“We sent CAD files for 12 ring SKUs on a Monday morning. All 12 physical samples arrived at our London office the following Friday. Cut quality matched the approved renders exactly. The IGI reports were accurate and the 18K gold hallmarking was correct on every piece.”

Creative Director · Fine Jewelry Brand · London, UK

“Better Star is genuinely vertically integrated — they grow the diamonds in-house, cut them, and make the jewelry in their own factory. The cost difference versus buying through trading companies is significant. We now source 100% of our lab-grown diamonds and settings from Better Star.”

Procurement Director · Jewelry Retail Chain · New York, USA

“We used the ODM service to launch our first diamond jewelry collection without carrying design risk. Chose 18 SKUs from their catalog, added our branding, and sold out in the first season. The quality and consistency matched what our customers expected at the retail price point.”
