18k Gold Mother of Pearl Clover charm pendant, 14k gold chain

Real 18k gold pendant adorned with Mother of Pearl facing, pendant is stamped AU750. Chain is made of 14k gold 16" length also stamped, not counter fit. I do not misrepresent authentic items. If they are gold filled I state that in the title and the listing description.
Au is the symbol for gold on the periodic table, and 750 means the jewelry is 18 karat gold. So this stamp is just another way of indicating that the jewelry is 18K gold
