About Buyjem

Last updated 8 November 2026

Buyjem is an independent English-language publication covering the jewelry, diamond, gemstone and watch trade. We track the prices, sourcing, retail, design, technology and brands that shape how jewelry is made, sold and collected.

What we cover

• Lab-grown: CVD and HPHT production, capacity, costs, grading and retailer adoption.
• Sourcing: mines, rough supply, licences, provenance and responsible sourcing.
• Retail and brands: store networks, e-commerce, earnings and consumer spending.
• Design, gemstones and watches: collections, colored stones, pearls, watch exports and luxury groups.

Who we are

Buyjem is produced by a 10-person editorial team based in Wuzhou, Guangxi. Our editors select stories, check key figures against the cited primary source and are responsible for what we publish. Meet the editorial team.

How we work

Our editorial workflow monitors publicly available sources and produces a concise English article for each development. Every article is reviewed by an editor before publication. Each article links to its original source in the Source block, and our structured data records that source asisBasedOn.

We use AI-assisted tools for translation, source monitoring and structured metadata. These tools support our editors but do not make publication decisions. Automated tools can still introduce errors; when we find one, we correct it and update the article.

Where an article contains interpretation, it is placed in a clearly labelled “Buyjem take” block and is grounded in facts stated in the article.

Media partnership

Buyjem is a media partner of theChina Photovoltaic Industry Association (CPIA), the national-level industry association approved by China’s Ministry of Civil Affairs.

Independence
