A Russian demantoid of extraordinary 4.14 carats — a size that puts it in genuine collector territory, as demantoid of this weight is exceptionally rare. Cut as a round in the Russian style. At its heart is a horsetail inclusion of museum quality: a dense, fully formed radiating burst of golden-green byssolite fibers, sharply resolved and spreading across the entire center of the stone — as textbook a demonstration of Uralian demantoid’s signature as one could ask for. The color is a deep, dark green with olive tones, giving the stone weight and gravity. A demantoid of remarkable size with a horsetail that would hold its own in a reference collection.
