IKS is the maker’s mark for the Sandeep Diamond Corporation, based in New York, NY. They use this mark for jewelry containing diamonds, most notably bracelets, rings, earrings, necklaces and pendants. Of all the marks that could be on your ring, the one that tells the karat weight is probably the most important. Karat weight can be written in a variety of different ways, as there is no standard and each manufacturer has its preferred method. You can commonly see it written as 10k or .417 for 10 karat gold (either white or yellow). 14 karat gold may be written as 14k or .585 (again, either white or yellow). Carat weights are the second most common stamp in a ring and indicate the weight of the diamond or jewel.
Diamonds may be in shorter supply in coming months, as rebels have taken over the diamond-rich region of Bria, in the Central African Republic (CAR). The rebel coalition has announced its intentions to overthrow the government, headed by President Francois Bozize, who they insist has not complied with the terms of a 2007 peace treaty. The four towns that the rebels now control link the CAR to other areas such as Sudan, Cameroon and Chad.
