is graded slightly included as seen at eye level, which means minor natural characteristics are present but do not substantially detract from the gems transparency or overall visual appeal. Polish has been assessed as excellent, and the stone is offered without enhancement. Origin is Ceylon, Sri Lanka, a classic and much sought after locality for fine blue sapphires, and at The Natural Sapphire Company we disclose origin, clarity, enhancement status, cut and measurements to ensure a fully informed purchase.

From a gemological grading perspective this sapphire brings together several important strengths. The weight of 0.94 carat is significant for an untreated example, and the cushion shape with a mixed brilliant cut has been executed to yield good light return across the table and crown facets. The 3.50 mm depth relative to the average diameter of approximately 5.45 mm produces a depth that is about 64 percent, a proportion that tends to favor presence and color saturation without sacrificing too much brightness in a medium light tone. Slightly included clarity at eye level indicates that the inclusions are visible when examined directly without magnification, but in practical use they are subtle and can add to the gem's natural character without weakening the corundum matrix. Excellent polish contributes to crisp facet junctions and a clean surface that maximizes the stone's brilliance and makes the medium light color read consistently in varied lighting.

Hardness and durability are fundamental when evaluating a sapphire for daily wear, and corundum ranks nine on the Mohs scale of mineral hardness, second only to diamond at ten. Compared to other common jewelry gems such as quartz on seven, topaz on eight, and spinel which is also robust but can exhibit different optical properties, sapphire is exceptionally resistant to scratching and abrasion. That high hardness ensures excellent longevity for rings and pieces that will be worn frequently, and when set properly the stone will withstand the rigors of everyday life better than most colored gemstones. For safety and conservation we recommend conventional setting choices, such as four or six prongs with well protected corners, or a bezel for particularly active wearers, and a modest elevation from the mounting to reduce the risk of impact on the girdle. Cleaning with warm soapy water and a soft brush is recommended, ultrasonic cleaning is generally safe for untreated corundum but should be used with caution if inclusions have fluid features, and exposure to harsh chemicals or sharp temperature changes should be avoided.

The combination of factors that make this sapphire desirable are its near one carat weight, its Ceylon origin, its lack of enhancement, and the balanced medium light blue tone with excellent polish and a pleasing cushion outline. Untreated sapphires from Sri Lanka retain a premium in the market because heat treatment is a common and accepted enhancement in the trade, and finding a transparent, no enhancement example with good eye cleanliness and a lively cut is comparatively rare. For an educated buyer this gem offers both aesthetic satisfaction and long term value, as its physical properties and disclosed provenance allow for confident appraisal and setting choices. At The Natural Sapphire Company we provide full disclosure and can assist with independent certification, bespoke mounting recommendations, and design consultations to ensure the stone is matched to a setting that complements its cut and color while protecting its structure. This sapphire is versatile enough for classic solitaire rings, elegant three stone designs, and refined pendants, and because of the stone durability and polish it will perform beautifully as a daily wear centerpiece with proper setting and care.
