Certified Synthetic Diamonds Description
Whether it is natural diamond or lab grown diamond, the quality of diamond is determined by 4C's.

Cut:
quality
of
angles,
proportions,
faces
and
finishing
details
Color:
how

and

of
a

qualities
of

the

quality
of
lab
grown
diamonds.
For

the
ability
of
a
lab
diamond
to
reflect
light
to
the
eye
depends
largely
on
the
quality

the
cut,
but
also
on
the
color
and

For consumers, a professional diamond certificate can clearly show the detailed characteristics of the diamond. So that people can clearly know the quality of the diamonds they buy.

Certified Lab Grown Diamonds Introduction
Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The Lab Grown Diamonds are produced in the laboratory, usually in a few weeks. The chemical difference between the two is same.
So how do you distinguish between Lab Grown Diamonds and natural diamonds?
There is no obvious difference between the Lab Grown Diamonds and natural diamonds. Even professional gemologists need special equipment to identify them. By zooming in, professionals will be able to discern subtle contrasts in diamond inclusions grown and mined in the laboratory.
