It looks pretty much exactly as it does in the picture, absolutely gorgeous.  It shipped quickly and was packaged well.  I especially love the Peora ring box.

Some details: the entire square section that houses the cubic and sapphire centerpiece is exactly 9 mm across, so it is a little on the big side.  The sapphire itself is only 5 mm.  The band is 2 mm wide, so it looks a little small compared to the centerpiece.  And, the centerpiece is raised about 4 mm from the band to the base of the centerpiece, if any of this will bother you, I suggest looking elsewhere.  It is also stamped 925 for the silver.

Keep in mind that it looks silly stacked with a band, as the band is forced to sit a few mm off from the band on this ring.

The setting on the sapphire is firm, and the CZ set into the band/sides all seem to be set pretty solidly as well.  Overall, this is a good purchase for the price.

Edit:  10 months later, and it's still a lovely ring.  All the stones are still set solidly in place.
