wholesale faux turquoise jewelry The standard of 4C diamonds is CARAT Carat, Clarity clarity, color color, and CUT cut. It is the international standard. The GIA of the American Jewelry Academy is the earliest 4C grading institution. The 4C marked by the Blue Nile page is assured, because each diamond of the Blue Nile family has an authoritative GIA certification certificate. The 4C displayed on the page is authorized by authority and will not have deviations.
