TOUCH TABLE Rocks are the masses of material that make up the earth’s crust. Samples of the three major groups of rocks, igneous, sedimentary, and metamorphic are grouped on this table according to origin. This touch and learn table, sponsored by Casa de Oro Jewelers, enables kids and adults alike to pick up a rock, read a description, and learn more about our earth. Fossil specimens and descriptions are also on display along with a geologic time chart. There will be samples of our official (designated in 1969) Texas state stone, Petrified Palmwood, and the Texas state stone, Topaz.

DEMONSTRATIONS – watch experts work on lapidary and rock-related arts. See how a piece of rock becomes a piece of jewelry or a sculpture. Learn how rock specimens are identified.

SILENT AUCTION The auction normally runs on 1 hour intervals and gives the opportunity to bid on numerous gem and mineral specimens, slabs, and even miscellaneous pieces of used equipment.


  • Handouts with basic geological questions are given to the kids when they enter. They can complete these questions by visiting the Touch Table, the many vendors, and other educational displays. When their questionnaire is complete, it can be taken to the “Kid’s Wheel” for a free rock or mineral specimen.
  • Kids also can pay $.50 to spin the wheel and receive a rock or mineral specimen that coincides with the number pointed out by the wheel.
  • A fluorescent rock display is available for viewing for the young and old.


  • Valuable door prizes are given away throughout the show.
  • There is a special grand prize that is awarded by drawing at the end of the show from tickets of all who attended the show. You need not be present to win.
  • Buy a chance to win a mineral or fossil specimen to be offered by the GCGMS.
