 8X and Diamond Vault of Troy

Diamond Vault of Troy is proud to carry the 8x natural diamond. We have always prided ourselves on educating our customers. At no time in history has anyone made the standards of cutting so tight. Each of the 8 areas of the cutting process must be evaluated separately. We say 8x diamonds are five “X’s” better than all the rest.

If we think of professional race car drivers, cyclists, athletes aren’t they all trying to have the best performance? Why should we not do the same with a diamond?   8x does just that! All the light you see coming from a diamond entered the top of the diamond first. The caricature and quantity of light is determined by cutting. Most people have seen a diamond they will never forget. Some because they are bad and others that are just so beautiful that they are unforgettable. 8x is that diamond.

When you have consistency in cutting it is easier to understand the other areas of quality.
