How to Clean and Care for Your Pounamu Pendant

You’ve just unwrapped a piece of New Zealand greenstone, or maybe you’ve worn yours for years and never actually thought about whether you’re looking after it properly. Either way, you’re in the right place. 

Pounamu care is one of the easier things to get right. The stone is tough, forgiving, and in many ways, looks after itself. You just need to know the basics of how to clean and care for your pounamu pendant, and that’s what we’ll cover below.

 

Why Pounamu Care Is Simpler Than You Think

Pounamu is a hard, dense stone. It’s not going to scratch from everyday wear or lose its colour if you forget to clean it for a week. But it does have one real vulnerability: impact. Drop it on tiles or knock it against a concrete bench, and it can chip or crack. Outside of that, pounamu jewellery care is mostly about keeping it clean and wearing it often.

Here's something that surprises many people: the natural oils your skin produces actually help maintain the stone's polish. The more you wear your pendant against your skin, the better it looks over time. If you've been leaving it in a drawer, that's actually the opposite of what it needs.

 

How to Clean Your Pounamu

Day-to-Day Pounamu Cleaning

For regular pounamu cleaning, all you need is a soft, damp cloth. Give it a gentle wipe after wearing, especially if you’ve been active or the pendant has been sitting close to skin in warm weather. Once a week is a good rhythm if you wear it daily. That’s it. No special products, no soaking, no scrubbing.

When It Needs a Deeper Clean

Every now and then, usually after a few months of regular wear, your pounamu might start to look a little dull. You may notice lighter or slightly whitish patches on the surface. That's the stone drying out, and it's an easy fix.

Gently wash the pendant with lukewarm water and a tiny drop of mild soap. Nothing with harsh detergents or fragrance. Rinse it thoroughly to remove any soap residue, then pat it dry with a soft cloth straight away. Don't leave it to air dry, as water spots can form on the surface.

Once it’s dry, apply a very small amount of natural oil; coconut oil or olive oil both work well. Rub it gently over the surface with your fingers, leave it for five to ten minutes, then wipe away any excess with a soft cloth. You’ll notice the colour and sheen come back almost immediately. Most people only need to do this extent of pounamu care and maintenance two or three times a year.

 

What to Keep Your Pounamu Away From

This is where most accidental damage occurs. Pounamu care isn’t just about what you do to the stone. It’s about what you expose it to. Keep your pendant away from:

• Perfume, Hairspray, and Body Lotions: Apply these first, then put your pounamu on once they’ve dried.
• Sunscreen: It’s oily and chemical-heavy, and it builds up on the stone’s surface.
• Household Cleaning Products: Even mild cleaning products can affect the finish on your pendant over time.
• Chlorinated Pools & Spas: Take your pendant off before swimming.
• High-Impact Activities: Anything where the pendant might swing and knock against a hard surface.

If you’re browsing our pounamu necklaces and pendants and wondering which cord length to choose, keep in mind that longer cords tend to swing more freely. If you're leaning over a kitchen bench or sink regularly, a longer pendant is more likely to bump into something hard.

 

Storing Your Pounamu the Right Way

When you’re not wearing your pounamu necklace, store it in a soft pouch or lined jewellery box. This keeps dust off the surface and protects it from being scratched by harder pieces of jewellery sitting alongside it.

Don’t just drop it into the bottom of your bag. Pounamu may be tough, but losing it in a bag with keys and coins is asking for trouble.

Caring for the Cord and Binding

With simple pounamu jewellery care, the stone itself will likely outlast everything else, but the cord won’t last forever. Check it every couple of months, especially around the binding and the knot at the bail. Look for fraying, loosening, or any sign that the cord is thinning. A worn cord is the most common reason pounamu pendants are lost or broken.

If the cord looks tired, get it replaced before it breaks. Restringing is straightforward and inexpensive, and it’s far better than the alternative. Most jewellers who work with pounamu can handle a restring quickly.

 

Common Questions About Pounamu Care

Can I shower wearing my pounamu?

No, it’s best to take it off. Soap, shampoo, and conditioner can all build up on the surface and affect the lustre over time. Hot water and steam won’t damage the stone, but the cord binding can weaken if it’s constantly getting wet.

How do I restore the shine if my pounamu looks dull?

Gently wash your pendant under lukewarm water and mild soap. Pat it dry, then rub a small amount of coconut or olive oil into the surface. Leave it for a few minutes before wiping away the excess. The colour and depth should come back noticeably after just a single treatment.

Can I clean pounamu with jewellery cleaner?

No, when looking at how to clean and care for your pounamu pendant, note that most commercial jewellery cleaners are too harsh for pounamu. Stick to mild soap and water for cleaning, and natural oil if the stone needs conditioning. If you’re not sure, a soft, damp cloth is always the safest option.

What do I do if my pounamu cord breaks?

Don’t panic. As long as you haven’t lost it, the stone itself is almost certainly fine. Take it to a jeweller who works with pounamu to restring your necklace. Keep the stone somewhere safe in the meantime.

 

Pounamu Care & Maintenance Made Easy

Pounamu is one of those rare things that reward you simply for enjoying it. Wear it regularly, keep it away from harsh chemicals, give it a gentle clean now and then, and check the cord a couple of times a year. That’s the full picture.

There’s no complicated routine needed or special products to hunt down for pounamu care and maintenance. Just a little consistency and common sense, and your pendant will stay beautiful for decades.
