I''ve been shopping around and doing the research thing for my fiance-to-be, and I was wondering if the ring I''m interesting in purchasing is too pricey. It is a cushion cwt., IVS certified, .78 ct, HS1...at the price of $3600... $3800. with tax and all. I was originally going for a princess cut, but not sure if I should pick the cushion over the princess cut (same cwt). This of course is not my ring to wear, but i want the very best for her; even though she has mentioned that diamond size really don''t matter. She hates it when i go all out and pay expensive things for her.
