Diamonds are the hardest substance on Earth, but they are not indestructible.By taking proper care of your diamond ring, you can keep your ring looking as stunning as the day you received it.

1. Clean your diamond ring regularly

Regular cleaning is essential to maintain the brilliance of your diamond ring. You can clean your ring at home using a mild dish soap and warm water. Soak your ring for about 20-30 minutes, gently brush it with a soft toothbrush to remove any dirt or debris, and rinse it thoroughly. Avoid using harsh chemicals or abrasive cleaners, as they can damage the metal or the diamond itself.

2. Avoid wearing your diamond ring during certain activities

While diamonds are durable, they can still be damaged by certain activities. It's best to remove your diamond ring when engaging in activities such as gardening, exercising, or cleaning. These activities can expose your ring to chemicals, abrasive materials, or impact, which can potentially harm the diamond or the setting.

3. Store your diamond ring properly

When you're not wearing your diamond ring, it's important to store it properly to prevent scratches or damage. Keep your ring in a soft pouch or a separate compartment in a jewellery box to avoid contact with other jewellery pieces. Avoid storing your diamond ring in direct sunlight or extreme temperatures, as they can affect the colour and clarity of the diamond.

4. Get your diamond ring professionally inspected

Even with proper care, it's recommended to have your diamond ring professionally inspected at least once a year. Nnamdi The Jeweller will check the prongs, settings, and overall condition of your ring to ensure everything is secure and in good shape. We will also clean your ring using professional tools and techniques, restoring its brilliance and luster.

5. Consider getting insurance for your diamond ring

Accidents happen, and losing or damaging your diamond ring can be devastating both emotionally and financially. Consider getting insurance for your ring to protect your investment. Insurance can provide coverage for loss, theft, or damage, giving you peace of mind knowing that your precious ring is protected.

By following these expert tips and tricks, you can ensure that your diamond ring remains a symbol of love and beauty for generations to come. Remember, proper care and maintenance are key to preserving the brilliance and sparkle of your diamond ring, allowing it to shine as brightly as your love.

Natural vs Lab-Grown Diamonds

Lab-grown diamonds are composed of the same chemical structure and are physically identical to natural diamonds. Both our Natural and Lab-Grown diamonds are selectively sourced and certified. Lab-grown diamonds cost less and are a responsible choice as they do not require any diamond mining. Naturally-mined Diamonds are classically considered a better store of value.
