Mohs Before Motors Rock Tumbler Shirt

Mohs Before Motors is a garment-dyed technical hobby tee for rock tumblers, lapidary artists, cabochon makers, agate collectors, jasper fans, and geology club regulars who know sorting rough matters before the machine ever starts. The artwork features an original hardness-sorting field board with invented rough specimens, compatibility lanes, scratch-test marks, and a simplified Mohs-style gauge for makers who separate softer practice stones from quartz, jasper, and agate before tumbling, cutting, or polishing.

This rockhound shirt is designed for people who love the bench-work side of stone polishing: checking material, planning a batch, avoiding mismatched rough, and chasing a better final polish. It makes a specific gift for a lapidary club member, rotary tumbler hobbyist, gem cutting student, geology hobbyist, or anyone whose workspace includes grit, slurry, slabs, and sorted stones.

All purchases help support rescued dogs and cats in need.
