1.14 Ct. Bi Color Andalusite from Madagascar

This is a beautiful, transparent 1.14 carat oval bi color andalusite from Madagascar, presented by The Natural Gemstone Company. The oval measures 7.80 x 6.11 x 3.58 mm and is cut in a mixed brilliant style to balance table brilliance with well proportioned pavilion facets. At eye level the stone is graded very very slightly included, indicating minimal visible inclusions that do not detract from face up appearance, and the polish is excellent. The color intensity is intense, and the bi color nature of this andalusite displays strong pleochroism, shifting between warm brown and olive green tones as the stone is viewed from different angles. There has been no enhancement to this gem, which preserves the natural zoning and optical character collectors and connoisseurs prize, and Madagascar provenance further enhances its desirability due to the region known for producing fine, naturally colored andalusite specimens. For an educated buyer, the combination of intense natural color, high polish, and a mixed brilliant cut that optimizes both color and light return makes this piece a rare and versatile choice for quality jewelry.

For customization, this oval bi color andalusite adapts exceptionally well to a wide variety of settings and design concepts. In a ring, a four or six prong setting will secure the stone while allowing light to enter from the sides to emphasize pleochroism, and a low bezel can be used for a more protective, everyday wear option given andalusite hardness of approximately 6.5 to 7.5 on the Mohs scale. For a statement pendant, orienting the oval vertically or east west will create different color presentations, and an open gallery or halo of small brilliant melee diamonds will increase perceived size and add contrast without obscuring the bi color effect. For earrings, selecting matching stones or complementary accent colors such as tsavorite green or cognac diamonds will bring out the olive and brown facets respectively. The mixed brilliant cut also lends itself to three stone designs and split shank settings, where side stones can be chosen to complement specific faces of the pleochroic color. For bespoke commissions and technical guidance on prong counts, bezel depth, and metal choices including yellow gold to warm the brown tones, rose gold for a softer palette, or platinum for a modern white metal look, contact The Natural Gemstone Company and our design team will provide personalized recommendations and CAD visuals to ensure the final piece showcases this natural, untreated andalusite to its fullest potential.
