2. Type II Diamond - They carry less nitrogen impurities. With colors like pink, brown, and red, their formation is a result of plastic deformation and it is very rare. In Type IIb color varies from blue to gray, due to the presence of hydrogen or boron scattered within a matrix of crystal.
Diamond earring size is measured in "ct.t.w.", which is carat total weight. This system of measurement is for diamond studs. Each stud represents half of the pair's total carat weight. For example, if you select 1 carat earrings, the size of each diamond will be carat in weight. A comfortable and elegant earring size for adult women will be 1.5 ct.t.w. Of course, when you buy studs for small children, the size has to be much smaller as their earlobes are small and delicate, and large-sized studs might cause injury to their earlobes. Generally, 0.01-0.05 carat diamond studs are suitable for young children. A 0.05 carat stud would have a diamond that is approximately 1.8 mm in diameter.
When searching for your diamond, you should have a fundamental, if not thorough, knowledge of diamonds, their grades, and how those grades actually affect the gems appearance. A diamonds paper evaluation, including the certificate, can only be used as a reference to a diamonds true beauty. A certificate will not usually state whether or not the diamond has a bow-tie or fish-eye effect, nor will it differentiate visual from non visual inclusions without the use of a microscope. The easy rule of thumb to follow is this: if you are buying for investment reasons only, then paper evaluations and certificates is all that is required, however, if buying for yourself or a loved one, it is best to actually see the diamond first hand.
