All repairs or alterations must be completed by GURHAN or the lifetime warranty will be voided.
In reference to rings specifically, some people feel that their jeweler is “good” and they should be able to make the adjustment. Typically sizing can be done by any qualified jeweler on gold which contains an alloy and is not pure, such as 18K. Good jewelers are extremely skilled in such a metal. 24K Gold is a different story altogether.
The more important issue here is that as Gurhan is one of the original pioneers of using 24K Gold in jewelry, something everyone said originally couldn’t be done because the metal was considered too soft. He is among a very elite few whom understand the metal and therefore the techniques needed to master it. If a person does not personally know 24K Gold intimately along with knowing and understanding Gurhan’s personal techniques, they will cause irreparable damage to the ring.
