The Calcite crystals on this specimen have very little damage. It is from the Sweetwater Mine Reynolds County, Missouri. The large crystal is nearly 3" tall and 1.25" wide. We stood the specimen on edge because of our lights, but this specimen sits flat on the parent rock base. There are interesting step ups and downs and a little cave that don't show well in 2d. These features make this specimen very visual. This specimen is loaded with crystals and a sprinkling of sphalerite here and there. It is well worth the $85 we are asking for.
