What is the value of a diamond?
Understanding how to evaluate a diamond and knowing the real value of gemstone allows you to discover the beauty of Ubaldi jewelry products. All gemstones are defined by it’s Shape, Cut, Clarity, Carat, and Colour which are known as the four “C’s”. Personally from Ubaldi jewelery we guarantee that the diamonds used have purity characteristics above the average
It refers to the proportions and angles of the diamond.
It is a parameter based on scientific formulas, a well-cut gemstone will reflect light internally from a facet similar to a mirror to the other and reflect it and disperse it through the upper part of the diamond.
In essence, it is a test of fire and brilliance, which allows well-cut diamonds to position themselves higher on the Diamond Quality Pyramid than superficial or deep diamonds.
Precious stones cut too shallow or too deep disperse the light through the bottom or side, effectively losing brightness and consequently value.
Other features of the cut are based on the shape, for example square, pear, heart or round.
The round diamond, however, is the most symmetrical shape and reflects almost all the light that enters, and is therefore the most brilliant diamond shape.
This parameter identifies the presence of impurities in a diamond. Impurities or inclusions are natural presences in the diamond as fractures or minerals, which normally appear when gems form in the earth. At a careful analysis they look like small clouds, clouds, crystals or feathers. Greater clarity affects a better color and therefore increases the value of the diamond.
FL – Flawless
IF – Internally Flawless
VVS1 – Very Very Slight Inclusions (Visible under a microscope)
VVS2 – Very, Very Slight Inclusions
VS1 – Very Slight Inclusions (Visible by loupe)
VS2 – Very Slight Inclusions
SI – Slight Inclusions (Visible by eye)
S2 – Slight Inclusions
I1,I2,I3 – Included (Imperfect)
This value identifies the weight of the diamond, equivalent to 0.20 grams
This parameter identifies the degree of colorlessness of a diamond.
The colors of the diamonds are different and are classified in color scale, which goes from D (colorless) to Z.
We must however specify that the color differences have very slight nuances and it is complicated to distinguish the difference between, for example, an E and an F.
So we can say that color is often a matter of taste and above all of budget.
The ten most common forms of how diamonds are cut are given below and are: Round (Brilliant), Princess, Oval, Marquise, Heart, Emerald, Pear, Asscher, Cushion, Trillion, Baguette, Radiant.
