Turning a Customer Success Consultation Into Two Sales on Rapaport Trade

“We listed only 10 diamonds to test the platform and sold two in our first week. Selling 20% of our initial inventory that quickly definitely caught my attention.”

The Challenge

Buying and Pricing, but Never Selling

Mark Klein had used Rapaport Trade for eight years, primarily to price stones and source inventory for his store locations. In that time he had never listed a stone, so he was using only part of what his membership offers. 

Meanwhile, Klein’s Jewelry carries a substantial diamond inventory, and its sales depended on its traditional retail customer base. Diamonds could sit in inventory while waiting for the right customer to walk in. Mark wanted an effective way to put more of those stones in front of qualified buyers, but listing them was not part of how he used Rapaport Trade.

The Solution

Customer Success Guides Him to List His First Stone

A Rapaport Trade membership includes business consultations with a customer success representative. In one of those conversations, Mark was encouraged to list stones he had in stock so he could sell as well as buy. The representative sent him information on listing and had him upload a stone to try it out. 

Listing turned out to be simple. Mark uploaded his inventory quickly, with no complicated setup. Within a few days a buyer found his diamonds on Rapaport Trade, contacted Klein’s Jewelry directly, and the two sides completed the transaction.

A couple of days later, another member of the customer success team called to help him upload more stones. By then he had already sold two. Customer success consultations come with a Rapaport Trade membership to help members grow their business.

“The process was very easy. We were able to upload our inventory and get our diamonds listed quickly without a complicated setup.”

Results

Mark Klein listed 10 stones for the first time in eight years and sold 2 of them in the first week, generating approximately $6,000 in revenue. He quickly saw the value of selling on Rapaport Trade, checked that the rest of his listings were in order, and added more stones.

Just having a Rapaport Trade subscription is not enough. Members get the most from the platform when they use it properly. For eight years, Mark relied on Rapaport Trade for pricing and sourcing. Once he uploaded stones, buyers on the network could find his inventory, and two stones sold. Members who pair active listings with the customer success consultations included in their membership put the full power of Rapaport Trade to work for their business. 

“Both transactions went very smoothly. The buyers found our diamonds through Rapaport, contacted us directly, and we completed the sales efficiently. The entire experience was straightforward and professional.”
