Why is Mercury harmful to gold?

Gold is more than just a precious metal in South Asia. For many families it represents memories emotions savings and family traditions.

Gold jewellery is often passed down from one generation to another making it valuable both financially and emotionally. However many people do not know that contact with a small amount of mercury can seriously damage their gold jewellery.

Gold is generally resistant to air and moisture but mercury is different. When mercury comes into contact with gold the two metals can mix through a process known as amalgamation.

This reaction can change the appearance and structure of gold.

Why is Mercury dangerous for gold?

Mercury is considered harmful to gold because it can mix with the metal and form an amalgam.  This may damage the jewellery’s surface and affect its structure.

After contact with mercury gold may lose its natural shine and develop white or grey marks.  In severe cases the affected jewellery may become weak and break easily.

Mercury can be found in some older thermometers certain medical equipment and a few industrial products.

Therefore accidental contact with mercury can become a serious problem for people who keep gold jewellery at home.

What should you do if Mercury touches gold?

If you suspect that mercury has come into contact with your gold jewellery avoid cleaning it yourself. Do not use heat or fire to remove the mercury.

Heating mercury can release dangerous vapours that may harm the lungs brain and kidneys when inhaled.

Instead keep the jewellery away from other household items and seek advice from a qualified jeweller or a professional who can safely handle mercury contaminated materials.

Why does some gold jewellery turn black?

These added metals may react with air moisture sweat and chemicals over time causing the jewellery to become dull or dark. However white or grey marks alone cannot confirm mercury contamination. If your jewellery changes colour or becomes damaged have it checked by a professional.
