Gold and Diamond Mining
A U with an arrow through it on a diamond ring does not have a significant meaning. It is most likely an engraving or marking of some kind.
i thnk it meens 18 carot gold i dont knw the SP sorry
it means that your "diamond" ring is not actually a diamond, but a Moissanite ring! Moissanite is a alternative to diamonds. They're scientifically proven to have higher clarity than diamonds and the same scratch resistence. My engagement ring is moissanite and it's gorgeous!
Whatever marking you find on a ring marks the mounting, not the stone. The indicator 14d stamped in the metal may indicate a style, type or design.
Am led to believe it is zirconium
The marking CZ on a ring usually stands for "cubic zirconia," which is a popular diamond alternative used in jewelry. Cubic zirconia is a synthetic gemstone that closely resembles the look of a diamond but is less expensive.
