3.02 Ct. Blue Cabochon Sapphire from Ceylon (Sri Lanka)

When you are searching for the perfect gemstone to anchor a bespoke piece, you want clarity about what will make that design sing, and you want confidence that the stone will perform beautifully in real life, not just on paper. This opaque 3.02 carat oval blue sapphire answers both needs. Its generous weight and classic oval dimensions of 9.14 by 7.20 by 4.83 millimeters give you a presence that reads as substantial without overpowering most settings, making it ideal whether you are planning an engagement ring with personality, a refined pendant that hangs with quiet authority, or a signature ring for everyday wear. The double cabochon cut and excellent polish mean the surface is smooth, tactile, and radiantly lustrous, offering a look and feel that invites touch and admiration. If your priority is a stone that harmonizes size, shape, and finish for custom work, this sapphire is a natural conclusion to the search.

Designers and clients who choose cabochons do so because the cut communicates warmth, depth, and a timeless aesthetic that faceted stones do not replicate. The double cabochon form of this sapphire produces a softly domed top and a rounded back, amplifying the deep, dark color intensity while producing a focused, velvety field of blue. That saturated blue is intrinsic to the gem and enhanced by expert heat treatment, a standard and stable enhancement that brings out the color without compromising structural integrity. At an eye-level clarity grade of very slightly included, the stone shows natural character without visible distractions, which is particularly desirable for custom pieces where the gem is the central voice. The substantial thickness of 4.83 millimeters allows jewelers to sculpt secure bezels, collet settings, or integrated mounts that cradle the cabochon, and the modestly broad oval silhouette translates beautifully into both horizontal and vertical orientations in bespoke designs.

Practical considerations matter when you commission an heirloom, and this sapphire checks those boxes as well. Corundum’s well-known durability is an asset for pieces intended for daily wear, and the cabochon profile further reduces exposure to chipping by minimizing sharp edges. The 9.14 by 7.20 millimeter footprint fits elegantly into a wide range of custom templates, from delicate, low-profile rings that sit close to the finger to bolder cocktail rings or bespoke cufflinks and brooches that celebrate the stone’s depth. Set in a full bezel, this gem will be protected and secure, and set in a custom open-back mount it can interact with light to reveal subtle nuances in tone and saturation. The excellent polish guarantees a smooth, mirror-like finish that enhances comfort against skin and allows the stone’s deep blue to present evenly across its surface.
