5.45 Ct. Ametrine from Brazil

From the heart of Brazil to the careful hands of our master cutters, this ametrine carries a story that begins deep within ancient volcanic soils, a slow creation of color and crystal under time and pressure. Mined in Brazil, this transparent bi color ametrine reveals a soft dialogue between amethyst purple and citrine golden tones, a natural split in the crystal that has been artfully preserved and enhanced by careful heat treatment. At 5.45 carats this cushion shaped gem presents itself as more than a specimen, it is a presence, a weight of value and rarity that you can feel when held. The mixed brilliant cut amplifies its bi color character, catching light and refracting pockets of warm honey gold and cool violet, while the medium color intensity gives the gem a versatile elegance that sits beautifully in both modern and vintage inspired settings. The clarity is graded as very very slightly included, evaluated at eye level, which contributes to the gem being perceived as eye clean and exceptionally pure to most observers, and the excellent polish finishes each facet with a mirror like surface that enhances sparkle and visual depth.

At The Natural Gemstone Company we celebrate gemstones that tell stories, and this 5.45 carat cushion ametrine speaks of thoughtful selection and precise craftsmanship. Measuring 13.12 x 9.42 x 7.22 mm the proportions offer an ideal table surface that showcases color zoning while maintaining lively brilliance from crown to pavilion. The mixed brilliant cut was chosen to balance scintillation and color separation, making the gem especially luminous for rings, pendants, and bespoke creations that demand presence without overpowering. Heat treated to stabilize and enhance tone, this gem retains its natural charm and remains a premium quality example of ametrine from Brazil. Whether mounted as the centerpiece of an heirloom ring, or kept as a collector piece, the substantial 5.45 carat weight and the gemologue grade details ensure a rare combination of beauty, durability, and investment calibre appeal. Allow The Natural Gemstone Company to bring this Brazilian treasure into your next creation, where its story of earth and expert hands can continue.
