1.08 Ct. Bi Color Sapphire from Ceylon (Sri Lanka)

This transparent 1.08 carat radiant shape bi color sapphire from Ceylon, Sri Lanka, presents a balanced, near square outline and crisp faceting, measuring 5.59 by 5.51 by 3.76 mm. The radiant cut has been executed to emphasize scintillation and internal light return, and the stone exhibits a medium color intensity with a subtle two tone distribution that shifts between cornflower blue and a cooler violet depending on light and viewing angle. Clarity is described as very very slightly included, evaluated at eye level, indicating that inclusions are minimal and do not interfere with overall transparency or brilliance. The polish is excellent, contributing to clean facet junctions and lively reflections. Enhancement is heat treated, a stable and widely accepted treatment that improves color saturation while preserving the natural character of the sapphire.

This gem adapts readily to a wide range of jewelry settings, and its proportions and optical properties make it particularly versatile for custom work from The Natural Sapphire Company. For rings, a four or six prong setting will showcase the radiant cut and allow the bi color character to read, while a bezel setting provides a more protective profile for daily wear and helps stabilize the lower girdle depth. A halo of small melee diamonds or sapphires can increase visual size and enhance perceived color, whereas a three stone composition with tapered baguettes or cushion side stones will present a refined, architectural silhouette. For earrings and pendants the stone works well as a solitary stud or as the focal point in a drop design, where an open back or low profile gallery will permit light to pass through and accentuate the color shift. Consideration of metal choice offers additional customization, white metals preserve the cooler aspect of the blue, while yellow or rose gold can introduce warmth and alter the contrast to emphasize violet notes. For contemporary designs, an east west orientation or a tension mount can highlight the gem’s geometric character, and for vintage inspired pieces a delicate milgrain bezel and closed gallery will lend period appropriate depth. Technical notes for setters include the relatively shallow pavilion height, which benefits from a setting that allows adequate light entry, and the stable nature of heat treatment, which does not require special care beyond standard precautions for fine jewelry.
