Losing a diamond from your engagement ring or another piece of jewelry can be devastating, and unfortunately, it happens more often than you'd think. As jewelers, we frequently replace lost diamonds, but we also want to help you prevent this from happening in the first place. With the right care and attention, you can greatly reduce the risk of losing your precious stone.

Here are 8 of the most common reasons diamonds fall out of their settings:

1. Damage to the Ring Setting

Accidental damage to your ring setting, especially to the claws holding your diamond, is one of the most common reasons diamonds are lost. Thin, worn-out claws are particularly vulnerable. If you notice any bending or breakage, it's time to consult a jeweler for repairs.

2. Damage to the Diamond

While diamonds are the hardest substance on Earth, they’re also brittle. A significant impact or force can cause a diamond to crack or break, leading to parts of the diamond being lost. If you think your diamond may have suffered damage, replacement is the safest solution.

3. Worn Ring Setting

Over time, even the best settings wear down. Precious metals like gold or platinum can thin, leaving claws that are barely able to secure the diamond. If you notice any wear, it's important to repair or replace the setting to avoid losing the stone.

4. Loose Diamond

Diamonds can become loose in their settings over time without the wearer realizing it. If you suspect your diamond is loose, try the "tap test." Hold the ring to your ear and tap it gently to hear if the stone shifts. If it sounds loose, a jeweler can re-tension the claws to secure it.

5. Incorrect Diamond Size for the Setting

If your diamond is too small or too large for its setting, it can lead to issues with security. A small diamond may not be held firmly in place, while a large diamond can put excessive stress on the setting, causing it to weaken. Proper sizing is essential for security.

6. Resizing the Ring

Resizing your ring can sometimes put the diamond at risk, particularly if it has a tension setting or diamond shoulders. After resizing, it’s important to have the security of the diamond checked to ensure it’s still properly secured.

7. Cleaning and Refinishing

Cleaning and polishing can sometimes disturb the setting, making diamonds loose. Ultrasonic cleaning, for instance, can displace settings, so it’s essential to have your ring checked afterward. Years of wear can also leave grime trapped in the setting, weakening the stone’s hold.

8. Displaced Claw

Even without visible damage, claws can become displaced over time, putting the diamond at risk of falling out. If you notice any movement in the diamond, it’s time for a visit to your jeweler. Try the tap test again to check for any loose stones.

The Best Way to Protect Your Diamond:

The key to preventing the loss of a diamond is regular maintenance. Have your ring settings checked by a professional jeweler at least once a year. Also, make sure you have adequate insurance coverage for your jewelry—because you can’t purchase insurance after the fact.
