Each case study below documents how MIRAMETAL actually produces one piece from the live catalogue – the specification, the production route it travels, the inspection it receives and the order terms that apply. Every figure on these pages is read from the catalogue or from the company’s own published operating facts. No client is named and no order volume is claimed.

How these pages are written
MIRAMETAL has been manufacturing jewelry in Guangzhou since 1990 – 30+ years of production for jewelry brands in international markets. The workshop is ISO 9001 certified and works to EU REACH and US CPSIA requirements. CAD design, mold-making, casting, stone setting, polishing, plating and quality control all run in-house, which is what keeps an approved sample and a bulk run on the same route.
Orders start from 1 piece and sampling runs 3-7 days after design approval. If you want the same treatment applied to a piece of your own, the OEM/ODM capability page sets out what you can specify, and Inside Our Factory shows the workshop.
