We host an annual Fall mineral, fossil, and gem show the weekend before Thanksgiving each year. The show includes exhibits and vendors selling minerals, fossils, jewelry and other items related to the hobby. In addition we have a children's booth just for kids 13 years old and younger where they can assemble a "Rock Hound Starter Kit" collection of minerals, rocks, fossils in an egg carton. In over two decades of shows, we have given away over 13,000 of the kits. These make a great start to a budding geologist's collection or start for a science fair project.  
This year will be our 61st annual show, November 16-18 at the Affton Community Center.  We have several great prizes shown above, scroll down to see descriptions of them!  Be sure to fill out an admission slip to have a chance to win one of these prizes. See the show flier on the right for details on the upcoming show.  Photos are from vendors at past shows.

Show Prize Descriptions

The Grand Prize - a 6" x 10" slab of beautiful purple amethyst crystals.  Amethyst is the purple variety of quartz and is used in jewelry and as decorator pieces.  Our prize comes with an iron stand which makes a dramatic statement in any decor.

Other Prizes

This 6.5" fossilized ammonite from the Cretaceous strata of Madagascar.  The shell has been sawed in half and polished to reveal the numerous chambers, many lined with yellow calcite crystals deposited during the fossilization process.  

The petrified wood is from the area around Ambilobe, Madagascar.  This area is extensively mined for petrified wood, such as this piece, that was deposited during the Triassic period, approximately 220 million years ago.  Nearly all of Ambilobe’s wood is from the Araucaria tree, a type of conifer commonly referred to as the Monkey Puzzle Tree.  This petrified tree round is 9 inches in diameter.

This is a beautiful, robin-egg blue colored specimen of chrysocolla which has replace sharp azurite crystals.  A replacement of one mineral by another that keeps the shape and form of the original mineral is called a pseudomorph.  The name pseudomorph literally means “false form”.  Chrysocolla and azurite are both secondary copper minerals.  This specimen is 2.75 inches tall.

Malachite is a commonly occurring, opaque, green secondary copper mineral typically found as botryoidal masses or crusts which often show banding in varying shades of green, much like agates.  Malachite also forms interesting stalactite groupings such as this.  Our stalactite prize is 4.75 inches tall.
