1.00 Ct. Bi Color Sapphire from Madagascar

This exceptional bi color sapphire from Madagascar is a meticulously selected, transparent 1.00 carat emerald cut, with precise dimensions of 6.08 x 5.01 x 3.86 mm. The stone displays a medium intense color, presenting a dynamic blend of green and blue tones with subtle yellow inflections that shift with the angle of view, a characteristic that gives bi color sapphires their distinct personality. The gem is untreated, no enhancement, which is a decisive factor for the informed buyer who values natural color and geological provenance, and it carries an excellent polish that enhances surface brilliance and light return. The emerald cut itself contributes to the gem s refined aesthetic, offering long parallel facets that emphasize clarity and color zoning rather than hiding them, and the cut proportions have been executed to balance depth and face up size for an elegant presence in any mounting. Sourced in Madagascar, this sapphire benefits from an origin known for producing an array of rare and interesting colors in corundum, and collectors and connoisseurs will appreciate the combination of natural origin and the stone s clean presentation.

Clarity is an important determinant of value and visual appeal, and this sapphire is graded as very slightly included evaluated at eye level, indicating that inclusions are minor and do not detract from the gem s overall transparency or scintillation when viewed without magnification. For practical purposes this means the stone reads clean to the naked eye, and under loupe and microscope small natural features are consistent with untreated corundum, confirming authenticity and natural growth. The excellent polish enhances facet definition, allowing the emerald cut s step facets to produce linear flashes of light and rich color contrast that highlight the bi color effect rather than diffuse it. From a gemological standpoint the combination of natural, unenhanced origin, medium intense color, and very slightly included clarity is particularly desirable, because it preserves the gem s natural character while offering the brightness and saturation collectors seek. The 1.00 carat weight and the given dimensions make this sapphire substantial enough to command attention in rings, pendants, and bespoke pieces, while the durability of corundum, rated 9 on the Mohs scale, ensures excellent wearability for every day and heirloom jewelry.

When set in jewelry this sapphire s vibrant color will stand out in any setting, and its emerald cut profile lends itself to a variety of design directions that accentuate its distinct bi color display. For a striking solitaire, a minimal four prong mounting with a low profile will showcase the stone s table and emphasize the directional color shift. For added brilliance and contrast, a halo of fine white diamonds will amplify the visual saturation of the blue and green areas, while a bezel in warm yellow gold will draw out the warmer yellow green notes, making the stone appear more luminous. Orientation in the setting can be used as a design tool, by positioning the stone to present the preferred color to the viewer or to create a diagonal play of color across the finger or pendant. For those seeking a contemporary look, an east west mounting or a double bezel arrangement will emphasize the emerald cut geometry and produce an architectural aesthetic. At The Natural Sapphire Company we recommend reviewing the stone in the intended metal under natural daylight if possible, because the bi color phenomenon interacts with the surrounding metal and design details to create the final impression. Our gem specialists are available to discuss mounting options, provide high resolution imagery, and assist with custom design concepts to ensure that this rare, untreated Madagascar sapphire is presented in a setting that maximizes its color, clarity, and long term value.
