Treasures Beneath Your Feet!



More About Earth In Sync

 An Earthly Celebration!

Eons ago incredible sequences of events happened deep underground to create beautiful minerals, fossils and gemstones. We celebrate the happy coincidence of trace minerals, heat, pressure and chemistry that affected the formation of unique crystal structures that resulted in beautiful mineral specimens and gemstones.

We're bringing you earthly art in mineral specimens, crystals, fossils, jewelry and lapidary - from finished pieces to rough. Many of our minerals are from old collections.

Check out the Artisans Gallery for hand-made jewelry, many pieces made from artists in the Midwest USA. This highlights agates and jaspers from all over the world - from Mexican lace agates and plumes, coprolight to moss agates, petrified woods and Wyoming jades.

We have teaching aids for geology, including books, hardness testing tools, and mineral ID kits - especially created for science teachers and home schoolers!
