The GTR that you are seeing is the manufacturers branding on the jewelry. 10K means that it is made out of 10 karat gold.
Best Answer: '10kp' would mean 10 karat gold plate (if it is '10kt' then it is 10 karat gold). GTR is most likely a manufacturers stamp as, generally, a ring only has the type of metal and the manufacturer stamped inside, nothing else.
