The Houston Gem and Mineral Society is dedicated to the study of earth science and related fields through education and activities. We have regular field trips that all HGMS members are welcome to attend, and we have a number of special events that occur throughout the year–either at the clubhouse or at members’ homes. This includes auctions of material (silent and live), sales of material, and swap events where hobbyists set up tables and sell or swap material–typically very inexpensively. These informal events have morphed into our Trade Shows, which may occur two or three times during the year. Our largest event each year is the Annual Show which occurs on the second weekend of November.
