One of the most important aspects of maintaining the beauty of a piece of jewelry over its lifetime is the amount of care put into its preservation. Depending on the material used to craft your ring, it is a good idea to not wear it while performing any strenuous work - including exercising, working on your home or any other heavy labor; blows to the ring may bend its prongs, the ring itself and could even chip your diamond.
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.
Keep all gold away from bleach, the reaction will make it brittle and destroy your jewelry.Be aware of heavily chlorinated pools also.
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.
Bring your rings in anytime for a free cleaning and inspection to keep your stones shining.
