Montana Agate Free Form

These Montana Agates look 3D in composition they are so translucent and the
depth of the agate.

This free form cabochon measures 48mm x 19mm x 3mm, weighs 3.2 grams

The Montana Agate usually has an almost clear background color with embedded moss structures in varying shades of brownish red to black. When you get a real good formation or a nice limb cast many times the cabochon will Iris, which reflects a rainbow of colors. The background often will be milky or cloudy and sometimes white opaque, however when the dendrites or moss formations are in the right place they make a beautiful landscape or lacy like picture. It is really amazing the forms that this agate produces.

Most of these Montana agates are found in gravel deposits in the area of the Yellowstone River and its tributaries. This particular Designer Cabochon has wonderful dendrites and moss through out.
It is rare to cut a Montana nodule just right and find a lovely large area with no fractures and such a beautiful arrangement dendrites as this one. Most Rock Hounds agree that a good Montana Agate is one of their favorite.
