0.73 Ct. Bi Color / Parti Sapphire from Madagascar

This exquisite transparent 0.73 carat oval bi color or parti sapphire measures 5.56 by 4.53 by 3.44 millimeters, and presents a vivid and complex palette that will stand out in any jewelry setting. The mixed brilliant faceted cut maximizes light return while preserving the unique zonal colors that make parti sapphires so desirable. With intense color intensity and an excellent polish, each facet plays a role in emphasizing the stone s internal contrasts, so that green blue flashes sit alongside subtle golden yellow areas depending on the angle of view and the lighting conditions. Set as a solitaire in a simple bezel or prong mount, or as the focal point in a halo or three stone design, this sapphire will command visual attention, offering a dynamic presence that reads as both contemporary and timeless.

From a grading perspective this sapphire is described as very slightly included when evaluated at eye level, a clarity grade that balances natural character with practical beauty. The inclusions are modest and do not detract from brilliance or durability, they are typical of natural material and can serve as a fingerprint confirming natural origin for the connoisseur. The excellent polish and well executed mixed brilliant cut further enhance apparent clarity by promoting strong light performance and minimizing windowing. For buyers who consider proportion, weight and face up appearance, the 0.73 carat weight combined with the compact oval dimensions delivers a lively visual spread that reads larger on the finger than weight alone might suggest.

This sapphire has been heat treated, a widely accepted and stable enhancement in the trade that improves color uniformity and removes unattractive brownish tones without altering the fundamental identity of the stone. Heat treatment is a standard practice for many of the fine sapphires on the market, and when disclosed it allows educated buyers to evaluate value based on natural origin, hue complexity, and optical quality, rather than on treatment status alone. The gem originates from Madagascar, a source noted for producing parti and bi color sapphires with complex zoning and attractive saturation. Madagascar sapphires offer an appealing combination of character and rarity, and for the buyer seeking provenance this origin adds measurable interest relative to fully commercial material.

At The Natural Sapphire Company we present this gem with full disclosure and practical information so that informed buyers can make a confident decision. The sapphire s durability, with corundum hardness of nine on the Mohs scale, makes it suitable for everyday wear in rings, pendants, and other jewelry, while the intense coloration ensures it will remain a memorable focal point. For collectors who appreciate natural variation and for designers who want a stone that changes its personality with movement, this 0.73 carat oval parti sapphire represents a rare opportunity. Consider how the stone will interact with metal choice and side stones, as a warm gold setting will enhance the yellow areas, while a white metal will dramatize the blue green tones, offering multiple stylistic directions for a single exceptional gem.
