Good old gold is offering the .79ct diamond with a platinum solitare ring for $3500 the setting is $900

but I see that Brian gavin has a .84ct and sells a platinum solitare ring for about $575


whats the difference between both vendors? i guess their polices in upgrading

what do you guys think would be the best diamond>?
i want a great diamond i dont mind buying the setting separate if i have to. But i would perfer buying everthing together.

What do you guys think of brian gavin?

sorry for my rambling. im just trying to buy my love the best i can afford
