Large Chinese jadeite pendant circle characters lucky good fortune

Large Asian jadeite circle pendant with Chinese lucky characters for good fortune. I believe this is jadeite, but I'm not entirely sure it's not a light colored jade or nephrite. Features a center carved flower. It's marked 375 which means the metal is 9K gold. Has a bit of tarnish but should polish up beautifully. It's about 2 inches in diameter. Beautiful piece! Sold without chain.
