How to Spot a Fake Diamond
Quick tests to separate diamonds from cubic zirconia, glass and moissanite.
At-home tests
Fog test: breathe on the stone — a diamond clears instantly. Read-through test: a loose round diamond placed table-down on text blurs the letters. Sparkle: CZ shows excessive rainbow fire.
Limits
Home tests can't detect moissanite or lab-grown diamonds. Use a professional tester or lab report for certainty.
