Although diamond is known as the hardest material on earth, it still runs the risk of being chipped: a hard blow to the girdle (its middle) or culet (the pointy bottom) may damage it. Aside from this, however, diamond is essentially indestructible. Additionally, its not a good idea to wear your ring while sleeping - due to the prongs potentially catching on the mattress fibers and either tearing the mattress or pulling a prong off.

To ensure the longevity of your jewels, it's best to store it in a jewelry box or an enclosed area where there are no other metals, as this could scratch your item or wear down the metal and its prongs.
