8.14 Ct. Bi Color Ametrine from Brazil

One beautiful transparent 8.14 carat oval shape bi color ametrine from Brazil that measures 15.26 x 12.30 x 6.83 mm, faceted with a mixed brilliant cut, offers an immediate presence that most ametrines on the market cannot match. Many commercially available ametrines are offered in smaller sizes, often under 3 carats, making a clean and intensely colored stone of this scale a notable find. This gem is evaluated as eye clean at eye level, shows intense color intensity, and enjoys an excellent polish, and it has no enhancement. The combination of natural bi color zoning, clear transparency, and a superb mixed brilliant faceting delivers vivid color separation and strong light return, qualities that are amplified by the generous 8.14 carat weight. At The Natural Gemstone Company we place this gem in a special category, because weight, color, clarity, cut, and origin combine to produce a stone that reads as both rare and immediately wearable.

Weight is the single most influential factor when assessing the rarity and market value of colored gemstones, and an 8.14 carat ametrine occupies a different tier from smaller stones. Value per carat for gemstones typically increases in a non linear fashion as size grows, because larger crystals with even color distribution and minimal inclusions are far less common in nature. In the case of ametrine, which requires the simultaneous formation of amethyst and citrine zones within the same crystal, large clean specimens with intense color contrast are particularly scarce. The 15.26 by 12.30 millimeter face up dimensions provide a broad table that showcases the bi color effect vividly, while the 6.83 millimeter depth supports excellent light performance without appearing deep or dark in the setting. A mixed brilliant cut was chosen to maximize scintillation and to balance fire with the bi color transition, so the extra weight translates into more brilliant facets and more dynamic light play, rather than just bulk.

Compared with typical market offerings, this ametrine stands out for several reasons. Many commercial ametrines are heat treated or otherwise enhanced to deepen color, and many are cut to conserve weight at the expense of ideal proportions or polish. This gem is natural and untreated, offering collectors and designers a purer material to work with, and its Brazilian origin places it among the most sought after sources for quality ametrine. The eye clean clarity at this size is another differentiator, because inclusions that are acceptable in small stones become obtrusive in larger sizes. Excellent polish and precise faceting ensure that the light performance is optimized, which matters more with larger table sizes because any cutting or polishing flaws become more visible. From a value perspective, purchasing an untreated, well cut, eye clean 8.14 carat ametrine represents superior long term value compared to acquiring multiple smaller stones or treated material, because the market rewards size and natural provenance, especially when paired with intense color and professional finishing.

For designers, collectors, and connoisseurs seeking a signature piece, this 8.14 carat oval bi color ametrine is an ideal candidate for a high impact ring, a statement pendant, or a bespoke heirloom piece, because its proportions allow for a balanced bezel or claw setting that protects the stone while showcasing its bi color charm. The substantial face up area photographs beautifully and proportionally on the finger as shown in our styling photos, and the durable nature of this gemstone makes it suitable for everyday wear with basic care. At The Natural Gemstone Company we can advise on settings that protect the pavilion and maximize the color transition, and we provide clear documentation of origin and treatment status to support both aesthetic and investment decisions. If you seek a rare ametrine that combines exceptional weight, proven quality, and natural beauty, this stone is a market leading option, and our team is ready to assist with additional images, measurements, or setting recommendations to ensure this 8.14 carat treasure becomes the centerpiece you envision.
