The way to grade a diamond is through its cut,
colour, clarity & carat, which is
what we called 4C.
In this 4C, the most important is the cut of a
diamond,
because
a good cut can let a diamond shine
out the best of its light.
Besides, diamond represents "Pure Love", which best
use for wedding ring,
because it had the meaning of
"Unbreakable Love", and the hint that she or he
is
your only true love until the end.
