This is a Herkimer, NY mineral specimen that features herkimer diamond(not actual diamond but quartz that's crystal clear) druzy and mini herkimers, calcite and dolomite. Every direction that you turn this there's something different! There's several different color of druzy with some being iron stained and some with mini- Herkimers sticking out. The dolomite and calcite specimens are just as wonderful. This is truly a special piece that pictures don't do justice for.
