Image donation by mineral collector Robert Lavinsky

Robert Lavinsky, PhD, has donated his complete picture database on mindat.org (about 29,000) and all images from his own homepage irocks.com to Wikimedia Commons. He has also offered about 20,000 additional pictures from his archive to be used as needed.

We need help translating the description of all pictures, screening the pictures on irocks.com for missing pictures, and uploading them to Commons. You can read more about how you can help us here.

Highlights

If you are browsing Commons for the first time, you may want to start with Featured pictures, Quality images or Valued images. You can also see some work created by our highly skilled contributors in Meet our photographers and Meet our illustrators.
