Short answer: a great deal. In gold plated jewelry the gold layer is only a few microns thick, so how long a piece lasts is decided less by the plating itself and more by the craftsmanship behind it — how well the base metal was prepared, how evenly the plating was applied, and how carefully the piece was finished.

Four ways poor craftsmanship shortens a piece's life

Craftsmanship checkpoints before you commit to a supplier

• Ask how many production steps are controlled in-house, and whether plating happens at the factory or is outsourced.
• Request pieces from a current production run, not only showroom samples.
• Inspect edges, the inside of rings, and the back of pendants — the places where sloppy work hides.
• Confirm compliance reports (REACH, CE) and whether an SGS factory audit is available for review.
• Start with a small pilot order before scaling up.

How we keep craftsmanship consistent at Hengdian (HD) Jewelry

Our own factory in Shanwei Haifeng, Guangdong runs five production lines under one roof, and every piece passes through 14 controlled processes before packing — so preparation, plating, setting, and finishing are managed by one team instead of scattered suppliers. For 18K gold plating over brass we work to our own standard of 0.1–0.3 micron (our factory specification, not an industry-wide figure), and custom plating thickness is available on request. Our jewelry is lead-free, and nickel release stays within REACH limits. The factory is SGS-audited, with REACH, CE, and SGS compliance reports available on request. Holding this consistency across 40,000+ stock designs and 500+ monthly new designs works only because process control comes before output.
