Just because a diamond is the hardest substance on earth does not mean it can’t be damaged. Diamond care is important for the beauty and longevity of your diamond. Be careful with household cleaners that may hurt your diamond jewelry. Bleaches, chlorine, and things like that, can actually damage the mounting, or the ring itself as well. They may even cause discoloration and pitting. Your diamond can also appear dull due to such things as hair spray and makeup. Even everyday wear and tear can have an effect too. So be careful with your precious stone.
An easy way to clean your diamond is to use a quality jewelry cleaning solution. If you don’t have that available, you can use warm water with a few drops of mild dish soap to clean your diamond. You then can use a new soft toothbrush (only used for cleaning jewelry) to get to the hard to reach places.
The wonderful thing about diamonds is that they never ever lose their beauty and brilliance once they're cut. You simply have to clean that diamond and you get that look that you had the day you fell in love with it. But diamond care and being aware will mean less trips to jewelers and less inconvenience.
