Shasta, pop that one in the box and send it back - I can tell by the number of pictures and the amount of detail you tried to show that you're just not fabulously happy with it - explain to your SA what you don't like and you'll get another!
It's partly the veins and partly the resulting very-mottled look I think you're reacting to - they are not all as variegated and some people like the more variegated look - but it's one of those things a person probably would gravitate to in person.
Let us know what you decide. So sorry - I know you were very excited. You'll get to be very excited again though! Two excitements for the price of one!
