5.08 Ct. Bi Color Ametrine from Brazil

This exceptional, one of a kind, transparent 5.08 carat, emerald cut, bi color ametrine is a rare treasure offered exclusively by The Natural Gemstone Company. Hand selected for its exceptional balance of form and color, this gem measures 12.53 x 8.45 x 6.27 mm, and has been expertly faceted to maximize its elegant emerald cut geometry. The stone presents a dramatic and natural division of warm golden yellow and regal violet, with intense color intensity and an excellent polish that speaks to the highest standards of lapidary artistry. Clarity is eye clean when evaluated at eye level, ensuring a clear, luminous window into the gem that reveals its bi chromatic heart without distraction. Originating from Brazil and enhanced by careful heat treatment to stabilize and enrich its palette, this ametrine is transparent, substantial in size, and polished to a brilliance that will set it apart in any bespoke setting, and its rarity guarantees that only a discerning few will ever possess a stone of such character.

Under different lighting conditions this ametrine performs like a living spectacle, transforming with intent and mood. In bright natural daylight the yellow side opens with a sunflower clarity, while the violet side remains saturated and noble, the faceted step cuts creating crisp flashes that trace the gemstone edges with light. Under warm incandescent lighting the golden tones deepen into a honeyed glow, and the violet adopts a velvety, almost floral richness, the transition between the two colors becoming softer and more painterly. Under cool LED or fluorescent light the contrast sharpens, the violet taking on a cooler, more regal tone, while the yellow leans toward a clear, lemon brilliance, the facets acting like mirrors to intensify the bi color statement. In candlelight and soft evening illumination the gem becomes intimate and mysterious, the violet sinking into a deep, royal hue, the yellow simmering like molten gold, and tiny flashes from the polished facets mimic the movement of light across water. When set as a ring or pendant, the play of light will be affected by the wearer, as movements and angles will reveal alternating proportions of yellow and violet, allowing the owner to curate the gem s personality from moment to moment.

This ametrine is a bespoke offering, meant for collectors and connoisseurs who appreciate stones that combine rarity, provenance, and exceptional cut quality. Each cut facet and polished plane has been considered to honor the stone s natural bi color zoning, making it ideal for an elegant solitaire setting that showcases its emerald cut profile, or for a custom creation designed to dramatize its unique color split. For those who appreciate the broader spectrum of warm colored gemstones, we also carry and recommend pairing with opal type, Fire Opal, which provides a complementary burst of orange red play that enhances the golden notes of this ametrine. The Natural Gemstone Company curates stones like this one in strictly limited quantities, and this particular 5.08 carat specimen reflects both the geological rarity of Brazilian ametrine and the meticulous selection standards of our team. If you seek a piece that is both a conversation starter and a private indulgence, this transparent, eye clean, emerald cut ametrine, with its intense color intensity and excellent polish, awaits a bespoke setting and a discerning owner.
