Keep your jewelry dazzling with these expert gem-cleaning tips from some of the world's experts.

Roman Malakov Diamonds is a heritage jeweler specializing in the finest-quality diamonds and custom engagement ring designs in the heart of New York City's famous Diamond District. At Kaufman & Kaufman, they are a trusted source for rarities and sparkling necessities like diamonds-by-the-yard necklaces or pendants.

With three generations of diamond expertise, Roman Malakov Diamonds is the perfect resource for learning about one of the most important aspects of caring for your diamond engagement ring: proper cleaning. You should do this at least every six months at home or your local jeweler (have the prongs checked and tightened, if necessary, simultaneously). We thank Michael Malakov, the firm's product, for his contribution.


How do you clean a diamond ring? What's the best method for cleaning a diamond ring? 

A commercial-grade ultrasonic machine is a safe and most effective option. Just remember that stones can shake out if they've become loose, and without the proper equipment, it's possible to lose stones that fall out. Also, some diamonds have been treated with clarity enhancements or fracture-filled with glue, and the heat from the machine could melt away those components. So, the ultrasonic is designed for natural, nontreated diamonds. We recommend that you always inspect your diamond before determining the cleaning method by a professional jeweler.

How do ultrasonic cleaners work, and are they worth the investment?

They send sound waves through the water, gently loosening dirt and debris. I recommend getting one if you can afford it and have the room.

What method will be used if someone brings a ring to a jewelry store for cleaning?

Mostly ultrasonic with special soap and ammonia, plus polishing if needed. Also steam cleaners are utilized as well.


What advice do you give Kaufman & Kaufman readers about cleaning a diamond ring at home?

Make a simple solution of one-third Windex to two-thirds boiling water. Soak the ring for at least an hour if it’s filthy, scrub the jewelry gently with a soft toothbrush, and rinse clean. To get rid of the excess water, spray the ring with a compressed air duster, like the one you might use to clean a computer keyboard.

We have heard of toothpaste, mild dish detergent, and, in some cases, vinegar used to clean diamond rings. What’s your take?

No to toothpaste. I’ve never heard of vinegar as an option. Mild soap would be okay. 

What about the professional jewelry cleaners that some jewelry stores sell?

We hear they don’t work as well and don’t recommend them.
