Editorial policy

News and shop are separate

NaNa News is published alongside the Nana shop, but editorial decisions are made on news value only. Articles are not advertising and are not paid for by third parties.

Product links are labelled

When an article links to a gem or jewel we sell, the link is marked « Our shop ». We never present a product we sell as independent news.

Accuracy and sources

Facts are checked against primary sources (laboratories, auction houses, official data), which are cited at the end of each article. Gemmological claims about origin or treatment follow laboratory reports.

Conflicts of interest

The authors are also gemmologists and sellers. When a subject touches our own business, we say so in the article.
