How to Find and Understand Pure Gold

Identifying pure gold is crucial when purchasing or verifying gold jewelry or items. Here are key methods to check gold purity:

• Check for Hallmark: Look for a hallmark from a trusted authority like BIS (Bureau of Indian Standards), LBMA, COMEX, PAMP Suisse, Perth Mint, Royal Mint, or other certifications. It indicates the gold's purity, usually stamped with karat value (e.g., 22K, 24K).
• Understand Karat System: Gold purity is measured in karats, where 24K is pure gold (99.9% pure). For example, 22K gold is 91.6% pure, mixed with other metals for durability.
• Visual Inspection: Pure gold has a bright, rich yellow color. Discoloration or dullness may indicate impurities or plating.
• Weight Test: Gold is dense. Compare the weight of your item to its size; pure gold feels heavier than alloys of similar size.
• Magnet Test: Gold is non-magnetic. If a magnet attracts the item, it’s not pure gold.
• Acid Test: Performed by professionals, this involves applying acid to a small scratch on the gold. Pure gold resists acid corrosion.
• Professional Appraisal: For accurate results, consult a certified jeweler or assayer who uses tools like XRF machines to measure gold content.

Note: Always verify with a professional for high-value items, as home tests may not be 100% accurate.
