From my grandmother's estate, looks like it's a promotional item of some sort. Original tag says Made in R.O.C. (Republic of China) of jade and coral. It as a nice weight and look it but it is clearly a costume piece. Can be converted to a pendant and put on a chain. Please note that the wording on the tag is indicative of it's age and is shown only for authentication purposes. No offense is intended or implied....thank you.
