Grape agate point

Grape agate is a type of agate with distinctive banding in shades of purple, blue, and white, sometimes with a mottled or dendritic pattern. It is formed when agate forms around a void in the rock and fills it with quartz, which is then stained by manganese and iron oxides to create the purple coloration. This is a cut and polished version that shows a nice display of the crystals corrugate together to form the iconic grape agate pattern.  Location:  Weight: 2.9 oz Size: 3.5X1 inches
