Our Latest Acquisition

Welcome to Pinal Gem & Mineral Society Website

Pinal County is booming and it's growth is projected to continue at a rapid rate. Within this mainly rural area are some of the most pristine and available sites for exploration and collecting. Located halfway between Tucson and Phoenix, the quaint City of Coolidge lies waiting for the rock enthusiast. The area is known for the many mines that dot the area and are a magnet for the collector. All we need is YOU!

The Pinal Gem & Mineral Society is resident in the Artisan Village of Coolidge at 351 N. Arizona Blvd in Coolidge, AZ 85128.

Coolidge is also the home of the Casa Grande National Monument and the surrounding desert is a mecca for rockhounding.

The Casa Grande National Monument in Arizona features the Casa Grande, a “Great House” of the Hohokam people that lived in the Gila Valley from approximately 300 CE to 1450 CE. The Casa Grande is one of the largest prehistoric structures ever built in North American and the structure’s purpose remains mysterious despite extensive archaeological excavation. Needless to say, it carries powerful intrigue for the modern-day visitor. Walk around the Casa Grande structure and wander the desert landscape that surrounds the site to expose yourself to the mystery of America’s ancient human history.
