SEP420 Septarian Cube

SEP420 Septarian Cube


Here is a beautiful larger cube carved from a Septarian Nodule from Utah.  The cube is cut flat on one corner to display to better show the different designs on the sides.  It has a great polish with an excellent mix of lovely Yellow Calcite accented by Brown Aragonite.  It measures approximately 3 3/4″ x 3 7/8″ and weighs over 5 pounds.  Very nice!
