How to Choose a Diamond

You can’t wait to wear a diamond on your ring finger. As each diamond is unique, its value can be determined by four criterias.

The four C’s in selecting a diamond

The cut

A diamond’s sparkle and brilliance and the way it reflects the light depends directly on the perfection of its cut. A round diamond gleams with 57 or 58 facets.

The color

Though diamonds may appear white, the majority of them have a slight coloration, most often yellow. The whiter the diamond, the higher its value. Colors are graded with a letter from D to Z, with D being a perfectly colorless diamond and Z being a diamond with a light yellow, grey or brown coloration. However, there are also colored diamonds in intense yellow, blue, pink and green. These fancy colored diamonds are very rare.

A diamond’s color can be altered by irradiation techniques, followed by a controlled heating. An irradiated diamond must always be clearly identified as such.

The diamond can contain faint traces of crystallization called inclusions that are most often invisible to the naked eye. In most cases, they don’t affect its beauty but they can impact its value.

A diamond’s clarity is graded as follows:

FL (flawless) No inclusions or blemishes are visible to a skilled grader using 10× magnification.
IF (Internally flawless) No inclusions and only blemishes are visible to a skilled grader using 10× magnification.
VVS1 and VVS2 (Very Very Small Inclusions) Miniscule inclusions are difficult for a skilled grader to see using 10× magnification.
VS1 and VS2 (Very Small Inclusions) Minor inclusions are visible to a grader with a moderately practiced eye using 10× magnification.
SI1 et SI2 (Small Inclusions) Inclusions are relatively easy to find under 10× magnification.  
I1 (Inclusion visible to the naked eye) Inclusions are obvious under 10× magnification but difficult to see with the naked eye.
I2 Large or numerous inclusions slightly affecting transparency and brilliance.
I3 Large or numerous inclusions distinctly affecting transparency and brilliance.

Weight (CARAT)

Diamonds are weighed in metric carats (1 carat = 100 points). The carat is divided into hundredths of a millimeter, also called “points”: thus, a diamond weighing 0.25 carats is equal to 25 points or 1/4 of a carat.

The price is not necessarily proportional to the weight because the larger the diamond, the rarer it is and the rarer it is, the pricier it is. For example, the value of a 2 carat stone is not equivalent to two times the price of a 1 carat, but much more than that.
