18.23 Ct. Bi Color Ametrine from Brazil

There is a timeless quality to gemstones that carry both history and distinct character, and this exceptional bi color ametrine embodies that rare union of past and present. Ametrine itself is a gemstone born of South American geology, a marriage of amethyst and citrine that has fascinated gem collectors and jewelers for generations, and this particular stone continues that legacy with a clarity and poise that feel almost aristocratic. Cut into a classic emerald cut, a shape that has been associated with elegance and refined taste since the age of grand jewelers, the stone reveals its dual personality as bands of warm golden citrine flow into cool amethyst violet. The emerald cut enhances the clean, linear planes of the gem, allowing a patient, contemplative play of color that rewards the viewer with different expressions as it turns, much like relics of enduring design that grow more meaningful over time.

This magnificent example weighs 18.23 carat, and measures 17.41 by 13.76 by 9.60 mm, dimensions that give it a commanding presence whether set as a centerpiece in a ring or suspended as a pendant that rests against the heart. The gem is transparent, with a clarity grade of very slightly included evaluated at eye level, which speaks to a purity that remains remarkably unclouded when seen in ordinary lighting. Its color intensity is described as intense, a term that conveys saturation and vivacity without sacrificing nuance, and the excellent polish brings each facet to life with crisp reflections and deep windowed planes. The stone has been treated with heat to gently enhance tonal balance, a common and stable treatment that respects the natural identity of the crystal while elevating its visual harmony. Originating from Brazil, this ametrine carries with it the rich geological story of the region, and when set by skilled hands it becomes a wearable monument to that provenance.
