Quotazione diamanti: Regole per stabilire il valore e la qualità di un diamante da investimento.

The rules to grade the value and quality of an investment diamond.

The value of a diamond is determined by its quality characteristics, the “5C”, which are recognised worldwide.

Carat

The weight of a diamond is certified in carats. One carat (ct) equals 0,200 grams. The quotation is in hundreds of carats.

Color

The most important characteristic is the color. The price is fixed by the color. For the investment diamond we just consider the first five gradings.

Clarity

The internal characteristic of a diamond is the clarity. Due to the international policies, the clarity of a diamond can be determined with an aggrandisement of ten times the original stone.

To be an investment diamond the clarity has to be IF (Internally flawless).

Cut

The cut of a diamond can be made in different ways, but just the round brilliant cut with 58 facets (or 57 if the culet is excluded) has a worldwide recognition: 56 facets eight symmetric, 24 the pavilion and 32 the crown, + table, + culet. The proportion, polish and symmetry has to be Excellent, Very Good or Good.

Certificate

All investment diamonds, which we sell, are delivered with a certificate of guarantee, which is recognised all around the world.

The investment diamonds are graded respecting the international policies from gemmological institutes, which are giving the guarantee and are liable for the reported declaration on the certificate.

Their identification and grading is neutral, in fact they do not buy or sell diamonds. Three of these institutes are recognised worldwide: IGI (International Gemmological Institute) HRD (Hoge Raad voor Diamant, Antwerp) GIA (Gemmological Institute of America, New York).

We deliver our investment diamonds sealed directly from the gemmological institute, save from falsifications, with an identity card (diamond report) with the laboratory findings.

This gives an incontestable guarantee.
