1.12 Ct. Bi Color Sapphire from Madagascar

One beautiful transparent 1.12 carat emerald cut shape bi color sapphire, measuring 6.16 x 4.72 x 3.90 mm, presents a compelling combination of color and clarity that will appeal to the educated gemstone buyer. The stone is an emerald cut, a step cut that creates broad, elegant facets and a refined, hall of mirrors effect, and its clarity grade is very very slightly included as evaluated at eye level, indicating that the stone reads clean to the unaided eye with only minor internal characteristics that do not interrupt light transmission or overall transparency. Color intensity is described as intense, and the gem displays a distinct bi color distribution that moves between deep teal and rich green depending on angle and lighting. The polish on this sapphire is excellent, providing crisp facet junctions and sharp reflections that maximize the stone's ability to return light. Importantly for collectors who insist on natural material, this sapphire has no enhancement, and its origin is Madagascar, a source known for producing a broad palette of high quality, naturally colored sapphires.

The emerald cut is central to the way this sapphire reflects and interacts with light, because step facets tend to emphasize color and clarity rather than the scintillation and dispersion seen in brilliant cuts. In practical terms, the large, parallel facets create broad flashes of color and internal reflection, giving the stone a deep, architectural glow that can appear as bands or planes of color when rotated. This creates a very different viewing experience when compared to, for example, round or cushion brilliant cut sapphires where numerous small facets produce rapid, lively scintillation and more obvious sparkle. The excellent polish enhances the emerald cut effect, allowing clean mirror like reflections from the facet planes and excellent light return for a step cut. The very very slightly included clarity means viewers will perceive a clean window into the sapphire, with inclusions being faint and not disruptive to the stone s transparency or its ability to display saturated color. For buyers prioritizing a pure, contemplative color display over flash, the emerald cut showcases the bi color character in a way that many brilliant styles cannot.

Bi color sapphires occupy a distinct niche within the sapphire family because they present two or more dominant colors in a single crystal, and this Madagascar example is a textbook illustration of that phenomenon. The interplay of green and teal in this gem is a function of trace element chemistry and growth zoning within the crystal, and the combination of intense saturation and transparency allows each hue to read distinctly under different lighting conditions. Compared to single tone blue or green sapphires, which present a uniform plane of color, a bi color sapphire offers dynamic visual interest and a living quality, shifting from cool teal to warmer green as the stone is moved. The reflective quality in this stone emphasizes broad flashes and deep color wells rather than the pinpoint fire associated with diamonds or the busy scintillation typical of brilliant cut sapphires. Against other natural sapphire categories such as parti sapphires or teal sapphires, this gem stands out because of its clarity and its lack of treatment, producing a crisper, cleaner display of the bi color effect. For collectors and connoisseurs who value natural color zoning combined with excellent optical performance, the reflective presentation of this emerald cut stone is both rare and compelling.

For buyers assessing value, several objective factors increase this sapphire s desirability. The carat weight of 1.12 is substantial for an emerald cut sapphire of these dimensions, and the precise measurements of 6.16 x 4.72 x 3.90 mm translate into ideal pavilion depth and table size for a step cut that is intended to emphasize color. The grading indicators of intense color intensity, excellent polish, and very very slightly included clarity at eye level support a premium valuation, and the absence of enhancement affirms that the color and clarity are wholly natural. Origin is an important attribute for educated buyers, and Madagascar has built a reputation for producing richly colored, unique sapphires with pronounced zoning and rare tones, making provenance a positive factor in both aesthetic appreciation and market value. From a wearability perspective sapphires rate nine on the Mohs scale, providing exceptional durability for everyday wear in rings and other jewelry, and the emerald cut is particularly well suited to settings that protect the corners and showcase the color, such as four prong or bezel styles that allow light to penetrate the table while safeguarding the stone. At The Natural Sapphire Company we can advise on setting options that best present the bi color display and preserve the stone s value, because choosing the right metal and setting orientation directly influences how the gem will present its color in daily wear.
