1.08 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This round blue sapphire weighs 1.08 carats, and measures 6.33 by 6.31 by 3.34 millimeters, a size and proportion that sit comfortably in the classic range for a center stone with presence and wearability. The cutting style is faceted, executed in a mixed brilliant cut that combines the best attributes of brilliant and step faceting, and the overall polish has been graded excellent. Clarity is described as eye clean, which means that under normal viewing conditions the stone shows no inclusions visible to the unaided eye, a highly desirable attribute that preserves the gem s visual purity and allows the cut to perform without distraction. The color intensity is medium, producing a lively Ceylon blue that balances saturation and brightness, and the origin is Ceylon Sri Lanka, a source long appreciated for sapphires with a clean, vibrant hue. The stone has undergone disclosure heat treatment, a stable and commonly accepted enhancement for sapphires that improves color and clarity while maintaining the integrity of the natural crystal. At The Natural Sapphire Company we present this sapphire with full disclosure, and with the cut, clarity, and origin all identified so that educated buyers can evaluate its intrinsic and aesthetic merits accurately.

The geometry of the faceting is central to this sapphire s visual appeal, and the mixed brilliant design has been chosen to maximize light play while preserving color. Mixed brilliant cuts typically pair a brilliant style crown with a modified pavilion or step facets below the girdle, and that combination allows the crown s small facets to break light into scintillation while the pavilion s planes control return and depth of color. With an average diameter of approximately 6.32 millimeters and a depth of 3.34 millimeters, this sapphire exhibits a depth percentage of about 53 percent, a proportion that supports strong return of light without overly deep color extinguishing the stone s brilliance. The facet junctions are precisely aligned, and the symmetry contributes to even light dispersion across the table and around the crown, giving the gem a lively play of light when it is tilted, and a crisp central window when viewed face up. The mixed brilliant geometry is particularly effective for Ceylon sapphires of medium color intensity, because it amplifies the stone s inherent brightness and allows internal reflections to dance rather than sink, producing a combination of brilliance and color that is attractive both in daylight and under incandescent lighting.

Clarity and color work together in this sapphire to create a balance prized by connoisseurs. The eye clean clarity grade means that the gem presents a clean visual field to the viewer, so that light is free to travel through the crystal without significant interruption from inclusions. This clarity enhances apparent transparency and contributes to the perception of a larger, more luminous stone when set. The medium color intensity produces a vivid but not overpowering blue, a tone often associated with classic Ceylon sapphires, and it performs well in a variety of mounting styles and metal colors. Heat treatment, disclosed and stable, is a routine enhancement that improves color distribution and can reduce the visibility of minor inclusions, while leaving the stone s natural origin and crystal structure intact. Buyers who value traceable provenance will appreciate that this sapphire is identified as originating from Ceylon Sri Lanka, a region with a long history of producing sapphires that combine appealing hue and clarity, and that provenance often adds a qualitative layer to the stone s desirability among collectors and gem enthusiasts.

For an educated buyer evaluating this sapphire, several practical considerations underscore its value. First, the combination of a clean eye level clarity and an excellent polish means the stone will display maximum brilliance in jewelry without concern for visible internal distractions, a key factor when assessing daily wear pieces such as engagement rings or a prominent pendant. Second, the mixed brilliant faceting geometry provides both scintillation and controlled color saturation, making the gem versatile across different lighting environments and mounting designs. Third, the one point zero eight carat weight places the sapphire in a category that is immediately wearable and also collectible, particularly when paired with verified origin and transparent treatment disclosure. At The Natural Sapphire Company we emphasize responsible disclosure and expert cutting, and we can provide additional documentation and images on request to support a careful purchase decision. For mounting, settings that allow light to enter the pavilion while protecting the girdle are recommended, and prong settings or open gallery bezels are excellent choices to showcase the stone s geometry and light performance. With its combination of Ceylon origin, mixed brilliant faceting, eye clean clarity, and excellent polish, this sapphire represents a thoughtfully balanced choice for buyers seeking both beauty and a clear, factual basis for valuation.
