thank you. Is it stamped on clasp as 10k? Usually gold is stamped. Also if its plated, it is stamped as 10k gp or hge and if its filled, its stamped as 10k gf or 1/20 or 1/10 10k depending on ratio of gold used. So if you can look into the stamps or markings, it will be really helpful... watching and bidding on this...:)
