1. Gentle Cleaning: Clean turquoise jewelry with a soft, clean cloth. Avoid abrasive or harsh chemicals that can damage the stone.
2. Avoid Direct Sunlight: Turquoise can be sensitive to direct sunlight, which may cause color fading. Store your turquoise jewelry in a cool, dark place when not in use.
3. Keep Away from Chemicals: Turquoise is sensitive to chemicals and acids found in household cleaners, perfumes, and cosmetics. Remove your jewelry before using such products.
4. Avoid Contact with Water: While turquoise is relatively stable, prolonged exposure to water can affect its color and stability. Remove turquoise jewelry when swimming, showering, or doing dishes.
5. Storage: Store your turquoise jewelry separately from other pieces to prevent scratches and damage. You can wrap them in a soft cloth or keep them in a padded jewelry box.
6. Rehydrate Occasionally: Turquoise is a porous stone and may benefit from rehydration. Wearing your turquoise jewelry helps it absorb the natural oils from your skin, which can improve its appearance over time.
7. Professional Cleaning: For deep cleaning or if your turquoise jewelry becomes heavily soiled, it's best to seek professional cleaning by a jeweler who specializes in gemstone jewelry.

Remember that turquoise is a natural gemstone, and some color changes may occur over time, which can add character and uniqueness to your jewelry. Following these care guidelines will help preserve the beauty of your turquoise jewelry.
