The criteria used by the gemology labratories
performing diamond certification are the 4 C's: cut,
colour, carat and clarity - Read about the 4C's via
the links below.
Certification is a safeguard for the consumer,
however, opinion on an individual diamond can vary from
laboratory to laboratory and certification will increase
the cost of a diamond as there is a laboratory charge
to have a diamond certified.

diamonds, please don't hesitate to contact us directly:
