3.54 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One transparent 3.54 carat oval blue sapphire, dimensions 9.43 x 7.39 x 5.65 mm, mixed brilliant cut, clarity graded very slightly included when evaluated at eye level, vivid color intensity, and excellent polish. Origin Ceylon Sri Lanka, no enhancement. The mixed brilliant cut maximizes light return while preserving weight, and the excellent polish enhances surface luster and color saturation. The clarity is very slightly included at eye level, which means small natural inclusions are present but do not distract from overall transparency or performance, and these internal features are characteristic of natural Ceylon material. The measured proportions yield an attractive table and pavilion balance, and the oval shape sits comfortably in a wide range of settings from solitaire rings to pendants and custom designs. The Natural Sapphire Company provides this detail to allow precise evaluation for design and setting decisions.

From a durability perspective this sapphire is exceptionally well suited to daily wear, corundum rates 9 on the Mohs scale, second only to diamond, which gives it excellent resistance to scratching from everyday materials. Corundum has no true cleavage, which reduces the risk of splitting along planes, and sapphires generally show good toughness, meaning they withstand routine knocks and handling better than many gemstones. This specific stone is unheated and unenhanced, which preserves its natural stability, and it is also chemically stable and resistant to the mild acids and household chemicals encountered in daily life. As with any natural gem, care should be taken to avoid severe impacts and sudden thermal shock, particularly where internal inclusions are present, and protective mounting styles such as bezel settings or well positioned prongs will further minimize risk to pavilion and girdle areas. Routine cleaning with warm soapy water and a soft brush is appropriate, ultrasonic cleaning is usually acceptable for clean, inclusion free sapphires but should be confirmed for any stone with significant inclusions, and professional inspection by a jeweler is recommended if the sapphire will be exposed to heavy or continuous wear. These durability attributes, combined with the gemological quality and provenance, make this 3.54 carat Ceylon blue sapphire a practical and enduring choice for everyday jewelry, as represented by The Natural Sapphire Company.
