I''m recently engaged and have received a family ring that is set in yellow gold. My fiance knew that I wanted a platinum setting but wanted to present the ring to me in its original form. So now we will be having the ring reset in platinum. I am wondering where I should begin and what I can expect the cost to be? It is a small three-stone setting...total carat weight is 0.82, all round diamonds, center one being 0.3 carats. Any advice will be appreciated. Thanks!!
