The Nature’s Trail Collection from Crystal Creek Gems is all based on Silicon Dioxide.  That is, if you will, dirt and sand.  The gems we use are in crystal form and inclue: 

Crystalline Quartz (clear crystals, amethyst, etc.)

Micorcrystalline Agate and Caledony

Micorcrystalline Jasper

Geodes

Microcrystalline Fire Agate

Agatized Fossils 

It’s very unlikely you would find any of these hiking our Appalachian Trail.  So we try to show places mostly in the USA where you just might. 

This belt buckle is Turitella Fossil from the Green River Formation, Wyoming.
