Beautiful ribbon-like patterns of small black puffs with brush strokes merely hinting of a reddish brown background make this large Montana Agate cabochon a truly one-of-a-kind treasure. Sure to give inspiration!
Large Dendritic Montana Agate Designer Cut Cabochon
63.5 x 25.5 x 4.5mm
43.85 cts.
I cut this cab by hand and it's been polished to a high sheen both front and back with slightly rounded bottom edges for easy setting.
Sometimes referred to also as "Montana Moss Agate", this stone is reknowned 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.
