According to the latest report from the Consumers Association, there have been many "high-purity silver" fraud cases recently. Scammers take advantage of consumers' lack of understanding of silver to sell silver-plated or adulterated silver jewelry at high prices. Special reminder:
1. When shopping for silver jewelry online, choose a merchant that offers "seven-day no-questions-asked returns"
2. Be extra vigilant if the price is significantly lower than the market price.
3. Require merchants to provide formal testing certificates
4. Testing recommendations from professional organizations
For higher value silverware or silver coins, it is recommended to send them to a professional institution for testing. Major domestic testing institutions include:
| Organization name | Test items | Fee reference |
|---|---|---|
| National Gold and Silver Products Quality Supervision and Inspection Center | Ingredient analysis | 200-500 yuan |
| Local quality inspection institutes | Basic testing | 50-200 yuan |

Real silver is easily oxidized and turns black, which is normal:
1. Avoid contact with perfume, sulfur and other substances
2. Store in a sealed bag when not wearing
3. Slight oxidation can be treated with silver polishing cloth
4. For severe oxidation, professional silver cleaning water can be used
Through the above methods, I believe you have mastered the basic skills of identifying the authenticity of silver. Remember, be vigilant when purchasing valuable silver products and don’t go for cheap. In case of suspicious circumstances, it is recommended to seek professional help immediately.
