n5901 - Square Back

An outstanding quartz crystal cluster from Arkansas.  This very beautiful cluster is called a square back because it formed on top of a calcite bed, which later weathered out leaving square cavities on the bottom.  There is a very light yellow tint on this very beautiful cluster due to included limonite.  Stands up on its own.  Size:  4 1/4" long x 2 1/2" wide x 2 1/4" tall.
