THE 4 C'S
Because diamonds are so valuable, it’s essential
to have a universal grading system for comparing
their quality. In the 1940s and ’50s, the
Gemological Institute of America (GIA) developed
the 4C's and the GIA International Diamond
Grading System™ to objectively compare and
evaluate diamonds. This is why we have chosen to
explain the 4C's according to the specifications
as provided by the GIA.
You may already know the 4 C's are Carat
(Weight), Colour, Clarity and Cut. What we've
tried to do is break down each of those
components and offer up information to satisfy
the novice all the way to the expert.
