The size of the diamond is the most important. You must mark the size of a diamond to know its value. The size of a diamond is calculated in carats, or how many points, 1ct (carat) = 100 points. And the corresponding level should also be marked. The value of a diamond is measured by its size, clarity, color and cutting. The second level is not bad, but I don't know how much you spent, and it's hard to tell you whether it's expensive or not.
