107.55 Ct. Bi Color Ametrine from Ceylon (Sri Lanka)

A rare and commanding presence, this transparent 107.55 carat cushion shape bi color ametrine is an object of unmistakable desire, an emblem of refined taste and discerning ownership. It measures 29.89 by 29.20 by 19.32 millimeters, and is fashioned with a mixed brilliant cut that balances scintillation with broad color windows, enabling both intense sparkle and dramatic color play. Graded eye clean at loupe free observation, the gem displays vivid color intensity and an excellent polish that gives each facet a mirror like finish. Heat treated for optimal color balance, with its origin recorded as Ceylon Sri Lanka, this ametrine arrives to you with full transparency about enhancement, and with the pedigree of The Natural Gemstone Company behind it, a guarantee of provenance, craftsmanship, and rarity. That this stone exists at such an extraordinary scale and with such impeccable finishing elevates it from mere ornament to a singular statement piece, one that announces both achievement and a cultivated aesthetic sensibility.

What gives this ametrine its unmistakable signature is not merely the dramatic separation of golden citrine tones from deep amethyst purple, it is the language written within the crystal structure by nature itself. The gem carries a network of growth zoning and color banding that reads like a topographical map of geological time, delicate bands where iron distribution shifted during crystallization, producing a precise and painterly interface between honeyed amber and regal violet. These internal signatures are not obtrusive, indeed the stone remains eye clean, yet under magnification they reveal whispering fluid veins and feather like veils that catch light and diffuse it into a velvety luminosity. Minute crystalline seed inclusions occur as tiny pinpoint elements and the occasional sliver of trapped fluid, each one acting as a microcosm of the gem creator, a natural hallmark that confirms origin and authenticity. Together these inclusions and growth features form a fingerprint, a natural authentication that is impossible to replicate by synthetic means, and that imparts to the gem an individuality both scientific and poetic.

Cut with intention, the mixed brilliant facet scheme and generous cushion profile were chosen to celebrate and amplify the ametrine contrast, to allow the stone to breathe and the internal signatures to perform. Broad pavilion facets give depth to the darker amethyst zones, creating dramatic velour like fields that deepen when viewed face down, while a crown geometry of smaller, brilliant facets fractures light across the citrine heart, producing warm flashes of honey and topaz gold. The result is a living dichotomy, a jewel that alternates between sunlit warmth and twilight mystery as it turns, each facet revealing new relationships between color and light. The excellent polish acts as the final interpreter, smoothing facet junctions so that reflections are crisply resolved and the delicate internal veiling glows rather than obscures. In hand the gem feels substantial and perfectly balanced, its scale commanding rings, cocktail settings, or a bespoke pendant that will center a collection. Because the inclusions are subtle and respectful of the gemmaker s intention, they act as enhancers of character rather than detractors, imparting a depth and authenticity that high end connoisseurs prize above flawless anonymity.

To possess this ametrine is to hold a conversation between nature, masterful cutting, and personal expression, a piece that will both anchor an heirloom and stand alone as a badge of cultivated taste. The Ceylon provenance lends a narrative of exotic origin and exceptional geology, while the disclosed heat treatment speaks to responsible transparency, a standard of care that we maintain at The Natural Gemstone Company. For those who seek an investment in beauty the stone offers both rarity in size and a visual vocabulary that is unmistakably unique, the internal stratifications and minute inclusions acting as an archival signature that enhances long term desirability. We recommend settings that allow light to travel through the pavilion and crown, settings that celebrate the two tone drama rather than mask it, and professional cleaning practices that maintain the polish and brilliance. This ametrine is more than a gem, it is a declaration, a collectible of singular charm and scientific interest, and an opportunity to claim an object whose natural signatures will remain a private language between the owner and the stone for generations to come.
