3.07 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent blue sapphire presents at 3.07 carat, a weight that places it in a distinct category for natural, untreated Ceylon stones, and one that materially contributes to its rarity and value. The gem is cut to a cushion shape with a mixed brilliant facet arrangement, and measures 8.26 x 7.02 x 5.30 mm, dimensions that provide a balanced face up profile and strong light return. Clarity is graded slightly included, evaluated at eye level, a typical and acceptable characteristic for natural sapphires that does not detract from the gem's overall appearance or durability. Color intensity is medium, offering a pleasing, even blue that is characteristic of quality Sri Lankan material, and the polish is excellent, enhancing the stone's luster and facet definition. There has been no enhancement, and the origin is Ceylon, Sri Lanka, a provenance known for producing well saturated, collectible blue sapphires.

Weight plays a central role in both the market valuation and the practical desirability of this sapphire, and the 3.07 carat size carries significance beyond simple millimeter measurements. In corundum, value scales non linearly with carat weight, larger natural untreated stones becoming incrementally rarer as size increases, and the 3 carat threshold is often a notable price and rarity marker, particularly for material with clean presentation and excellent polish. For jewelry applications, the 8.26 x 7.02 mm face up dimensions combined with the 5.30 mm depth produce a visually substantial presence on a finger or in a pendant, while retaining proportions that allow skilled setters to secure the stone without excessive bezel work. From a collecting perspective, an untreated Ceylon sapphire at this weight is of interest because it represents a convergence of desirable factors, namely natural origin, lack of enhancement, resolute color characteristics, and a weight that sits above many common sizes. The Natural Sapphire Company provides this detailed grading information to assist in objective assessment, and to clarify how the 3.07 carat weight contributes to the gem's scarcity, valuation, and suitability for fine jewelry.
