Our Inventory

Four Directions specializes in geology- rocks, minerals, and fossils- but we are more than just a rock shop! Our inventory changes regularly, but read below to learn more about our most popular items. If you are looking for anything in particular please do not hesitate to contact us.

Rocks & Minerals

We stock a wide variety of rocks, minerals, fossils, and semi-precious gems from around the world. These pieces range in form: polished spheres, standing freeforms, hearts, palm stones, tumbled, points and obelisks, slices and slabs, sculptures, wall hangings, etc. And of course we have natural crystals, rough, and raw stones in a range of sizes. Pricing depends on weight, quality, and relative rarity of the stone. We have dozens of stone varieties under $10, as well as larger or more rare and expensive specimens.
