0.93 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire is a transparent 0.93 carat oval, with precise dimensions of 6.00 by 4.99 by 3.90 millimeters, presented in a mixed brilliant cut and finished with an excellent polish. The mixed brilliant cut combines a brilliant style crown with a faceted pavilion to optimize return of light, creating a lively balance of scintillation and overall brightness that is well suited to the oval silhouette. The clarity is described as very very slightly included, evaluated at eye level, which in practical terms means that the stone presents as eye clean under normal viewing conditions and retains a fine degree of internal purity. The color is of faint intensity, manifesting as a delicate pale blue that reads as refined and understated rather than saturated, and the gem has been heat treated, a stable and widely accepted enhancement used to refine tone and clarity. These specifications together define a gem that is refined, wearable, and reliable for a range of jewelry applications.

The proportions of this oval are particularly relevant to its visual performance. With a length to width profile that approximates a classic oval ratio, and a measured depth of 3.90 millimeters, the stone sits with a pleasing presence that balances surface spread and depth. The mixed brilliant faceting pattern is arranged to produce both flashes of white light and subtle spectral dispersion, which complements the faint blue hue by emphasizing brightness without overwhelming the delicate tone. The excellent polish further enhances these optical effects, providing crisp facet junctions and smooth surfaces that increase contrast and clarity of reflection. At 0.93 carat, the gem occupies a practical size class that reads as substantial in solitaire settings while remaining versatile as a center or accent stone in more complex designs.

The origin of this sapphire is Ceylon, now known as Sri Lanka, and that provenance contributes materially to its intrinsic and perceived value. Sri Lankan sapphires carry a long established reputation for producing stones with finely distributed color and lively brilliance, often favoring lighter to medium tones that are prized for their elegance and versatility. Geologically, Ceylon deposits have produced high quality corundum due to unique combinations of metamorphic host rocks and fluid chemistries, and stones from these sources are recognized in trade and by connoisseurs for their particular combination of clarity and brightness. Provenance from Ceylon is therefore not merely a geographic label, it is an indicator of a specific gem character and historical desirability. For buyers who place importance on traceability and traditional gemstone pedigrees, the Ceylon origin adds a measurable premium relative to similar stones from undetermined sources.

Treatment and practical considerations are addressed plainly and transparently. The sapphire has been heat treated, a standard and accepted process in modern gemology that stabilizes and refines color and clarifies small inclusions, without compromising the structural integrity of the stone. Heat treatment is broadly accepted in the market and does not carry the same value reduction as more invasive or synthetic interventions. When considering settings, the stone’s faint blue tone and eye clean appearance render it suitable for a wide variety of metals and design languages, from minimalist platinum or white gold solitaires that emphasize cool tones, to yellow or rose gold mountings that can create a warm contrast and emphasize the gem’s delicate hue. The Natural Sapphire Company provides full disclosure on origin and treatment, and this example embodies the firm’s focus on quality, traceable provenance, and gemological accuracy, making it a considered choice for clients seeking a classic, well documented Ceylon sapphire.
