4.64 Ct. Ametrine from Brazil

From deep within the layered heart of Brazil, where slow cooling pockets of silica and tiny traces of iron once held secrets for millions of years, this single crystal began its quiet transformation into a gem that tells a story of time and light, The Natural Gemstone Company is proud to present this transparent 4.64 carat radiant shape bi color ametrine, its dual personality revealed in a single harmonious crystal, measured with exacting care at 11.56 by 9.26 by 6.24 millimeters. In the mine the crystal grew under fluctuating conditions, regions of the same crystal becoming tinted with the warm honey gold of citrine on one side, and cooled into the violet of amethyst on the other, creating the natural zoning that gives ametrine its rare and unforgettable bi color appeal. When the rough reached our artisans it was selected for its clarity and color, a piece that would respond beautifully to a radiant cut, chosen to amplify the contrast and to spread both colors across the crown of the gem with lively faceted flashes. As with every gem we carefully vet at The Natural Gemstone Company, this ametrine is natural with no enhancement, every facet and every plane bearing witness to the combined handiwork of nature and the lapidary.

The cutting process was both a technical decision and an aesthetic conversation between cutter and stone, the radiant cut chosen to balance brilliance with a broad table that celebrates the bi color division, the facets arranged to dance light through the stone and reveal subtle shifts as the viewer moves. The excellent polish enhances this dialogue between light and color, giving the surface a mirror smoothness that lets you peer into the transparent depths, and the clarity grade of very very slightly included evaluated at eye level means the gem presents an almost unblemished field of color to the naked eye, with only minor internal characteristics detectable under magnification. These characteristics are natural signatures of formation, not treatments or fillings, and they serve as a fingerprint of authenticity, reassuring you that what you hold is a genuine, honest gemstone. The light color intensity gives the ametrine a gentle, wearable palette, not overpowering but luminous, able to pair with warm or cool metals and to sit comfortably against skin tones without overwhelming.

Beyond beauty, practicality matters for daily wear, and quartz family gems like this ametrine have a durability profile that makes them well suited to many kinds of jewelry, with a hardness of seven on the Mohs scale that resists scratches from everyday materials and holds a polish for years. For daily wear rings, pendants, and bracelets, the radiant shape and the dimensions of this stone make it a versatile center that can be set in protective mounts such as bezel or halo settings that reduce the risk of impacts to the girdle and corners, while still allowing light to enter and showcase the bi color phenomenon. Ametrine does not have the cleavage that makes some gems vulnerable to sudden breakage, yet like all gemstones it benefits from mindful care, so we recommend removing jewelry during strenuous activity, avoiding prolonged exposure to high heat or strong chemicals, and cleaning gently with warm soapy water and a soft brush. The combination of natural toughness, stable color without enhancement, and an excellent polish makes this 4.64 carat radiant ametrine a fine candidate for an everyday piece that will age gracefully, its story accumulating small moments of life rather than losing its integrity quickly.

Owning this ametrine is like carrying a piece of Brazilian geology that has been shaped and then refined by careful human attention, The Natural Gemstone Company stands behind the provenance and the craftsmanship, offering this gem as a conversation starter, an heirloom in the making, and a wearable work of nature. Imagine the gem set in a custom pendant that swings and catches light at social gatherings, revealing first the citrine warmth and then the amethyst twilight with a single tilt, or imagine it as a signature ring that announces a love of authenticity and subtle color play. Each time you put it on you will be connecting to the long arc of its formation, from mineral rich fluids in a Brazilian seam to the skilled hands that calibrated each facet for maximum harmony. We invite you to consider how this transparent, naturally bi color, excellent polished, no enhancement ametrine can be the centerpiece of your personal story, durable enough for regular wear, elegant enough for a lifetime, and rare enough to be distinctly yours.
