7.85 Ct. Bi Color Ametrine from Brazil

From the riverbed to the jeweler's loupe, this 7.85 carat cushion shape bi color ametrine tells a story that begins in Brazil and ends as a refined jewel ready to wear. Formed over millennia as silica rich fluids cooled and crystallized, this ametrine carries the rare marriage of purple and golden hues that make the species so sought after. Carefully cut into a faceted cushion with a mixed brilliant style, its dimensions of 12.87 x 10.99 x 8.22 mm allow the purple and citrine tones to play across the table and crown with lively contrast. Evaluated at eye level as very very slightly included, the stone remains transparent and lively, its intense color intensity maximized by a precise mixed brilliant faceting plan, and its surface brought to an excellent polish that lets light return cleanly. The material received a controlled heat treatment enhancement, a gentle intervention that stabilizes and enriches its bi color zoning while preserving its natural character. At The Natural Gemstone Company we inspect each stage of this journey, from rough selection in Brazil to the final check under balanced lighting, ensuring that the gem you see is a faithful reflection of its origins.

This ametrine connects to a long heritage of use that celebrates balance and beauty, in the same lineage as the storied ametrines that once left the Anahi region to be treasured by collectors, and the citrines and amethysts that adorned ceremonial pieces and signet jewels across cultures. Historically, gems that combine calming purple and warming golden tones were chosen by artisans for rings and pendants that meant to unite clarity and abundance, contemplation and action. Worn as a focal stone, this cushion ametrine is ideal for a bezel or four prong setting that lets the bi color face forward, or for a bespoke design that embraces its two faces and turns them with the wearer. For those who appreciate provenance and craft, The Natural Gemstone Company offers this gem as a ready centerpiece or as the starting point for a custom commission, and our gem specialists can advise on metal choices and settings that honor both the material and its story. This ametrine arrives as more than a stone, it arrives as a compact tale of Earth, artisan skill, and heritage, waiting to become part of the next chapter on your hand.
