So of course you'll want it to always radiate as brilliantly as the first day you slip it on. Fortunately, the task of caring for your diamond is quite simple. Protecting Your Diamond Even though diamonds are the hardest substance known to man, a diamond will scratch another diamond. So it is important that jewelry not be stored together since it can be scratched or tangled. Also, diamond jewelry should never be worn while doing heavy work.
Points are vulnerable to chipping and even everyday activity can loosen a setting.
This is why it's important to visit a professional jeweler every six months to have your diamond's mountings and settings checked.
