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

One transparent 1.17 carat emerald cut bi color parti sapphire is presented with dimensions of 6.90 x 5.58 x 3.04 mm, faceted in an emerald cut that emphasizes linear facets and a broad table, clarity graded as very slightly included at eye level, faint color intensity, and an excellent polish, enhancement heat treated, origin Ceylon Sri Lanka, offered by The Natural Sapphire Company. The stone displays a restrained, elegant presence due to its step cut geometry, which produces broad, mirror like flashes of light across the pavilion and table rather than the intense pinpoint scintillation associated with brilliant cuts, the parti color distribution renders subtle areas of pale yellow against near colorless zones, and the overall transparency and controlled facet junctions allow for clean light transmission and predictable visual performance when set in jewelry.

When compared to more commonly encountered gemstones, this Ceylon sapphire offers a distinct optical character, diamonds, with a higher refractive index and strong dispersion, typically exhibit greater fire and overall brilliance, while brilliant cut sapphires and other highly refractive gemstones present more scintillation, the emerald cut used here intentionally moderates those effects, favoring clarity and color contrast over maximum sparkle. Relative to gemstones such as topaz and aquamarine, which often have comparable transparency but lower refractive indices, this sapphire affords crisper facet reflections and a slightly higher light return, and compared to many commercial sapphires of uniform hue, the bi color nature of this stone provides a unique visual complexity that shifts with viewing angle and mounting, the heat treatment applied is a standard, stable enhancement that improves color uniformity while maintaining the natural character and origin, and the Ceylon provenance aligns with a history of producing sapphires with lighter tones and good clarity. For design considerations, the emerald cut and very slightly included clarity make this piece well suited to settings that highlight the table and step facets, where the parti color can be framed and appreciated, and The Natural Sapphire Company provides full details to assist in selecting an appropriate mount to optimize the stone response in finished jewelry.
