1. Store jewelry properly: Keep your American diamond jewelry in airtight containers or ziplock bags. This will prevent moisture from reaching the jewelry and minimize the chances of tarnishing or corrosion.

2. Avoid direct contact with water: Remove your jewelry before engaging in any activities that involve water, such as washing dishes, bathing, or swimming. Even though American diamonds are relatively durable, prolonged exposure to water can still damage the metal settings or affect the appearance of the stones.

3. Keep away from chemicals: Avoid exposing your jewelry to harsh chemicals, including cleaning agents, perfumes, hairsprays, and lotions. These substances can corrode the metal or cause discoloration of the stones. It's advisable to wear your jewelry after applying cosmetics and fragrance.

4. Regular cleaning: Clean your American diamond jewelry regularly to remove any accumulated dirt or oil. Use a soft brush or a jewelry cleaning solution specifically designed for delicate stones. After cleaning, make sure to dry the jewelry thoroughly before storing it.

5. Wear with care: Be cautious while wearing your jewelry during the monsoon season. Avoid wearing it while engaging in physically demanding activities or sports that may increase the chances of damage or loss.

Remember, even with these precautions, it's essential to handle your American diamond jewelry with care and be mindful of its exposure to moisture and harsh substances.
