THE CUT
This is the most important of the 4 characteristics (or 4C) because, higher is the quality of the cut, better it is the combination between brilliance and fire of the stone. The cut is also the only directly influenced characteristic from the man. It's important to distinguish between the cut of the diamond, that it is a pure technical issue, and its shape, that preference of personal character is one. precision and the proportions of the cut determine the light amount that will be reflected. The cut to diamond in the round shape that more is known and maggiomente appreciated. Other shapes of shining cut include the drop, the marquise (lengthened with the appuntiti angles), the oval and the heart. An other cut is the emerald.

These are classify to you from letter H exactly L. the diamonds classifies M to you and beyond visibly they are coloured. Diamonds exist that introduce a pure coloration much fort, are much rare and they come defined “Fancy”. They can be rose, blue, green and intense yellow.
PURITY
Two equal diamonds do not exist to the world. Everyone possesses one its precise identity due to the presence of small carbon traces or of small remained crystals of various nature it imprisons to you during the crystallization process. Structural inclusions are called and been of the disomogeneità that comes considered of the “natural prints”. Their number, color, dimension and position determines the degree of purity of the diamond. However, the greater part of the inclusions is not visible to eye knot: disc of a valve to ten blowups is necessary one and the experience of jewelers.
