3.16 Ct. Blue Sapphire from Thailand

This transparent 3.16 carat oval blue sapphire, measuring 9.73 x 7.99 x 4.24 mm, is a finely proportioned gem that combines substantial weight with an elegant outline. The mixed brilliant cut has been executed to maximize optical performance in an oval form, producing lively scintillation while preserving the depth of color that collectors prize. Evaluated at eye level the stone is graded slightly included, a clarity grade that indicates small natural internal characteristics which do not materially impair transparency or brilliance. The color is described as intense, a tone and saturation that delivers a vivid, velvety blue across the table and pavilion, and the excellent polish produces crisp facet junctions and clean reflections. This sapphire has been heat treated, a widely accepted and stable enhancement when disclosed, carried out to optimize color and clarity while preserving the gem's natural integrity. Origin is Thailand, a source known for producing rich blue sapphires with attractive firmness of color and reliable cutting traditions.

For the educated buyer this sapphire represents a compelling addition to a high end collection, offering a rare combination of weight, color intensity, and finish. At 3.16 carats the gem is large enough to command presence in a bespoke engagement ring or an elegant pendant, yet its oval proportions make it an especially versatile candidate for refined jewellery design. Heat treatment from Thailand is industry standard and when paired with excellent polish and mixed brilliant cutting, it provides a balanced profile of beauty and durability. Slight inclusions mean the stone is unquestionably natural, and its transparency allows light to traverse and interact with the internal structure for depth and life rather than masking the hue. The Natural Sapphire Company stands behind this sapphire with full disclosure of origin and enhancement, and we can arrange independent gemological documentation upon request to support provenance and valuation. For collectors seeking a gemstone that blends aesthetic excellence with sound gemological credentials, this sapphire is an intelligent and rewarding choice, offering both visual sophistication and long term desirability.
