mikeswift is right, 1 - 1.5 is huge on tiny girls like my wife is tiny and hers looks pretty damn big and its just over a ct, and i spent just over 5k and if i could do it over i would never have picked white gold ring, its nice and all at first but even if you have to get it diped a couple times in a lifetime its scary caues leaving your wring with the jewelr is scary shit, for all u know u could have ur stone switched, it happens all the time, ourt jewelr was a freind thankfully and no worrys there
but buy platinum bro no white gold biggest mistake i made, and check the clarity urself, u will be abkle to tell after looking at a few wrings the huge difference in clarity and the inclusions and such, i was a pro by the time we finaly picked out my wifes,lol, yes she went with me, made sure she got what she wanted,lol, its a great diamond and a nice looking band but never never never buy white gold like we did!
