Turquoise is one of the most characterful stones in jewelry — but it is also one of the easiest to damage. It is porous, absorbs oils and chemicals, and can change color or crack if cleaned the wrong way. If you own turquoise jewelry, this guide keeps it blue, stable and beautiful.
Why Turquoise Is So Delicate
Turquoise is a hydrous phosphate mineral with natural pores. It absorbs water, soap, sweat, lotion and perfume, which can turn it green, cloudy or spotty. Heat and sunlight can dry and crack it. This is fundamentally different from hard gems like sapphire, so the standard jewelry cleaning method does not apply.
Stabilized vs Natural Turquoise
Most commercial turquoise is stabilized: the porous stone is impregnated with resin to harden and stabilize the color. It is far more durable and forgiving. Natural (untreated) turquoise is rarer, softer and more sensitive — it must be kept almost bone dry. Always know which you have; if unsure, treat it as the more sensitive natural stone.
The Safe Cleaning Method
- Use a dry or barely damp soft microfiber cloth — minimal water.
- Wipe gently; do not soak, even for stabilized stones.
- For silver settings, clean the metal separately with a silver cloth, keeping moisture off the stone.
- Buff with a dry cloth and let the piece air fully before storage.
What to Absolutely Avoid
- No soaking or water submersion — it darkens and can crack the stone.
- No ultrasonic or steam cleaners.
- No jewelry dips, bleach, alcohol or acetone.
- No prolonged sun or heat — drying causes cracks.
Daily Habits That Protect the Color
Turquoise absorbs whatever touches it, so perfume, lotion, sunscreen and skin oils are the main enemies. Put your turquoise on after doing makeup and hairspray, and take it off before swimming, bathing and heavy sweating. Store it separately in a soft pouch, away from direct sunlight. For other soft porous stones, our opal cleaning guide follows the same gentle principle.
When Turquoise Changes Color
Slight greening over years is common with natural turquoise and reflects the stone absorbing skin oils — many collectors find this patina desirable. Sudden blotchiness or cracks, however, signals water or chemical damage. If that happens, stop wearing it in water and consult a jeweler who specializes in soft stones.
The Bottom Line
Turquoise care is mostly about keeping it dry. A gentle wipe, no soaking, no chemicals, and cosmetics kept off the stone will keep your turquoise blue for years. Know whether yours is stabilized or natural — and treat natural pieces with extra caution.
Stabilization: What It Means for Your Turquoise
Most commercial turquoise is stabilized, and understanding that word prevents disappointment. Stabilization means the porous natural stone has been impregnated with resin to harden it and lock in its color. Stabilized turquoise is more durable, more color-consistent and far less sensitive to water than untreated material. It is the practical choice for rings and bracelets that see daily wear. Natural, unstabilized turquoise is rarer and softer, and it must be kept almost completely dry — it is better for pendants and earrings that do not meet water and sweat constantly.
Stabilized vs natural at a glance
- Stabilized: durable, color-stable, fine for daily wear.
- Natural: softer, more sensitive, keep dry, wear occasionally.
- When unsure: treat the stone as the more sensitive natural type.
Turquoise and Silver: Cleaning the Metal Separately
Turquoise jewelry is almost always set in sterling silver, and the two need different care. Clean the silver with a silver polishing cloth, but keep the polish away from the stone. If tarnish reaches the turquoise, do not try to polish it off — gently wipe the stone with a barely damp cloth and clean the metal around it. For the silver basics, our silver care guide applies to the setting. Keep cosmetics, sunscreen and perfume off the stone itself, and your turquoise will keep its distinctive blue for years.
