Questo gioiello ha fluorescenza
Fluorescence refers to a diamond's tendency to emit a soft coloured glow when subjected to ultraviolet light (such as a "black light").
Through a temporary excitation of electrons, it may deliver energy in the form of light.
According to the intensity of the refractive light, diamonds are classified into five fluorescence grades: None, Faint, Medium, Strong, Very Strong
Diamond are evaluated by using light sources which emit ultraviolet rays. Diamonds with high fluorescence may change their colour.
Diamonds with violet or blue fluorescence appear to have better colour, and those with a different colour may worsen .
Therefore, should you invest in diamonds, we suggest you to choose Null, Faint or Slight fluorescence (which does not affect the color).

Il taglio del diamante
Il taglio del gioiello scelto
Cut defines the number and shape of the diamond faceting towards the table size, the crown and the pavillon.
Cutting style depends on the size and shape of the raw diamond.�>
Brilliant Cut It is the most classical and the best cut. As the stone provides the best facets arrangement and a wider distribution of light., its value increases especially in case of investment. This diamond has 57 faceting and 58 on the girdle diameter.
Emerald Cut This is mainly a rectangular cut. It can be also a square shape. The cut of the diamond is made by steps. This means the stone already has several sequences of faceting (usually from 48 to 50), which look like a stair, have an extended shape and are arranged on four sides. The standard dimensions of a rectangular emerald cut, one carat, should be 7x5 mm.
Oval Cut - Its technical name is “brilliant cut oval shaped”, as it is comes from the traditional round brilliant cut. The oval cut was invented in 1960 by Lazare Kaplan. Oval brilliants usually have 56 faceting.
Pear CutPear cut is widely requested and is characterized by two brilliances: the round side is the most brilliant, whilst the light has a lower reflection on the top, as a consequence of the angle of the lower faceting, which do not exceed 40°.
Princess cut is more brilliant than the round brilliant cut. Its shape reminds the brilliant style with sharp edges. The cut is performed so to provide a square shape. Princess Cut has usually 76 faceting.
Baguette cut - It is a variation of the emerald cut. The baguette is also called " barchetta" and evokes the typical French bread: the shape is long and rectangular, with octagonal corners and 14 facets.
