Diamond Care

Diamonds are renowned for their exceptional durability and are the hardest natural substance on Earth. While they are resistant to scratches and general damage, it is important to understand that diamond jewelry is often set in different metals, which can wear differently over time. Proper care ensures that your diamonds retain their sparkle and brilliance for generations to come.

Protecting the Diamond's Girdle

The girdle of the diamond—the outer edge—can be vulnerable to chipping if struck with a hard blow. This is why it's essential to choose a setting that offers sufficient protection to the diamond. A well-designed protective setting can safeguard your diamond from accidental impacts, ensuring it remains secure and intact.

Regular Professional Cleaning

While diamonds themselves do not require frequent cleaning, your jewelry may accumulate oils, dirt, and grime that can dull its appearance. It’s recommended to have your diamond jewelry professionally cleaned at least once a year. A jeweler can also inspect the setting during this cleaning to ensure that no stones are loose and that the prongs or metal work are still in optimal condition. Regular maintenance helps maintain the beauty of the diamond while also identifying potential issues before they become serious problems.

For more tips on professional cleaning, you can visit theGIA (Gemological Institute of America) website, where they offer a comprehensive guide to cleaning and caring for your diamonds.

Proper Storage

When not being worn, diamond jewelry should be stored carefully to prevent any damage. Keep your diamonds in a soft cloth pouch or a jewelry box lined with fabric to avoid scratches from other jewelry or hard surfaces. Storing diamonds separately from other gemstones is especially important, as certain stones (like sapphires or emeralds) are softer and can scratch the diamond.

Additional Diamond Care Tips

-Avoid Exposure to Harsh Chemicals:

Household cleaning products, chlorine, and even some cosmetics can damage the metal surrounding your diamond. Be cautious when handling cleaning solutions or lotions.

-Remove Jewelry During Physical Activities:

It’s advisable to take off diamond jewelry when engaging in activities like exercising, cleaning, or handling harsh materials, to prevent accidental impacts.

-Insure Your Jewelry:

Even though diamonds are tough, they are not indestructible. Consider getting your diamond jewelry insured to protect against loss or theft.
