I want to identify whether a ring is platinum and its composition. Where should Guilin go for identification? I heard that Qili Store has any jewelry appraisal, but 1 14 can't find it.
If it's platinum! The ring will be engraved with the code PT990 or PT950. PT is platinum! 990 and 950 are the platinum content of jewelry! That is purity! 990 contains 99% and 950 contains 95% platinum.
If you really can't, go to the gold shop and let the sales staff in the store help you! No money! I sell jewelry in Guilin!
