Amethyst Sage agate has been around for a few decades and remains extremely popular. Its popularity is due, in large part, to the beautiful purple and gold colors and manganese dendrite patterns running throughout.
Dale Huett of West Coast Mining owns the claim, near Denio, Nevada, where the material can be found. Although this material is abundant in the area, not all examples contain the purple hues everyone is after. The rich purple hue, which is commonly called the “grape jelly,” is the great appeal of this material. The translucent purple chalcedony that presents with flowering manganese dendrites is breathtaking. There are many color variations, like pale lilac and grey with wonderful dendritic patterns that make this material perfect for designing cabochons.
