10.65 Ct. Bi Color Ametrine from Madagascar

From the moment this ametrine was born deep within Madagascar, its story began as a quiet dialogue between fire and time, between iron and crystal. Buried in ancient volcanic veins, the quartz that would become this gem grew in a slow, patient rhythm, recording shifting temperatures and subtle chemistry as zones of purple and golden light settled into the same crystal. The Natural Gemstone Company works with trusted local partners to trace these origins, respecting the land and the communities who bring such rare pieces to light. When this rough was brought to daylight, its natural transparency and a remarkable, clean demarcation between amethyst and citrine tones told our cutters that something exceptional lay within, a stone that could carry both history and sentiment into a new life.

The cutting and shaping of this piece was guided by that inner promise. Our master cutter chose an emerald cut to emphasize the gem’s linear bi color, and to create a gallery of step facets that embrace both the purple and golden zones. The finished gem is a transparent 10.65 carat emerald cut bi color ametrine, with dimensions of 15.39 by 10.14 by 9.39 millimeters, faceted with care, and polished to an excellent finish. Its clarity grade reads very slightly included evaluated at eye level, a level of clarity that keeps the gem lively and honest, revealing its natural character without distracting from its brilliance. Color intensity is medium, and the piece has undergone enhancement heat treated to stabilize and accentuate its dual palette, a common and disclosed practice that helps this dramatic contrast sing when set.

As an engagement gem this ametrine tells a story that a traditional single tone stone cannot, it holds two colors as two qualities present in a lasting relationship, each color supporting the other. The purple of amethyst brings depth and calm, the golden warmth of citrine brings joy and energy, together they make a symbol of balance and unity. At 10.65 carats this gem makes a confident statement, yet the elegant proportions of the emerald cut lend refinement that flatters the hand and reads beautifully in both classic and contemporary settings.
