COMMON QUESTIONS
Diamond marketplace & API FAQs
What is a B2B diamond trading platform?
A B2B diamond trading platform helps jewelry businesses find and source diamonds from trade suppliers. Some connect buyers with multiple sellers; others provide access to one supplier’s catalog. Compare inventory, account requirements, fulfillment, and website integration before choosing.
How do diamond APIs and data feeds work?
An API lets your website request supplier data such as stone specifications, pricing, and availability. A data feed imports inventory on a schedule. Your integration must manage markups, refresh frequency, certificates, images, and availability checks before an order is confirmed.
Does Stuller provide a diamond API?
Yes. Stuller’s Gem API covers certified natural diamonds, lab-grown diamonds, and gemstones. Its Product, Order, and Invoice APIs support additional workflows. Access requires an eligible Stuller account. Stuller recommends staging catalog data rather than using its APIs to load every storefront page.
Does Diamondsonline offer a diamond feed?
Diamondsonline advertises its DOL Diamond Feed for retailers. Contact the provider to confirm the feed format, access terms, supported inventory, and update frequency for your website.
What should I compare before choosing a platform?
Check the inventory you need, grading reports, supplier terms, returns, shipping, total costs, and access to product data. For an online store, also confirm image rights, update limits, order handling, and compatibility with your ecommerce platform.
