Market Validation
Is this a real business?
Most gemologists work inside an existing business — store, lab, auction house
Two people doing this independently
David Bidwell — NY
No storefront · 100% B2B: jewelers, estate attorneys, resale platforms
Shelly Devine — Carmel, CA
Same bundle as you · physical location + 1stDibs marketplace
Neither playbook copies directly — St. Louis needs its own version.
