1.21 Ct.Tw.Total Carat Weight Blue Sapphire Pair from Ceylon (Sri Lanka)

This pair of Ceylon blue sapphires from The Natural Sapphire Company presents a tightly controlled set of technical specifications created for precision matching, each stone weighing 0.60 carats and 0.61 carats respectively, round shape, mixed brilliant cut, dimensions 4.97 x 5.00 x 2.96 mm and 4.99 x 5.05 x 3.17 mm. The mixed brilliant interpretation combines a faceted brilliant crown with a modified pavilion geometry to balance scintillation and windowing, resulting in consistent light return across both stones. Calculated pavilion depth proportions are approximately 59.4 percent for the 2.96 mm depth on the slightly narrower diameter, and approximately 63.1 percent for the 3.17 mm depth on the slightly larger diameter, a variance that has been compensated through facet planning and crown height adjustments to preserve a uniform face up presence. Clarity is graded very very slightly included at eye level, indicating only minute needle or crystal inclusions that do not interrupt overall transparency, polish is excellent, color presents with intense intensity characteristic of fine Ceylon material, and enhancement is limited to controlled heat treatment to optimize hue and saturation.

Pairing these sapphires required meticulous attention to dimensional symmetry, facet alignment, and optical phase matching, factors that determine perceived color and brilliance when stones are set side by side. The near equal carat weights and diameter measurements minimize face up size discrepancy, while the cutter adjusted facet angles to harmonize pavilion angles so that internal reflection patterns correspond under typical lighting conditions. For precision settings such as matched stud earrings or a bypass ring, small differences in depth suggest slightly different seat depths or bezel heights may be required, a nuance our gem cutters and setters account for to ensure even crown height and identical visual mass. When evaluating pairs, professionals focus on matching color grade, extinction pattern, and windowing behavior as much as numeric equality, and these two sapphires have been selected and prequalified to meet those criteria. For clients seeking technical excellence in matched natural sapphires, this pair from The Natural Sapphire Company offers a rigorously matched combination of weight, cut proportions, clarity, and color, ready for exacting jewelry design and setting.
