As a soft and porous gemstone, turquoise is sensitive to chemicals, heat, and impacts, so a delicate and consistent care routine is required. Turquoise chip necklaces often feature natural, unstabilized stones that can be more susceptible to absorbing oils and liquids, which can cause discoloration.

Daily wear and cleaning
• To preserve your necklace, make caring for it a part of your daily routine.
• Take it off. Remove your necklace before showering, swimming, or washing your hands, and before exercising or doing any strenuous activity. The stone is vulnerable to impacts and chips, and porous stones can absorb liquids and sweat.
• Put it on last. Apply all makeup, lotions, perfumes, and hairspray before putting on your necklace. Chemicals and oils from these products can permanently stain or damage the turquoise.
• Wipe it down. After each wear, gently wipe the necklace with a clean, soft, lint-free cloth, such as a microfiber cloth. This removes surface dust and body oils.
• Clean gently. If your necklace needs a deeper clean, dampen a soft cloth with plain water and wipe the stones and clasp. For heavier residue, use a tiny drop of mild, unscented soap mixed with lukewarm water. Do not use chemical jewelry cleaners, ultrasonic cleaners, or steam cleaners, as these will damage the turquoise.
• Avoid soaking. Never soak your turquoise necklace in water, as the porous stone can absorb the liquid and become discolored.

Storage
• Proper storage will prevent scratches and other damage to your necklace.
• Choose the right container. Store your necklace in a cool, dry place like a drawer or cabinet, away from direct sunlight. A soft, fabric-lined jewelry box or a soft cloth pouch is ideal to protect it from dust and other items. Avoid humid areas, like a bathroom, and plastic containers that can trap moisture.
• Keep it separate. Store your turquoise necklace separately from other pieces to avoid scratches from harder stones or metals. Necklaces are best stored lying flat.
• Control humidity. Because turquoise can react to moisture and temperature changes, consider adding a packet of silica gel to your storage area to help control humidity.

When to seek professional care
• If you notice signs of damage, consider having your necklace inspected by a professional jeweler.
• Signs of damage. Be aware of issues such as oil or chemical stains, noticeable scratches, dull areas from sun exposure, or a rattling sound indicating a loose stone.
• Professional repair. A professional can help address deeper issues that can't be resolved at home. If the silver setting tarnishes significantly, a jeweler can clean it with chemicals without damaging the turquoise, which is difficult to do at home.
