About LUMIDIAM B2B Gold Earring Manufacturer

Our Background

LUMIDIAM operates as the B2B fine jewelry division of Siu Sze Limited, a well-established Hong Kong jewelry manufacturer with decades of solid gold craftsmanship experience. For years, our parent factory has supplied finished gold jewelry to well-known retail brands across Europe, North America and Oceania, accumulating mature production, quality control and global shipping systems.

Our Core Positioning

We abandon full-category jewelry production and focus vertically on 14K & 18K solid gold inlaid earrings, serving only B2B commercial clients from the US and Canada. Three core business lines: ready stock wholesale, ODM original design customization, private label OEM manufacturing.
