The way light interacts with matter....

I am constantly overwhelmed by the beauty of crystals. This led me to become a mineralogist and I enjoy introducing people to extraordinary pieces of natural art made by the earth.

​

​

My family began mining and selling crystals when I was a teenager (Rocko Minerals) and that experience had a profound affect on me. My crystal intrigue led me to graduate school at the University of Arizona, Geosciences, where I studied mineralogy under the advisement of Dr. Robert T. Downs.

​

I host live crystal sales on Instagram via @exterra_crystals and @rocko_minerals.

​

I hope to inspire new collectors and continue to provide aesthetic specimens for like-minded enthusiasts!

​

​

Fun fact:

Earth has over 5000 mineral species (and counting)!
