What it is
A small dealer business that sources certified loose diamonds from wholesalers, often on memo (you pay only when a piece sells), then lists them online and sells to independent jewelers, designers and engagement ring shoppers.
Your first three steps
- Take a diamond grading course (for example through GIA) and learn to read lab reports
- Open accounts with a few wholesalers and ask about memo terms and minimum purchases
- Build a simple site or marketplace listings with lab-certified stones, and contact local independent jewelers to offer sourcing
Who pays
Independent jewelers and designers who need stones without holding stock, and private buyers looking for a ring stone at a fair price.
How it makes money
You earn the margin between your wholesale cost and your selling price on each stone, sometimes plus a fee for sourcing a specific stone on request.
Skills that help
- Grading knowledge (cut, color, clarity, carat)
- Negotiating with suppliers and buyers
- Building trust and clear communication
- Careful record keeping
Watch out for
- Anti-money laundering rules: check whether your purchase and sale volumes require a compliance program under federal rules for dealers in precious stones
- FTC Jewelry Guides on describing diamonds, including clear disclosure of lab-grown versus natural and any treatments
- Conflict diamond sourcing: check suppliers' policies and paperwork
- Jewelers block or inventory insurance for stones in transit and storage, as general liability alone may not cover them
- Sales tax registration and resale certificates: check with your state
- Fraud risk when shipping and taking large payments, so use insured shipping and secure payment methods
- Margins can be thin and stock can lose value, so keep inventory small at first
