Shunka I think I agree. I lost a large stone in my wedding/engagement set. They are intertwined so I can't wear them until we replace the stone - in the meantime I'm wearing the Mystic fire topaz ring that Bob got me for Christmas. I absolutely love it - and he says it fits me - firey and colorfull!
But I can see the advantage of a stone that big - you'd notice right away if it went missing from your ring.
