There’s nothing like some shiny bling to polish off your look. Whether you’re into silver or gold, fine jewelry or cheap fashion jewellery, keeping jewellery in rotation for a long time requires proper care ― and a lot of us aren’t doing so well in that department.

We spoke to jewellery experts to find out everything you need to know about caring for your jewellery, including how to avoid damage, keeping it clean and when you should seek help from a professional.

You’d be surprised how many people have no idea what their favourite pieces of jewellery are made of.

Rachel Akmakjian, the director of jeweller relations at BriteCo, said, “Jewellery might be the only thing that you can literally wear every single day and if it’s properly taken care of, will be the same as it was the day it was purchased.” But proper care varies based on the material.

Fine jewellery is usually made of sterling silver, gold or platinum. These pieces are usually more expensive than fashion jewellery, and durable enough to last decades and be passed down to future generations ― but not without some care. Sterling silver contains copper, which can turn green if it’s exposed to chemicals, alcohols and sulphates found in common skin products like perfumes, oils, lotions and sunscreens. Gold itself won’t corrode, but if it’s mixed with copper, silver, palladium, zinc or any other alloy (as most clasps are, regardless of how pure the chain is), it can lead to damage.

Fine jewellery that features precious and semi-precious stones also need some love. Karina Brez, a third-generation jeweler, warns us that buildup can be bad for these gems. “Some gemstones can be damaged by perfumes and lotions. For example, opals can craze (create cracks that mimic a spider web) and the nacre (inner layer) of pearls can be worn away.”

Fashion jewellery, on the other hand, is made of cheaper base metals like brass and steel, making them much more sensitive and prone to tarnishing. Gold-plated pieces (base metals covered in a thin layer of gold finish) and gold vermeil (covered in a thicker, more durable layer of 18K gold) fall in this category, since it doesn’t take much to remove that thin layer of gold.

Surprisingly, some of your everyday activities could be detrimental to the shelf life of your pieces. If you’re the type who never removes your jewellery, you might want to reconsider.

A shower in regular water is OK for fine jewellery, but submerging a fashion piece in water is enough to make it tarnish, which is irreversible for these extremely fragile pieces.

After your shower, don’t rush to put those pieces on too soon! According to Jennifer Gandia, the co-owner of Greenwich St. Jewellers, when getting dressed, fashion jewellery should be the “last thing on, first thing off” since scented lotions and perfumes can contain alcohols that cause tarnishing.

Fine jewellery can withstand much more, but you still need to be intentional with care.

Brez suggests keeping your jewellery home when you go for a swim. We all know chlorine wreaks havoc on our hair, but she says we should be similarly wary of its effect on our jewels, especially anything with a clasp. Brez explains that even if the piece is made of 18k gold or platinum, “Those clasps can be a different metal and start rusting.” If your jewels do join you in chlorine or salt water, she highly suggests rinsing it immediately afterward to reduce the chances your clasp will rust or start jamming.

Even sleep can be rough on your bling. Akmakjian warns that body sweat can cling to our jewellery, causing it to tarnish ― and tossing and turning might make stones snag and loosen. “Sheets can pull the prongs away from the stones that they’re holding. It’s best to just take them off at nighttime and put them in a secured and safe location.”

Sweat can affect both your jewels and your skin. According to Brez, “Sweat is acidic in nature and can cause a reaction to metal — such as colour change and tarnish.” She notes you’ll mostly see these effects in your fashion or sterling silver jewellery. You’re less likely to have an issue with “high grade materials, such as solid 18K gold, which have a higher concentration of pure gold and are less likely to cause a chemical reaction with sweat.”

When your jewellery isn’t on your body, Brez suggesting storing it in a soft storage solution like a velvet or leather tray. She cautions against glass, especially if you have a gemstone, because “depending on the stone glass can scratch it or vice versa.”

To maintain its bright appearance, your fine jewellery probably needs more cleaning than you realise. A monthly cleaning for everyday pieces is ideal, but there’s no harm in cleaning daily if you think it’s necessary. Gandia suggests “The best way to know when it needs to be cleaned is typically to look at it.”

Special occasion fine jewellery pieces can be cleaned less frequently, since they likely aren’t exposed to any damage when they’re properly stored.

Gandia says you can clean your fine jewellery by soaking it in warm water and Dawn detergent for 5-10 minutes, to help loosen dirt and debris (one piece at a time, so the pieces don’t scratch each other). Gently scrub with a soft toothbrush to remove debris, then rinse with clean water.

Gandia told us to avoid submerging fashion jewellery in water, since it can lead to tarnishing. Instead, a toothbrush will help remove debris, and a slightly wet soft cloth, like an old T-shirt or microfibre towel, can be used for light buffing.

Akmakjian says microfibre polishing cloths are safe for most pieces, but other polishing cloths made of similar material are treated with “a type of a polishing rouge set within the cloth that can help buff out some of those fine, minor scratches.” If you choose this method, make sure you have the right cloth for the type of jewelry. Akmakjian notes, “There would be a different one for gold than there would be for silver.”

Even with a solid DIY cleaning regimen, it’s still wise to take fine jewelry to a professional annually for what Gandia calls a “spa treatment.” Gandia explains that professionals use hot steam and “put it into an ultrasonic cleaner, which will use a special solution and a vibration” for a deeper clean you can’t achieve at home. They can view your bling under a microscope to confirm the metal and make sure any stones are tight within their mounting.
