A rock shop in San Jose, California.
I've been selling rocks as Lithorium since 2025. I photograph each specimen where it sits, so you can see the piece you'll receive.
The shop
Each listing shows the piece you will receive. Most specimens are individual pieces, with one available.
The gallery also includes display specimens. These have a photograph and description; pieces available to buy show a price and checkout link.
What comes in the box
Each order includes a bonus specimen and a story handwritten in UV marker on black paper. Read it under UV light; the next order continues it. Choose science or metaphysical info cards with your rocks.
How a listing is written
I write the listings by hand. They cover mineralogy, how the specimens formed, and the occasional extinct squid.
Single specimens are identified by their observable properties: hardness, streak, luster, cleavage and crystal system, with the origin given where it is known. Identifications for curated boxes and rough lots are visual estimates, described as such in the listing.
Traditional and metaphysical associations are presented as cultural beliefs. Specimens are sold for collecting, display, and study.
