Although diamond is known as the hardest material on earth, it still runs the risk of being chipped: a hard blow to the girdle or culet may damage it. 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.For even more protection, try this surefire method of keeping your ring looking its best: Grab a toothbrush and some dish soap, mixing it in a small bowl filled with hot water. Following this, take your ring and drop it in the bowl, letting it soak for about ten minutes. After that, take the ring out with tongs - as the water will be very hot - and gently brush it until all dirt has been removed. Finally, submerge the ring back into the bowl and rinse off the soap with cold water.
