Caring for an elegant necklace featuring turquoise and red gemstones (often coral or spiny oyster shell) requires gentle handling due to the porous nature of these stones.

Cleaning Techniques
Turquoise and red stones like coral are sensitive and can be easily damaged or discolored by standard jewelry cleaners.
• Gentle Wiping: For regular maintenance, use a soft, dry microfiber or cotton cloth to wipe away dust and skin oils after each wear.
• Mild Soapy Water: If the necklace is visibly dirty, use lukewarm water mixed with a few drops of mild, fragrance-free dish soap. Dip a soft cloth in the solution and wipe the stones gently—do not soak or submerge them, as water can seep into the pores and cause cracking or color changes.
• Rinsing and Drying: Use a clean, damp cloth (water only) to remove any soap residue, then immediately pat dry with a soft towel. Allow the piece to air-dry fully before storing.
• Avoid Machines: Never use ultrasonic or steam cleaners, as the high heat and vibrations can cause porous stones to shatter or lose their color.

Protection and Daily Wear
Because turquoise and red gemstones are relatively soft (ranking 5–6 on the Mohs scale), they are vulnerable to chemical and physical damage.
• Chemical Sensitivity: Apply cosmetics, perfumes, hairsprays, and lotions before putting on your necklace. These substances can be absorbed by the stones, leading to permanent discoloration.
• Environmental Factors: Keep the jewelry away from extreme temperatures, high humidity, and prolonged direct sunlight, which can dehydrate the stones and cause them to become brittle or fade.
• Activity Precautions: Remove the necklace before showering, swimming in chlorinated pools, exercising, or performing household chores.

Safe Storage
Proper storage prevents scratches from harder gemstones like diamonds or sapphires.
• Separate Compartments: Store the necklace flat in a soft-lined jewelry box or a separate fabric pouch.
• Anti-Tarnish Measures: If the necklace features silver settings, include an anti-tarnish strip in the storage area to prevent oxidation.
• Avoid Airtight Plastic: While some recommend plastic bags to prevent tarnish, others advise against airtight containers for turquoise as it may need some humidity to prevent dehydration. A cool, dry, dark environment is generally best.
