n6103 - Square Back
A fantastic square back quartz crystal cluster from Arkansas. This stunning 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. The 2 largest points have a yellow tint due to an inclusion of yellow limonite. Stands up on its own. Size: 3 5/8" long x 2 3/8" wide x 1 3/4" tall.
