Calcite – The Most Collectible Mineral Species
Terry Huizing

As one might expect, success in collection building depends less on the random results of brief collecting experiences, but more on setting personal collection goals. When these standards are met, opportunities arise that often trigger specimen acquisition. My most productive collecting tool was the “silver pick” and it was carefully used in my travels. My standards for calcite are simple: specimens must be without damage; feature one of calcite’s five crystal forms; be twinned by one of calcite’s four twin laws; and, if not transparent, it must be colorful. These simple goals are not easy to achieve, so collections of this common mineral are not at all alike. Let’s take a quick look at what I look for when acquiring calcites. Being analytical aside, there’s always that one specimen that jumps out, captures your heart, and you just gotta have it!

Terry Huizing is a lifelong mineral collector who has indulged his interest in calcite by collecting on every continent except Antarctica, but typically much closer to home in the mines and quarries of the American Midwest. His childhood interests in minerals led him to pursue electives in mineralogy while completing a degree in chemical engineering from the University of Michigan. Gainful employment followed in Cincinnati, Ohio, where he interacted with the mineral community accepting volunteer responsibilities such as show manager (GeoFair), mineral curator (Cincinnati Museum Center), and consulting editor (Rocks & Minerals). Terry is a seasoned exhibitor, a published author, and an occasional speaker.
