Montana Agate - Designer Cut Cabochon

Beautifully patterned and richly colored premium Montana Agate cabochon with bold brushstrokes of rich ambers and browns evoking perhaps a western Montana landscape or a piece of modern abstract art. I've kept this cab on the thin side to compensate for the darkness and retain strong translucence. Ready for you to set into a stunning piece of jewelry or add to your collection.

I cut this cab by hand and it's been given a high mirror polish both front and back with slightly beveled bottom edges for easy setting.

Sometimes referred to also as "Montana Moss Agate", this stone is renowned for its patterns of golden to reddish brown to black inclusions and banding in a translucent chalcedony base. It can be found in gravel deposits of the Yellowstone River and traces its origin back to the volcanic activity in the Yellowstone area. The coloring within Montana Agate is due to the presence of manganese oxide (black), iron oxide (reddish browns) and other mineral oxides.
