3.50 Ct. Ametrine from Brazil

This exceptional bi color ametrine from Brazil is a rare offering that will appeal to the most discerning collector, a transparent 3.50 carat stone with dimensions of 12.18 by 8.42 by 5.43 mm that sits at the crossroads of classical elegance and modern rarity. Cut as a precise emerald shape, this gem reveals a gentle balance between warm golden tones and cool lilac to violet hues, a natural dichroism amplified by superior cutting and polishing. Evaluated at eye level with a clarity grade of very very slightly included, the stone reads clean and crystalline to the naked eye, allowing its internal color zoning and pure transparency to command attention. Light in color intensity and finished with an excellent polish, this ametrine has been carefully heat treated to enhance its tonal harmony while preserving its natural character. Each facet was chosen and executed to maintain the integrity of the gem, and as a limited piece within our curated selection, it represents an opportunity to own an ametrine of uncommon size and refinement. The Natural Gemstone Company presents this gem with full disclosure of its origin and treatment, offering collectors and designers a responsibly sourced treasure from Brazil.

What sets this emerald cut ametrine apart is its geometric faceting, a deliberate articulation of planes and steps that maximizes every photon that enters the stone. The elongated table and concentric step facets create a hall of mirrors effect, drawing light deep into the gem and returning it with layered flashes of color and brilliance. The emerald cut, with its parallel facets and truncated corners, emphasizes clarity and color transitions rather than scintillation, and when applied to a bi color material like ametrine, the geometry becomes a tool for storytelling, separating and blending hues with each subtle movement. Precision angles on the crown and pavilion guide light through the ametrine so that the golden and violet zones are not merely adjacent, they interact, reflecting across the stepped planes and producing a soft iridescence that shifts with viewing angle. The combination of excellent polish and careful facet alignment minimizes unwanted light leakage and enhances the stone's windowing effect, making the color zones readable yet mysterious. For a collector who values optical drama over flash, or for a jeweler crafting a statement piece that demands presence without ostentation, this cut offers a measured, architectural beauty that will outperform simpler cuts in both formal and intimate settings.

Owning this ametrine is to join a small circle of connoisseurs who seek pieces with provenance, craftsmanship, and personality. Because large, transparent bi color ametrines with such balanced zoning and an emerald cut of this quality are uncommon, availability is limited, and each one we release is treated as a singular offering. Whether you envision this gem set as the focal point of a bespoke engagement ring, a refined cocktail ring, or a minimalist pendant that lets its geometry speak, its robust dimensions and calming color play lend themselves to many interpretations. Our team at The Natural Gemstone Company can assist with custom designs that honor the stone's linear geometry, recommending settings that protect the facets while showcasing the step cuts and color alignment. We also provide guidance on metal choice and mounting style to ensure the gem sits with optimal light exposure, preserving its hall of mirrors effect and emphasizing the interplay between gold and violet. This is an invitation to acquire not just a gem, but a story piece, one that will be admired for its rarity, its exacting faceting, and the quiet confidence it imparts to whoever wears it. Owning this ametrine means owning a sculpted moment of light, a rare treasury from Brazil that places you among an exclusive few who recognize true gemological distinction.
