Any gold jewelry item that the seller says is made of any of these labels is NOT SOLID GOLD.
GF or gf
GEP or gep
GP or gp
EP or ep
There may even be other misleading terms used to imply that the item is solid 10K or 14K or 18K solid gold. Always ask the seller if the item is solid gold and check their feedback. Ask if they accept returns if you're not happy. Look for the "Paypal buyer protection" on the right hand side of every listing. If it's not there, be wary.
Buy from sellers Like me (: with high feedback numbers and a good refund policy in place.
