The origin of colour in fancy coloured in diamonds is of paramount importance to its value.

A diamond will either be of natural colour origin as created by nature, or it has been treated and enhanced.

DCLA has the experts with technical ability and equipment necessary to authenticate fancy coloured diamonds as natural.
