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

This matched pair from The Natural Sapphire Company comprises a 0.59 carat and a 0.49 carat round blue sapphire, with precise dimensions 5.10 x 5.17 x 2.84 millimeters, and 4.80 x 4.88 x 2.59 millimeters respectively, each cut in a mixed brilliant style. The mixed brilliant faceting combines a brilliant cut crown to maximize scintillation, with a modified pavilion that controls depth and face up color, producing lively flashes without excessive windowing. Clarity is graded slightly included at eye level, indicating fine internal features that do not significantly interrupt light return, and the polish is excellent, preserving facet crispness and contrast. Color is described as medium intensity, typical of Ceylon origin stones, showing a vivid but not saturated blue with pleasing brightness, and the pair is completely untreated, enhancement none, which ensures natural color behavior under different light sources. The stones exhibit transparent material quality and consistent mixed brilliant symmetry, making them suitable for fine settings where optical performance and provenance are important.

For customization to match existing jewelry, we recommend an approach that begins with exact seat and profile specifications, using the supplied measurements and pavilion depths to design bezel or prong seats that secure the girdle without obscuring the crown. Because the two stones differ slightly in diameter and depth, settings can be calibrated numerically to equalize apparent size, either by a slightly raised seat for the smaller stone, or by a narrow halo on the smaller side to balance face up appearance while retaining total carat weight. Metal choice has a measurable effect on perceived color, so we advise warm 18 karat yellow or rose gold to enrich blue with subtle warmth, or platinum and rhodium plated white gold to emphasize a crisper cornflower blue. Additional options include matching side stone calibrations, diamond halos to increase sparkle and perceived size, and custom orientation or east west mounts to create a deliberate paired asymmetry. Our bench will produce CAD renders and mock ups to confirm proportion, we can precisely seat the stones to account for pavilion depth and girdle thickness, and we will hand set and finish the mounting to maintain the excellent polish of the sapphires. Please consult with The Natural Sapphire Company design team to supply photographs or the existing piece for a technical match, and we will provide recommended profiles and fabrication tolerances to integrate these Ceylon sapphires seamlessly into your existing collection.
