Buyer's Guide

3 Ways to Verify
Real Gold at Home

Look for the Hallmark

Every real gold piece has a karat stamp (10K or 14K). Use a magnifying glass — look at clasps, inside rings, or the back of pendants. Our pieces always have it.

Acid Test

Take your piece to any local jeweler. A nitric acid test confirms karat in minutes. We welcome this — and we're confident in every piece we sell.

Magnet Test

Real gold is not magnetic. If a magnet attracts your jewelry, it contains ferrous metals — not solid gold. Our pieces pass this test every time.
