How Can I Qualify to Become a Qualified Diamond Purchaser?

Rio Grande sells diamonds only to members of the jewelry trade who have been established by Rio as qualified diamond buyers. To qualify as a diamond buyer, you must meet one of the following three criteria:

  • be listed with the Jewelers Board of Trade; as a member, you automatically qualify
  • be able to provide us with a current copy of your business license AND two invoices or statements from another supplier in the jewelry industry
  • be a student currently enrolled in a jewelry-making course who can provide either a letter from your instructor on school letterhead or a copy of your coursework transcript.

We'd love to talk to you about how we can qualify your account for purchasing diamonds! Please fill out the form below and a member of our Gemstones Team will be in touch within 3-4 business days. Or, you can fax or email your qualifying information (listed above) to us. We look forward to being your diamond supplier!
