2016 Fall Swap and Auction - September 10-11, 2016

One of the great pleasures in the gem and lapidary world is visiting clubs during their annual shows.

The 2016 Northwest Arkansas Gem and Mineral Society Annual Fall Swap and Auction will feature a wide range of rocks, minerals, gems, demonstrations, handcrafted jewelry, fossils and supplies. Whether you’re looking for a bargain or just interested to see what lapidaries are doing, you can be sure of a warm welcome.

If you are already a lapidary club member in our area, why not organize an official club outing to our event and really make a day of it?

If you’re just browsing and not a member of any club, this is a terrific way to discover a little bit about earth science, geology and lapidary. There will be many subject matter experts on hand to answer your questions.
