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, a diamond is essentially indestructible. Additionally, it's 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 longevity, it's best to store your jewelry 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).
For even more protection, stop by our store for a jar of jewelry cleaner! (Instructions for cleaning: Submere your ring into the jewelry cleaner and let it sit. Use the brush provided to gently clean away all dirt and debris. Submere the ring back into the cleaner and rinse off with cold water.)
