The value of a diamond is based on the following four C’s
Carat - Refers to the weight of a diamond
The carat weight of a diamond is probably the most essential factor when understanding the value of a diamond.
A carat weight (1.00 carat = 100 points) is the standard unit used to measure and define its weight.
As the carat weight increases so does its rarity and its value.
Colour - Refers to the degree of which a diamond is colourless.
The colour of a diamond is graded from D to Z, most buyers are interested in the white range, as a diamond size increases its
colour becomes more noticeable. Sought-after colours with the highest value are in the D-F range (colourless) a
difference between one colour grade to the next is almost unnoticeable to the eye.
Clarity - Refers to the presence of inclusions in a diamond.
The clarity refers to the optical quality of a diamond. Diamonds are formed within earth and it is only natural fo them to
have certain imperfection within them, these are called inclusions. This is what makes each diamond unique.
Diamonds with the least imperfections are rare and have a higher value.
Cut - Refers to the angles and proportions of a diamond.
The cut is important to a diamond's overall appearance. It refers to how well diamond is cut which results in a diamond internal
light reflection and its brilliance. The shape of a diamond is closely connected to the above and while
being symmetrical round diamond reflects light the best.
