6.17 Ct. Bi Color / Parti Sapphire from Madagascar

I am pleased to introduce a truly special gemstone from The Natural Sapphire Company, a transparent, GIA certified Green Blue sapphire weighing 6.17 carats. This oval shape, bi color, or parti sapphire measures 12.60 by 9.78 by 6.14 millimeters, and it has been expertly faceted in a mixed brilliant cut to maximize both brilliance and color play. The Lab Color Classification is Green Blue, and the stone displays an intense color intensity that shifts gracefully between green and blue depending on the angle and lighting. Clarity is graded as slightly included when evaluated at eye level, and the polish is excellent, which helps the sapphire present a lively, clean surface. Importantly for collectors and connoisseurs, this sapphire is natural and unenhanced, and its origin is Madagascar, a source known for producing beautiful, characterful sapphires. The GIA certification provides independent confirmation of these details, offering confidence in the gem quality, identity, and origin.

Visually, this sapphire offers a refined and captivating presence that will work beautifully in a variety of bespoke jewelry designs. The mixed brilliant faceting encourages lively return of light, while the parti color character creates pockets of cooler blue and warmer green that change as the stone is turned. This dynamic color makes the gem particularly versatile alongside different metal choices, including warm yellow gold to emphasize the green tones, classic white gold or platinum to accentuate the blue aspects, or rose gold for a more contemporary contrast. The oval outline provides elegant finger coverage and a flattering silhouette, and at 6.17 carats the gem will read as substantial but wearable. The slightly included clarity grade means that inclusions are present but not distracting to the naked eye, and these natural features can be celebrated as part of the stone story, evidence of authentic natural formation. Because the sapphire is not heat treated or otherwise enhanced, it carries greater rarity and long term value for collectors who prefer untreated gemstones.

At The Natural Sapphire Company we can assist you in imagining and realizing the perfect setting to showcase this Madagascar Green Blue sapphire, whether you prefer a classic solitaire to emphasize color purity, a halo to amplify perceived size and sparkle, a three stone design to tell a meaningful story, or a custom creation that reflects personal style. We also offer detailed imagery and video on request to show how the parti color behaves in different lighting conditions and to highlight the fine mixed brilliant faceting and excellent polish. Our gem specialists can provide guidance on metal choice, mounting style, and secure setting techniques that protect the stone while maximizing visual impact.
