Diamond is the hardest naturally occurring material on Earth, but that doesn’t mean you don’t have to care for your diamonds properly. Like anything else, they can be scratched, chipped or lost. That’s why it’s important to know how to properly clean and care for your diamond, whether you plan to sell it or not. If you’re looking to sell your diamond jewelry, you’ll fetch a much higher price if the stone is undamaged, clean and sparkles like new. Even if you aren’t looking to sell, these tips will help you make sure your jewelry looks as beautiful as it did the day you got it.
