ahh an engagement ring, the hardest one to buy cause you cant ask them what they like :P

since my missus loves jewelery ive been to a few places. i found that goldmark was good, got her some decent stuff from there, and i think that bevels was a bit more pricey. best thing you can do is get a clear picture of what you want and then just look around at all the different shops, you might get a real bargain
