What is the best way to store an engagement ring when not wearing it?

Most ring damage doesn't happen while you're wearing it. It happens after you take it off. The best way to store an engagement ring has less to do with the box you buy and more to do with the habit you build. A bent prong from a toss into a ceramic dish, a chipped diamond from three months rattling around in a pouch with other rings, a missing ring because you wrapped it in a tissue before bed and the tissue went into the trash. I spend a lot of bench hours fixing exactly these problems.

My answer: store it alone, dry, in something soft that holds it still. The habit matters more than the box. Pick one spot and never let the ring land anywhere else.

Storing the ring day to day

For the ring you take off to sleep, shower, do dishes, or workout, use a fabric-lined ring dish or a box with individual slots. Not the pretty ceramic dish by the kitchen sink. Ceramic is hard, prongs are soft, and the sink is a drain. A ring can survive three decades of daily wear and then lose its center stone because someone knocked it off the bathroom counter while reaching for a towel.

Keep it away from water, lotion, and steam. The bathroom is the worst room in the house for a ring you're not wearing. Steam and humidity don't do anything useful to rhodium plating, and they can loosen the bond in older settings that were never meant to live in a sauna.

Don't wrap it in a tissue. I've had two clients do that, and both lost the ring by throwing the tissue away. Don't pile it with other jewelry. Diamonds scratch gold, diamonds scratch other stones, and sapphires scratch sapphires. One ring per slot, one ring per pouch.

Long-term storage

If the ring is going into a safe, a drawer, or a bank box for more than a month, clean it first. Use warm water, a little dish soap, and a soft toothbrush, then dry it completely. Oils from skin and lotion trap moisture, and trapped moisture dulls the metal and can irritate the stone.

Then have the prongs checked. A ring can sit in a safe for two years with a worn prong, and no one knows until the stone is gone. I do this check in five minutes with a loupe. It costs less than a loose stone that fell behind a dresser.

Last October, a woman named Caroline brought in her grandmother's ring after storing it for two years in a zip-top bag with a damp cloth. The bag trapped moisture, and the 18k gold had a faint reddish oxidation that took me half an hour to polish out. She'd been told the bag was safe. It wasn't.

For long-term storage, use a dry fabric-lined box, add a little silica gel pack if you live in a humid climate, and keep a photo of the ring on your phone with a note about the setting. If you're using a safe deposit box, make sure your insurance policy covers the ring while it's there. Some homeowner's policies don't.

What not to do

• Ceramic or glass dishes with no padding.
• Plastic bags with any moisture inside.
• The little pocket of your jeans.
• A jewelry box where rings sit loose in one compartment.
• Any spot within arm's reach of a sink, drain, or open window.

I keep my own bench rings in a divided tray lined with felt. It sits on my dresser, not in the bathroom. If you only remember one thing: one ring, one spot, no exceptions.
