＊About GF, 1/10...
GP means Gold-Plated while GF means Gold-Filled.
GF (Gold-Filled) is made with solid gold, from 50 to 150 mills of "solid" gold mixed with other alloys of metals these metals vary among copper, rodhium (a member of the platinium family). The process is different since its done through "heat" which gives the gold the property of sticking longer giving it lifetime quality in contrary of GP(Gold-Plated) which fades fast.
1/10 means that the thickness (ratio) of Gold is 1/10 of the whole.
