1.80 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 1.80 carat asscher octagon shape blue sapphire measures 6.99 x 6.96 x 3.94 mm, weighing 1.80 carats. The cutting style is faceted, with an asscher cut that presents step facets and a square octagonal outline, producing a balanced interplay of light and depth. Clarity is graded eye clean at eye level, indicating no inclusions visible to the unaided eye, enhancing visual purity and optical performance. Color intensity is medium, offering a well saturated blue that reads as lively under a range of lighting conditions, while the polish is excellent, contributing to crisp facet junctions and a bright surface luster. The gemstone has been heat treated, a common and stable enhancement that refines color and clarity, and its origin is Ceylon Sri Lanka. The Natural Sapphire Company affirms full disclosure of treatment and origin.

Sapphire ranks nine on the Mohs scale of mineral hardness, second only to diamond among commonly used gem materials, which gives this stone exceptional resistance to scratches and surface wear and makes it well suited for daily wear in rings, bracelets and pendants. The material also exhibits good toughness, reducing the risk of cleavage or fracture under normal use, and the eye clean clarity reduces the likelihood of inclusion related weaknesses. The excellent polish and precise asscher faceting further contribute to durability by minimizing surface irregularities where wear could initiate. Heat treatment used to enhance color and clarity in this stone is stable under normal wearing conditions, and does not compromise structural integrity when properly set. For maximum longevity a secure setting such as a bezel or protective prong arrangement is recommended for rings and bracelets that may encounter knocks, while pendants and earrings may be set with less protective profiles. Routine maintenance includes periodic inspection of the mounting for loose stones, cleaning with warm soapy water and a soft brush, and avoiding exposure to strong acids, alkalis, or sudden thermal shock. When handled and set appropriately this Ceylon sapphire from The Natural Sapphire Company combines enduring physical properties with refined optical qualities for reliable daily wear.
