n5902 - Rainbow & Square Back
An absolutely fantastic quartz crystal cluster from Arkansas that has a rainbow in the center point. 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. This outstanding cluster has a very light yellow tint at the base due to included limonite. Stands up on its own. Weighs 13 oz. Size: 5" long x 2 1/4" wide x 3" tall.
