Before you start diamond shopping, it's important that you have an understanding
of what you're buying.
This guide simplifies the four Cs of diamonds — cut, colour, clarity, and carat
weight, so you can select your diamond based on the same criteria gemologists use
to grade them.
After reading through this guide, you'll be ready to choose the diamond that's right
for you.

It's fairly common to confuse a diamond's cut with its shape. The cut describes
a diamond's light performance, dimensions and finish. Shape refers to the overall
outline of the diamond when viewed from the top. Round is far and away the most
popular diamond shape. In the other shapes known as fancies the most popular are
the square cuts, specially princess.

The cut of a diamond has the most effect on its sparkle, or brilliance. Even if
the diamond has perfect colour and clarity, a poor cut can make a diamond look dull.

Colourless diamonds are very rare and therefore more highly valued. Diamond colours
are graded from D to Z, being D totally colourless. Colour traces are noticeable
from I to Z, and this will become more apparent as we get closer to Z.
To choose a diamond with no colour noticeable to the unaided eye Platinum Diamonds
recommends to purchase a diamond graded as H colour or better.

Flawless diamonds are very rare and therefore more highly valued. Over 99% of diamonds
have flaws, also known as inclusions. Clarity is graded based on the number, location,
size, and type of the inclusions found in a diamond.

The weight of a diamond is measured in carats. Many people believe carat refers
to size, however it refers to weight. A 1 carat diamond can vary in size depending
on the cut of the diamond. Since larger diamonds are more rare than smaller diamonds,
diamond value tends to rise exponentially with carat weight.
1 carat = 0.2 grams

Make sure the diamond you purchase is accompanied by a full certificate. A grading
report documents
the specifications of a diamond like the four Cs, and it is also proof that it has
undegone a professional
examination. |
