1.80 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional transparent 1.80 carat oval blue sapphire measures 7.99 x 6.09 x 4.42 millimeters, and it presents a classic length to width ratio of 1.31, producing a balanced and elegant oval outline. The cutting style is faceted with a mixed brilliant design, combining a brilliant facet arrangement on the crown with a controlled step influenced pavilion, the combination engineered to maximize return of blue saturation and lively facet scintillation. With a depth of 4.42 millimeters the depth percent is 62.8 percent relative to the average diameter, a proportion that preserves weight while maintaining efficient light performance through the table and pavilion. Clarity is graded very very slightly included at eye level, VVS, which in practical terms means the stone is effectively eye clean, exhibiting exceptional transparency and minimal internal distraction to the path of light. Color intensity is intense, showing concentrated blue saturation typical of fine Ceylon sapphires, and the excellent polish and symmetry of the facet junctions ensures crisp facet contrast and stable, lively scintillation. This sapphire is heat treated, a stable and widely accepted enhancement that refines and stabilizes color without compromising structural integrity, and its origin is Ceylon Sri Lanka, a source renowned for vivid, well saturated blue material.

Durability for daily wear is a defining characteristic of corundum, and this sapphire benefits directly from that material integrity. On the Mohs scale sapphire ranks nine out of ten, providing outstanding resistance to scratching and abrasion, and corundum lacks true cleavage, which contributes to reliable toughness in everyday jewelry applications. The mixed brilliant cut and excellent polish further reduce microabrasion by providing smooth facet planes, and the compact oval proportions allow secure mounting options, including four or six prong settings or a protective bezel, which enhance resistance to knocks and edge contact. Heat treatment is stable under normal wear conditions, and standard care recommendations apply, including routine cleaning with warm soapy water and a soft brush, avoidance of prolonged exposure to strong acids or harsh chemicals, and protection from severe thermal shock or heavy impact. The Natural Sapphire Company evaluates each stone for cut and finish to ensure it integrates well into daily wear rings, pendants, or bracelets, and our technical assessment confirms this 1.80 carat Ceylon sapphire as a durable, technically refined choice for everyday fine jewelry.
