How to Care for Natural Stone Jewelry: A Complete Guide

Natural stone jewelry is remarkably durable, but every stone — amethyst, opalite, mahogany obsidian, tiger's eye — has its own hardness, porosity, and personality. Treat them well and a pendant becomes a piece you wear for decades. Ignore the fundamentals and even the toughest gemstone dulls, chips, or loosens long before its time.

This is the same routine we recommend to every customer who picks up a hand-strung necklace from the studio. It works for heirloom stones and everyday pieces alike.

Why natural stones need different care than metal jewelry

Unlike solid gold or sterling silver, gemstones are crystalline — often porous, sometimes soft, and sensitive to pH and temperature. On the Mohs hardness scale, common jewelry stones range from opalite around 5.5 to amethyst at 7. Anything below 7 will scratch against everyday grit.

• Chemical exposure — perfume, lotion, chlorine, and cleaners cloud porous stones like turquoise and moonstone.
• Physical abrasion — stones stored loose scratch each other; softer stones lose polish first.
• Thermal shock — hot-then-cold water, or a sunlit car, can fracture stones from the inside.

The daily routine

1. Put jewelry on last, take it off first. Perfume and product should be absorbed first.
2. Wipe stones after wearing. A lint-free microfiber cloth removes skin oils before they etch the surface.
3. Never sleep in it. Cords fatigue and clasps bend against pillows.
4. Remove before water. Especially chlorinated pools and salt water.
5. Store each piece separately in a soft pouch or lined tray.

How to clean natural stone jewelry safely

For most pieces the safest cleaning method is also the simplest. You don't need commercial cleaner, ultrasonic machines, or steam — most cause more harm than good on porous or adhesive-set stones. Our full at-home cleaning walkthrough covers each step in detail.

The gentle warm-water method

1. Fill a bowl with lukewarm water and a drop of fragrance-free dish soap.
2. Submerge for 30–60 seconds — never soak porous stones longer.
3. Brush the setting gently with a soft-bristle toothbrush.
4. Rinse under a slow stream of lukewarm water.
5. Pat dry and lay flat for at least two hours before storing.

Skip water entirely for these

• Turquoise, malachite, lapis lazuli
• Opal and opalite
• Pearls, coral, amber
• Any glued or resin-set piece

Storing natural stone jewelry

Where you store a piece matters more than how you clean it. See our full storage guide for setup — the short version is cool, dark, dry, and separated.

Stone-by-stone quick reference

• Amethyst (Mohs 7) — durable, fades in direct sunlight.
• Opalite (Mohs 5.5) — dry cloth only; see opalite vs. moonstone.
• Mahogany obsidian (Mohs 5–6) — glossy, chips if dropped.
• Tiger's eye (Mohs 6.5–7) — tolerates gentle water.
• Rose quartz (Mohs 7) — fades in UV.

When to bring a piece back to the maker

Watch for fraying cord, a shifting stone, a lazy clasp, or dullness that won't clean off. All repairable — cheaply, if you catch them early. Any piece from our studio can be restrung or re-set at cost via our contact page.
