3.93 Ct. Bi Color / Parti Sapphire from Ceylon (Sri Lanka)

This transparent 3.93 carat emerald cut bi color sapphire from Ceylon, Sri Lanka, is a compelling example of parti coloration, presenting a vivid division between a yellow green field and a deep blue pavilion, with dimensions of 11.38 by 6.28 by 4.54 mm. The gem is faceted in an emerald cut, which emphasizes its step facets and long, elegant profile, making the color zoning both dramatic and wearable. Clarity has been graded as included at eye level, which is typical for natural sapphires and gives the stone character without compromising its visual appeal when well set. The color intensity is listed as intense, and the polish is excellent, producing strong light return across the table and facets. This sapphire has been heat treated, a widely accepted and stable enhancement that improves tone and transparency in Ceylon sapphires, and should be considered a standard practice for stones of this origin. The combination of substantial carat weight, refined cutting, and vivid parti coloration makes this stone desirable to the educated buyer seeking a unique centerpiece with natural origin and documented treatment history, available through The Natural Sapphire Company.

When planning a setting, this sapphire adapts beautifully to a wide variety of designs, from classic solitaires and halo engagement rings to bespoke three stone layouts, pendants, studs, and statement rings for men. The emerald cut and strong color split invite creative orientation, for example setting the gem east west to showcase the split horizontally across a finger, or bezel mounting to protect the corners while allowing the color contrast to read clearly. A low prong or open back setting will maximize light through the pavilion to enhance transparency and the intense color, while a thin millegrain bezel or knife edge shank will keep the profile modern and wearable. Metal choice changes the perceived temperature of the colors, yellow gold amplifies the warm yellow green, rose gold softens the contrast, and platinum or white gold provides a cooler frame for the blue, making it ideal for diamond halos or pavé shoulders to add sparkle without competing with the parti effect. For custom commissions, consider companion stones such as small green tsavorites, cognac diamonds, or vivid blue sapphires to accentuate one or the other color zone.
