To meet today’s demands you need more than the 4Cs. Consumers will benefit from the third party independence
and support of the GCAL Five Star Diamond Certificate,
which bundles all security, technical and sales information into one diamond grading certificate.
The Ideal Cut diamond is based on “triple ideal” parameters where the diamond is
“excellent” in all three ratings: (1) proportion- girdle thickness, culet size, table %, total depth %, crown angle, pavilion angle;
(2) finish- polish and symmetry; and (3) direct light assessment - optical brilliance
and optical symmetry.
GCAL offers GemFactsSM, the next generation in diamond certificates and an electronic
record of a diamond.
The SourceVeritasSM

is providing a revolutionary new step to assist your customers and raise consumer
confidence.
