You will be ripped off. The listings state that silver is 95 i.e 99.9% silver but his jewelry is made of silver-zinc, silver-brass etc and coated with some other metal.
Gold is not 18kt gold, it is gold over brass! The seller never indicates such details on the product listings because he/she knows that you cannot prove!
I called him/her out on it but this hubris has ripped so many people off while getting high ratings from unsuspecting eyes.
Aliexpress will back him/her 100% because of the bogus ratings!
I warn you, GEORGE SMITH JEWELRY IS A CHINESE SCAM!
