wow, thanks for the replies, its quite a rare/high standard (not sure of the correct term) diamond, so thats why its so expensive, we could get another diamond and bring the price down, the diamond would look the same to you and me, only a specialist could tell its quality.
I can see why it might look masculine from the photo, it didn't in real life, my worry is it doesn't look wow and like a typical engagement ring but then i didn't want anything too bling bling, its practical won't catch it, tried it with a plain wedding band - fitted well together.
I shall go and visit it again, you would think after 10 years i'd know what i want.
