5.90 Ct. Bi Color Ametrine from Brazil

This beautiful transparent 5.90 carat emerald cut bi color ametrine from Brazil is a standout offering from The Natural Gemstone Company, with precise dimensions of 12.42 x 9.63 x 6.65 mm, a faceted emerald cut, and an eye clean clarity grade as evaluated at eye level. The vivid color intensity and excellent polish make the distinct golden and purple zoning pop with clean separation and lively brilliance, a level of color contrast that many ametrines on the market lack. Where mass market ametrines are often pale or unevenly cut, this gem has been expertly faceted to maximize light return and color split, which creates a balanced, wearable aesthetic ideal for a statement ring or bespoke pendant. The stone has been heat treated, a widely accepted enhancement that stabilizes and enriches color without compromising structural integrity, and its transparent nature and refined cutting mean it outshines many treated pieces that still appear cloudy or poorly proportioned.

When evaluating durability and everyday practicality, compare this ametrine to other popular gems including fire opal, listed opal type Fire Opal in our broader catalog. Ametrine is a variety of quartz with Mohs hardness 7, offering substantially greater scratch resistance and toughness than typical fire opal specimens, which generally rate about 5.5 to 6.5 on the Mohs scale. That difference matters for jewelry that will be worn frequently, as the higher hardness of this ametrine reduces the risk of surface wear and chips compared to softer opals and some other collectors stones. Compared to citrine and amethyst, which share the same quartz family hardness, this bi color ametrine provides the unique visual appeal of two colors in one crystal, increasing both rarity and perceived value versus single tone stones. In short, this gem combines the durability needed for daily wear, the rarity and visual drama of bi color zoning, and the craftsmanship of a precise emerald cut, making it a superior choice for customers seeking a polished, wearable, and investment worthy stone from The Natural Gemstone Company.
