We look forward to seeing you again!
Our Simpson Street Show open to both the general public and to wholesalers, while our Michigan Street Show is primarily wholesale (wholesalers, please remember to bring your TAX ID).
GMI specializes in beautiful crystals and minerals, such as quartz, amethyst, citirine, and many others. Come by if you’re looking for something beautiful or unique, or perhaps even specimens so large you can only find them here.
