When you think diamond, the first thing that comes to mind is a colorless or even yellow tinted stone. However, there are other diamond colors too, one of them being black. If you already knew that, and were looking for a comparison of black and white diamond engagement rings, you have come to the right place. Here, we will explain how black diamonds differ from white ones. First off, black diamonds are just as real as their white counterparts are, and have the same chemical composition. What is different about them is the structure, which causes them to absorb most of the light that falls on them, and appear opaque. Black diamonds also have more pores in them than white ones. They cannot be graded based on color the same way white diamonds are, since the black color derives from a unique crystal structure. Besides, the clarity of these stones cannot be graded in the same manner either. Natural black diamonds are relatively rare, and mined only in Brazil and Africa. This means most black diamonds are created in the lab by coloring other diamonds through heating, and hence they cost less.
