Loose diamonds are all different, none of them are the same. They are sold fairly quickly and so if you missed your chance on the loose diamond you want – you will be able to replace it with a similar one but it will not look exactly the same as the one you originally wanted as no two loose diamonds look 100% the same, similar to the human DNA.

In fact, if you look at loose diamonds before they are set – you might receive a diamond with more beautiful characteristics than buying ready-made diamond jewelry. This is because checking the quality of loose diamonds is much easier than the already set diamonds – especially for the details about the carat, the color, the clarity, the cut, and even the brilliance.
