I don`t know anyone that has this type of earrings I only have some design ideas. So if someone got some measures so I can make a base so I attach my sculpted design to it will be very helpful. I have searched in some local shops they are not so popular in my country! My guess it is they are 5 mm diameter / 11 mm long ? Or like flared to 6 mm / mid 5 mm / long 11 mm ? Thx.
