Facteurs catholiques qui déterminent le prix des pierres précieuses: couleur et tournage

Posté le par Joyjy

The cut is the soul of diamonds. Only good cuts can make the brilliance of diamonds reach the best condition. Nowadays consumers are more and more aware of diamond cuts. Donc, the so-called Cupid cuts, Hearts On Fire, Lazare Diamond and other diamonds that emphasize excellent turners.

Relatively speaking, the turning workers of colored gemstones seem to receive less attention. En fait, the cutting of colored gemstones is also very important. Only a good turner can make the color of the gems more eye-catching, especially the higher the carat number, the more difficult it is to cut large gemstones. Because the bottom section must be arranged more perfectly and meticulously so that there will be no “leakage window” phénomène. The so-called leaked window means that there is a partial hollow at the bottom of the table, and you can see directly behind the gem like a window. This is because of the bottom of the gem. The facet arrangement is not perfect, so the light cannot be reflected back.

The evaluation of the quality of the turner is based on the polishing and proportion of the gemstone. The gloss of the surface depends on the quality of the polishing; and the perfect proportion will have good symmetry and emit the most beautiful brilliance.

In order to make the gems look larger, many colored gemstones deliberately cut the gemstone table to a larger size, or deliberately cut the gemstones to be flatter. En fait, this is not correct, because a poor proportion will reduce the gem’s brilliance, but will reduce the gemstone value.
