Free Loss Protection

To build loyalty, trust and security for your customers, each Black Box Gemstone comes with 1-year complimentary insurance through GemShield®. The coverage offers immediate protection against loss, theft, or damage.

  • Fill out the activation form for your customer and fax it to GemShield. Coverage is immediate upon receipt of the form. If a loss occurs within the free year, your customer will return to you for replacement. Stuller replaces the gemstone through you at no cost to you or your customer.

  • When the free year is up, GemShield contacts your customer and offers a personal jewelry insurance policy. They direct the customer to your store to assist them with the application, verify that the value is accurate, and have the jewelry inspected. This gives you an opportunity for another sale.

  • Renew your customer's policy and/or offer to insure the entire jewelry piece by becoming a GemShield Retailer. Stuller customers receive free enrollment. Call 800-932-3062.

What Customers are Saying

"Whenever I need to "wow" a client, especially in colored gemstones, Stuller's black box presentation always seals the deal. Nobody in the entire industry supplies such a professional lab report and presentation on your quality gemstones. I never lost a sale when using Stuller's red and black box presentations."
