About The Hidden Gem
A rock, mineral, and lapidary shop built for collectors, families, and curious people who like their stones real, their info accurate, and their experience unhurried.
Grounded in the Foothills, Focused on Quality
The Hidden Gem is a locally owned shop in Loomis, CA, serving the greater Sacramento area with hand-selected stones, mineral specimens, petrified wood, and lapidary work. We’re here for the people who want more than a pretty display, they want to understand what they’re holding.
Some pieces come from the American West through rockhounding and field collecting, others come through trusted suppliers we’ve vetted for consistency and integrity. Either way, we choose materials with character, not just shine.
Our rule: if we wouldn’t put it on our own shelf, it doesn’t go on yours.

Local, On Purpose
We proudly serve Loomis, Rocklin, Roseville, Granite Bay, Auburn, and the surrounding Sacramento region. Whether you’re building a collection, starting a new hobby, or looking for something meaningful that comes from the earth (not a factory), you’re welcome here.
We keep it simple: honest sourcing, clean presentation, fair pricing, and real education. No pressure. No gimmicks.
Our Philosophy
Nature doesn’t cut corners. Neither do we.
Stones are slow miracles, shaped over time by heat, pressure, and chance. The Hidden Gem exists to give people a place to reconnect with that kind of time, the kind you can hold in your hand.
