How to Care for Gemstone Jewellery: Tips for Malachite, Quartz and More

Gemstone jewellery adds a vibrant, personal touch to any outfit. Whether you love the deep green swirls of malachite, the ethereal glow of moonstone, or the classic elegance of pearl, these natural stones require special attention to maintain their beauty. At Missoma, we craft our gemstone pieces with care, and with the right maintenance, you can enjoy them for years to come.

In this guide, we’ll share expert tips on how to care for your gemstone jewellery, including cleaning methods, storage solutions, and what to avoid. Whether you own a birthstone piece or a statement necklace, these practices will help preserve the colour, clarity, and shine of your favourite stones.

Understanding Your Gemstone: Hardness and Porosity

Not all gemstones are created equal. Some, like quartz and diamond, are hard and durable, while others, such as malachite and opal, are softer and more porous. Knowing the Mohs hardness scale can guide your care routine. For example, malachite (hardness 3.5–4) is sensitive to acids and scratches, whereas quartz (hardness 7) is more resilient. Always check the specific properties of your stone to avoid damage.

Porosity also matters. Porous stones like turquoise and pearl can absorb liquids, oils, and chemicals, leading to discolouration. Non-porous stones like quartz are less absorbent but still benefit from gentle care. Understanding these differences is the first step to proper gemstone jewellery maintenance.

• Check the Mohs hardness of your gemstone to determine its durability.
• Porous stones need extra protection from moisture and chemicals.

Cleaning Your Gemstone Jewellery Safely

Regular cleaning keeps your gemstone jewellery sparkling, but harsh methods can cause harm. For most stones, a soft, lint-free cloth slightly dampened with lukewarm water is sufficient. Avoid ultrasonic cleaners and steamers, as they can damage softer stones or loosen settings. For pieces like the The Meaningful June Birthstone Set | 18ct Gold Vermeil/Rainbow Moonstone, use a gentle touch to preserve the rainbow moonstone's delicate sheen.

If your jewellery needs deeper cleaning, mix a few drops of mild dish soap with warm water. Dip a soft brush (like a baby toothbrush) into the solution and gently scrub around the stone and setting. Rinse with clean water and pat dry with a soft cloth. Never soak porous stones like pearls or malachite—instead, wipe them with a damp cloth and dry immediately.

• Use only mild soap and soft brushes for cleaning.
• Avoid soaking porous gemstones; wipe and dry promptly.

Storing Gemstone Jewellery to Prevent Scratches

Proper storage is crucial to prevent scratches and tangles. Store each piece separately in a soft pouch or a lined jewellery box with compartments. Harder gemstones like quartz can scratch softer ones like malachite, so keep them apart. For delicate pieces such as the Lena Charm Choker | 18ct Gold Plated/Rhodochrosite, a padded box prevents the rhodochrosite from chipping.

Avoid storing gemstone jewellery in humid areas like bathrooms, as moisture can damage porous stones and cause metal tarnish. Silica gel packets in your jewellery box can help control humidity. Also, keep your pieces away from direct sunlight, which can fade the colour of some stones like amethyst and rose quartz.

• Use individual soft pouches or compartmentalized boxes.
• Keep away from humidity, sunlight, and extreme temperatures.

Wearing Gemstone Jewellery: Dos and Don’ts

To keep your gemstone jewellery looking its best, put it on after applying makeup, perfume, and hairspray. These products contain chemicals that can dull stones and damage metal. Remove your jewellery before swimming, exercising, or doing household chores. Chlorine, sweat, and cleaning agents can be particularly harsh on gemstones.

It’s also wise to avoid wearing gemstone rings or bracelets during activities that involve heavy impact. Stones like malachite and opal can chip or crack if knocked against hard surfaces. For everyday elegance with low risk, consider pieces with secure settings, such as the Harris Reed North Star Pearl Hoop Earrings | Gold/Pearl, which feature pearls protected by a sturdy hoop design.

• Apply cosmetics and fragrances before putting on jewellery.
• Remove jewellery before swimming, exercising, or cleaning.

Special Care for Popular Gemstones

Different gemstones have unique needs. For malachite, avoid any contact with acids (including lemon juice and vinegar) and never use ultrasonic cleaners. Simply wipe with a dry soft cloth. For moonstone, which is relatively soft, gentle cleaning with mild soap and water is best. Pearls are organic and very delicate—wipe them with a soft damp cloth after each wear and store them flat to prevent the silk thread from stretching.

Quartz varieties like rose quartz or amethyst are more durable but can fade in direct sunlight. Clean them with mild soap and water, and store in a dark place. For gold vermeil pieces with gemstones, such as The Andy Everyday Pearl Set | 18ct Gold Plated, Pearl, wipe the metal with a polishing cloth and the pearls with a damp cloth—never submerge the entire piece.

• Malachite: avoid acids and ultrasonic cleaners.
• Pearls: wipe after wear and store flat.
• Quartz: protect from prolonged sunlight.

When to Seek Professional Help

If your gemstone jewellery becomes loose, damaged, or heavily soiled, it’s best to consult a professional jeweller. They can re-tighten settings, replace worn prongs, and perform deep cleanings safely. For heirloom pieces or valuable stones, annual professional inspections are recommended to catch any issues early. Missoma offers guidance on care, but for repairs, always use a certified expert.

• Have loose settings repaired by a professional jeweller.
• Consider annual inspections for valuable gemstone pieces.

Caring for your gemstone jewellery doesn’t have to be complicated.
