Earth's Treasures was formed in 1985 by Rick Kennedy while he was a geology student at U.C. Santa Cruz. Originally mostly a field collector with an interest in minerals from the western United States, as the business has expanded, he has specialized in fine minerals and rare gemstones while keeping an affinity for classic localities including his favorite: The Benitoite Gem Mine.

Another aspect of Earth's Treasures business is specimen preparation and evaluation, especially of material from the Benitoite Gem Mine. Samples of our work will are here and most, if not all of the Gem Mine specimens you will see for sale on this site were prepared by Earth's Treasures.

Rick displays his "Rough and Cut" mineral and rare gem display at shows in the west and has given numerous programs to clubs and at shows on a variety of topics.
