0.74 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 0.74 carat cushion shape blue sapphire is a refined example of natural corundum, and it is offered by The Natural Sapphire Company with full provenance and careful evaluation. This stone measures 5.11 by 4.19 by 3.96 millimeters, and is fashioned with a mixed brilliant cut that combines the scintillation of modern brilliant faceting with the traditional pavilion geometry of a cushion outline. The clarity has been graded as very very slightly included when evaluated at eye level, meaning the pavilion and crown exhibit only minute internal characteristics that do not detract from the visual purity to the unaided eye. The color has been evaluated as intense in both saturation and tone, a deep, lively blue that displays excellent uniformity across the table without zoning, and the polish is excellent, yielding crisp facet junctions and lively light return. Importantly, this sapphire has no enhancement, an untreated example from Ceylon Sri Lanka, a region long respected for producing some of the finest blue sapphires in the world.

What makes this particular sapphire notably rare is the combination of its size and its natural, intense color. Sapphires in the under one carat range commonly present lighter tones or require heat treatment to achieve the depth of blue seen here, because smaller rough material often struggles to show the same saturation as larger crystals once faceted. Finding a transparent 0.74 carat cushion that exhibits true intense color without any enhancement is uncommon, and within the market there are relatively few stones that pair eye level clarity, vivid natural color, and the optical performance delivered by a precise mixed brilliant cut. The cutter has balanced pavilion depth and crown architecture to maximize both color saturation and brilliance, allowing the stone to appear larger and more vivid than its carat weight might suggest. Compared to the broad supply of small, treated, or murkier sapphires, this example stands apart as a collector grade gem that will appeal to connoisseurs who prioritize natural origin, visual purity, and exceptional cutting precision.

For the educated buyer, this sapphire represents both aesthetic and intrinsic value. The origin of Ceylon Sri Lanka brings a well documented historical and gemological pedigree, with many of the finest blue sapphires traced to that island, where unique trace element combinations contribute to a distinctive, often velvety blue that sits between mellow cornflower and deeply saturated royal blue. The absence of enhancement substantially increases rarity and market desirability, and it typically commands a premium relative to comparable treated material. From a technical perspective, corundum’s hardness and toughness rate high on the Mohs scale, making this sapphire exceptionally suitable for everyday wear in engagement rings, pendants, or heirloom pieces, while the excellent polish ensures maximum light performance and surface durability. We suggest settings that allow light to penetrate the pavilion and show off the stone’s intense color, such as open prong or low bezel styles, and recommend routine care with mild detergent and a soft brush, avoiding harsh chemicals and high temperature shock.

The Natural Sapphire Company stands behind the gemological assessments provided and can supply laboratory documentation upon request, including origin verification and detailed notes on clarity and cutting. For collectors and buyers who understand the nuances that determine long term value, this 0.74 carat Ceylon sapphire is a rare opportunity to acquire an untreated, intensely colored, and eye clean cushion that combines beauty with investment grade credentials.
