Wondering whether your jewellery is 22K or 18K? Start with the hallmark, then get it tested properly.
Read the hallmark
Look for the BIS logo, a purity grade like 22K916 or 18K750, and a 6-digit HUID. See BIS hallmark & HUID explained.
Home tests: limited
Magnet and float tests can catch some fakes but can’t tell 22K from 18K. Acid kits can damage the surface.
XRF: the reliable way
