An independent fact check

Every diamond “rule” was written by someone selling diamonds.

The salary rule, the rarity story, the investment pitch, the perpetual sale — diamond buying runs on claims that get repeated so often they sound like facts. Diamond-Check takes the ten you'll hear most, puts each one against the evidence, and stamps a verdict. Read the checks, then buy like someone who has.

How we check

Follow the money

Every claim gets traced to who profits from it. A "rule" invented by an ad agency gets graded like an ad, not like tradition.

Check the record

FTC jewelry guidance, grading-lab standards, industry survey data and market prices — verdicts rest on things you can look up, and each page shows its receipts.

End at your wallet

A verdict you can't act on is trivia. Every check closes with what it means for what you should actually buy — collected in the playbook.

Yes, this site earns affiliate commissions when you buy through its links — that's disclosed everywhere, and it never changes a verdict. Fact-checkers who hide their funding get fact-checked.
