Each diamond contains its own DNA. Innate characteristics composed of the stone’s dimensions, clarity, cut, shape and color.


Possibly, the cut is the most important parameter for the optical vision of the stone. A good cut produces more brilliance and sparkle. The existing cuts are: Ideal – Very Good – Good – Acceptable – Poor.

In Clemencia Peris we only work with the sizes – Ideal size and Very Good size – since they are the only ones that achieve an almost total reflection of the light. The other sizes greatly diminish the brilliance and, in turn, the quality of the diamond.


We choose diamonds in the D-H range, designated by the GIA as River, Top Weselton and Weselton quality. A range that guarantees a magnificent color to the naked eye.


Purity is measured by the clarity of the diamond and its internal or external inclusions. At Clemencia Peris we select diamonds with the following qualities: FL – IF – VVS1 – VVS2 – VS1 – VS2. We do not work with or recommend lower qualities as the stone could break due to many imperfections inside.


Carat refers to the weight of the diamond. To determine the value of a diamond, its carat is considered a primary factor. However, two diamonds of the same size can have two totally different values. It all depends on their quality.

GIA or HRD certified diamonds
