1.07 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent blue sapphire weighs 1.07 carats and is fashioned into a classic oval shape, measuring 6.97 x 4.98 x 3.67 mm. The cutting style is faceted with a mixed brilliant cut, a refinement that combines step facets and brilliant facets to optimize both color face up and internal light return. Evaluated at eye level, the stone is eye clean, presenting no visible inclusions to the unaided eye. Color is described as intense in intensity, and the pavilion and crown have been brought to an excellent polish, resulting in crisp facet junctions and a lively surface appearance. The sapphire has been heat treated, a conventional and widely accepted enhancement in the trade, and it is documented as originating from Ceylon Sri Lanka. These objective specifications establish the baseline attributes that define this gemstone and provide a clear foundation for further appraisal and setting considerations.

The mixed brilliant cut used for this sapphire is selected to balance saturation and brightness, and it performs particularly well in an oval outline where length to width proportions influence the perceived size and movement of color. At 6.97 mm by 4.98 mm and with a depth of 3.67 mm, the proportions fall into a range that favors efficient light return while maintaining a pleasing table size and outline. The facet architecture yields scintillation and a controlled play of light, drawing attention to the stone without overwhelming the eye with excessive sparkle. Because the gem is eye clean, the clarity supports a uniform transmission of light through the body of the stone, allowing the intense color to read evenly across the table and along the girdle. The excellent polish contributes to sharp facet reflections and minimizes surface disruptions, which enhances both brilliance and wearability when set into a ring or pendant.

Origin from Ceylon Sri Lanka carries a distinct significance in the gem world, and it is a meaningful factor in both aesthetic perception and market valuation. Sri Lankan sapphires have a long documented history and a reputation for producing stones with lively, often bright blue tones that can range from cornflower to deep blue depending on deposit and formation conditions. The geology of Sri Lanka favors the inclusion of trace elements such as iron and titanium in proportions that interact during crystallization to yield vivid blue hues, and the ancient alluvial deposits have historically produced stones with favorable clarity and color distribution. Provenance from Ceylon therefore informs expectations about color character and potential stability, and it often enhances desirability among collectors and connoisseurs who prioritize regional typicity. In addition to color and clarity considerations, origin contributes to the narrative and traceability of the gem, and when combined with transparent treatment disclosure it supports informed purchasing decisions grounded in verifiable information.

Heat treatment is disclosed for this sapphire, and it is important to contextualize that disclosure within industry practice and within The Natural Sapphire Company commitment to clarity and responsible sourcing. Heating is a common and stable enhancement applied to sapphires to improve color saturation and diminish certain silk or inclusions, and when properly executed it does not undermine structural integrity or long term stability. The stone retains the natural crystalline structure and hardness that make sapphire suitable for everyday wear, and its eye clean clarity and excellent polish make it an appropriate candidate for a range of settings from subtle solitaire presentations to more elaborate styles that emphasize the oval silhouette. The provenance from Ceylon adds a layer of value through recognized regional characteristics and documented history, and The Natural Sapphire Company provides full disclosure of origin and treatment to support appraisal and insurance documentation. For a buyer seeking a balanced combination of measured proportions, intense Ceylon blue color, reliable enhancement disclosure, and high standards of finish, this 1.07 carat oval offers a coherent set of qualities that align with rigorous gemological expectations and long term enjoyment.
