Ever wanted to turn back the clock on your gemstone jewelry? Have it sparkling like new again? Trust me, it’s relatively easy to get that sparkle back.

Google ‘how to clean my jewelry at home’ and you’ll find yourself on Amazon for an ultrasonic cleaner or steam cleaner a minute later. Although it takes only a few minutes to clean your jewelry by pressing a button, there are downsides to these cleaners. There are gemstones you should NEVER put in an ultrasonic cleaner or steam cleaner.

The best way to clean your jewelry? Water and mild soap. 

But before we get into why ultrasonic cleaners aren’t our preferred option, let’s find out what ultrasonic and steam cleaners actually are. 

Ultrasonic cleaners use high frequency ultrasound waves to create microscopic bubbles in the water. These bubbles can reach every nook and cranny in your jewelry.

Ultrasonic cleaners are small in size and look similar to a rice cooker. It’s as simple as adding water into the cleaner, dipping your jewelry into the water, and turning it on to activate the ultrasound wave. You may want to add a cleaning solution for an even more effective deep cleanse. 

You don’t see this wave making visible ripples, but its tiny vibrations are abrasive enough to clean away dirt and grime. It’s not meant to remove tarnish if your silver jewelry is turning black. 

Soft gemstones, like opal, pearl, moonstone and turquoise can’t withstand ultrasonic cleaners. Heavily included gemstones, like salt and pepper diamonds and emeralds (a naturally included gemstone often treated with oil to fill internal cracks) should not be cleaned with an ultrasonic cleaner. The ultrasonic vibrations can affect internal flaws and crack the stone. Some ultrasonic cleaners heat the water up to 80°C. This can damage gemstones vulnerable to heat or temperature changes, like opal. 

The downside to ultrasonic cleaners is that those high frequency waves so effective in reaching the tiniest can loosen the gemstone in the setting. If you choose this method, be sure to check the setting of your jewelry after each wash. 

A steam cleaner uses high pressure steam to blast away dirt. It’s a quick and easy method, and similar to an ultrasonic cleaner, it uses water rather than harsh chemicals to do its job. It uses water’s amazing property - to break down into super tiny particles within a few seconds - to penetrate into the tiniest spots. 

The risk with steam cleaners is thermal damage. Since steam cleaners are basically boiling hot water, your metals and gemstones will be exposed to drastic temperature change. You can clean your jewelry within seconds with steam cleaners, but your jewelry must be able to withstand high heat.

Avoid cleaning jewelry with included gemstones with steam cleaners. Since included gemstones mean the host stone contains different minerals (the inclusions), under high heat, the two minerals can react differently to heat, causing fractures or internal cracks. 

Plus, high pressure steam is harsh AF. Soft gemstones may break under its pressure. 

Mild soap can be a gentle dishwashing soap, baby soap, or a gentle hand and body soap. 

If you’re not sure, use soap nuts, which grow abundantly in tropical and subtropical climates. Soap nut is traditionally used to clean anything from laundry to cutlery; from your head to toe. It bubbles like soap, making water more ‘slippery’, allowing it to penetrate deeper into the nooks and crannies. It’s also soft and safe enough to clean metals and gemstones. 

If your silver is heavily tarnished, you can add baking soda for a more aggressive wash. 

For tight corners with grimes, use a soft brush (a toothbrush offers good grip and good size bristles) and brush gently. Pat the jewelry dry and leave it to air dry. That’s it! As simple as washing your hands and therapeutic enough to turn it into a Sunday morning ritual. 

Now the question is - if it uses natural soap, does it mean you can clean it often? Not quite! Soap itself as well as the physical brushing is still abrasive contact over time. Once every 6 weeks should be sufficient, or depending on wear, tear and storage. 

Once you see a visible build up, make time for cleaning. The key for a sparkling clean gemstone is to clean it every now and then, not after your ring goes grinch and unrecognizable. 

If you bring your jewelry to a professional cleaner, make sure they’re aware of the internal condition of your gemstone. Remember not all jewelry cleaners are jewelers who understand the chemical structures of your gemstones. If you’re feeling doubtful about their knowledge of gemstones - leave. 

Loose setting often happens on jewelry with higher amounts of gold or silver. This is because gold and silver are soft metals.

Like any other precious possessions, jewelry does require maintenance. But I hope this blog post helps you choose the right cleaning method for your gemstone jewelry.
