eternity bands

I LOVE this ring that I found on bluenile.com. I was wondering what you guys think I could get it for (it's $1600 for my size on bluenile).

Here's the description:
Platinum Channel-Set Diamond Eternity Band (1 ct. tw.)
Round, brilliant diamonds encircle this ring, channel set in platinum.

Since I'm a size 4, it would be a total of .90 ct.
