Take care of light and heat  :- Prolonged exposure to light and heat can have a negative effect on your jewellery. Certain gemstones are especially vulnerable to heat, while other jewels might bleach under the sun.
Stay away from chemicals :-Â Even daily chemicals such as hairspray, perfume, cosmetics and more can discolour precious metals, such as gold, silver and platinum. They can also damage other items such as pearls.
Store Them Carefully :-Â Diamonds need to be protected not only against getting lost or being stolen, but also against damage. When a diamond rubs against another diamond, the gemstones can scratch each other.
