its only 18k gold plated, not full gold This could be incorrect. If the ring has 18K/PLAT then the ring is 18K gold with some platinum. Probably to hold the diamond.

The crown is a standard mark, meaning the gold conforms to one of the gold standards. K stands for carat. It is a unit for purity of gold. 22K indicates that the ring is 91.7% gold and 8.3% other metals.

Better to lose a 9k gold ring than a 18k one ! 18k is purer gold than 9k.
