How to Connect a Wholesale Diamond Feed to a Shopify Store
What suppliers and retailers should agree on before connecting diamond data to an online selling experience.

A wholesale diamond feed can give a retailer a wider selection without buying every stone upfront. For a supplier, the appeal is making relevant inventory easier for retail partners to use. Both sides still need to agree on the details: a feed is a data connection, not a replacement for a commercial agreement.
Agree on access and the information to share
Start with the supplier's available connection method and the retailer's permission to use the data. Depending on the supplier and integration, a feed may arrive through an API or a file. Ask which fields are available, how often they change, which images and reports can be displayed, and whether prices are specific to the retailer.
From a wholesaler's perspective, the first conversation is often about the relationship rather than the technology. Which retail partners should have access? Are their prices or product ranges different? Who should they contact when a record needs correction? A shared understanding prevents a technical connection from becoming a confusing collection of exceptions.
- Identify the supplier contact and authorized retailer account.
- Confirm how product images, reports and prices may be used.
- Agree on the update schedule and how each party will report errors.
Make a sample catalog useful to a shopper
Review a small sample before exposing a large catalog. Check identifiers, shape, carat, measurements, grading information, currency and the status of each stone. Confirm how missing values are handled and whether the retailer has permission to use the supplier's photos. For GIA reports, the report number can be checked against GIA's Report Check service.
Choose a sample with the variety you expect in the live feed: different shapes, laboratories, price ranges and availability states. Make sure identifiers remain stable between updates. If the same stone is represented more than once or an image is missing, agree on how the retailer should recognize and handle the record instead of silently guessing.
Separate wholesale prices from the retail offer
The feed price is the starting point for a retail decision, not necessarily the price a shopper should see. Confirm the currency and whether a figure reflects the stone alone. Retailers can then review their markup, setting cost and other charges. Test a few examples together so a change in source pricing does not create an unexpected result in the storefront.
Discuss freshness and what happens after an order
A diamond may be offered through more than one channel. Ask when the feed last updated, how sold or unavailable stones are removed, and what to do if an update fails. Agree on the process for confirming availability and requesting a supplier hold. A status recorded in a retailer's system is not automatically a hold in the supplier's system.
Consider an ordinary failure: the retailer receives an order just after the supplier has sold the same stone elsewhere, but before the next catalog update. Decide who checks availability, how quickly the customer is contacted and whether an alternative can be offered. The right response depends on the supplier's process; no refresh interval makes that conversation unnecessary.
Bring the feed into the selling workflow
Once access and mapping are agreed, review how the retailer chooses which diamonds to display and applies retail pricing. Test a handful of records through the storefront and order process, including an unavailable stone and a changed price. With Gemtheon, eligible supplier data can be connected to a retailer's workflow; methods, fields and update timing depend on the supplier and setup.
After launch, give both teams a way to raise discrepancies and agree on a regular review. Check a few records against the source, investigate failed updates and revisit access when a retail relationship changes. Gemtheon's team offers free assistance with feed connections; bring a sample and the supplier's connection details to discuss the particular setup.
