There’s something truly enchanting about moonstone jewelry. Wearing it can feel as if you’re carrying a sliver of moonlight with you wherever you go. Its soft, luminous glow, often silvery, bluish or milky, is caused by a phenomenon called adularescence. This happens when light scatters between microscopic layers within the stone, creating a shimmer that seems to float just beneath the surface.
But as beautiful as moonstone is, it’s also delicate. With a hardness rating of 6 on the Mohs scale, it’s moderately durable but still prone to scratches and surface damage. Many moonstones also contain inclusions, especially ones called “centipedes” (don’t worry – not the bugs!), which are tiny thread-like fractures. While these can add character, they also make the gem more vulnerable to chipping. That’s why proper moonstone care (including knowing how to clean moonstone) is essential, especially if you want to preserve its signature glow for years to come.
The Process for Cleaning Moonstone: A Step-By-Step Guide
Part of what makes moonstone so captivating is its moody, misty appearance. But if it starts to look dull or murky, it might be time for a little TLC. A simple at-home cleaning routine can restore its natural shimmer and keep it looking its best. If you're wondering how to clean a moonstone ring, pendant or pair of earrings, the method below is safe and effective. Just follow these six steps:
Step 1: Gather Your Cleaning Supplies
Before you begin, make sure you have everything ready:
- A bowl of lukewarm water (not hot; heat can weaken moonstone)
- A mild, liquid dish soap (avoid anything harsh or antibacterial)
- An unused, soft-bristled toothbrush
- A clean, lint-free cloth (microfiber or cotton works best)
Step 2: Prepare a Soap Bath
Fill a bowl with lukewarm water and mix in a few drops of mild dish soap to create a light lather. Think of it as a gentle spa soak for your moonstone jewelry, not a deep scrub.
Step 3: Soak the Jewelry
Place your moonstone jewelry in the soapy solution and let it soak for two to five minutes. This helps loosen everyday buildups such as dirt, oils and lotions.
Step 4: Gently Brush it Clean
Use a soft-bristled toothbrush or clean cloth to gently clean around the moonstone and any crevices in the setting. Go easy; moonstone can scratch or chip if handled too roughly.
Tip for cleaning moonstones in gold or silver settings: Use extra care when cleaning moonstones in precious metals like gold or silver, as both the stone and setting can be sensitive to damage. Sterling silver may benefit from a quick polish with a designated silver cloth—just keep the polish away from the stone itself.
Step 5: Rinse Carefully
Rinse your moonstone jewelry under cool, running water to wash away any lingering soap. Be sure to plug the drain or use a mesh strainer, just in case things get slippery.
Step 6: Dry with Care
Pat the piece dry with a soft, lint-free microfiber or cotton cloth. Let it air-dry fully before wearing or storing it.
What to Avoid When Cleaning Moonstone
Harsh chemicals
Steer clear of bleach, ammonia, commercial jewelry cleaners, and even natural options like baking soda, vinegar or lemon juice. These substances are often too abrasive or acidic, which can erode the stone's surface or dull its shine.
Ultrasonic cleaners
The high-frequency vibrations in ultrasonic machines can jostle moonstones and exacerbate internal fractures, potentially leading to cracking or fading.
Hot water or temperature extremes
Sudden temperature changes can cause internal stress or worsen pre-existing inclusions.
Moonstone Care Tips
Beyond routine cleaning, follow these long-term care tips to maintain your moonstone’s natural beauty and ensure it stays in good condition:
Store Separately
Keep moonstone in a soft pouch, fabric-lined jewelry box, or its own compartment to protect it from scratches caused by contact with harder stones like diamonds, sapphires, or even some metals.
Remove During Activities
Take off moonstone jewelry when engaging in any activity that exposes it to moisture, chemicals, or impact—like showering, exercising, cleaning, swimming or gardening.
Put on Moonstone Jewelry Last
Make moonstone the final step in your routine. Cosmetics, perfumes, lotions, and sprays can leave a residue that diminishes its appearance.
Wipe After Wearing
Use a soft cloth to gently wipe your piece after each wear. This removes oils or moisture that can dampen the stone’s sheen over time.
Inspect Regularly
Watch for signs of wear, like visible cracks, loose prongs, or cloudiness. Natural inclusions in moonstones can worsen over time if ignored.
Schedule a Professional Check-up
Have a trusted jeweler clean and inspect your moonstone jewelry twice a year. They can assess its condition and catch signs of wear before it becomes a costly repair.
Avoid Prolonged Sun Exposure
Intense UV light can cause fading or color changes over time, especially in peach, gray or rainbow varieties.
