good day! So after long holidays and been away I am back and have lot's to do ... I am doing now 14 ct stud earrings from yellow gold with rough diamonds. I have found solder 14 ct solder wich is ok... but seems cooksons do not have 14 ct studs in stock till June!!!! my Q is if I use 18ct studs would they not affect 14 ct marking? is it logical to mix metal that way ... ofc I understand that studs and back will be of better quality but if they will be for design as a piece...? This will be my 1st item ever I will do for sale ( if I am lucky ofc and someone buys it) so I do not want to mess up on it... also maybe I would be better off to learn patience and wait till June? ..I am impatient by nature....:-( or any other places to get 14 ct studs with backs. Many thanks.
