My fiance gave me a gorgeous vintage engament ring that belonged to his grandmother. The stone is a .85 ct mine cut diamond (SI1, G). I love the ring. the only problem is that the stone has a very large culet, so you can see right through to the bottom. I''m afraid it makes it look a little weird. I''m wondering if it would be possible/advisable to have the stone recut to make the culet smaller?
