Hello,
Sorry to hear that, in terms of the pendant, this is the current model, what happens is there is always a slight variation on the pendants because these designs are over 3-4 years old and they're all handmade so sometimes manufacturer will slightly change design we just don't update the picture because it's only a slight change. The gap is on both versions but yes it does appear to be a little more flat, the back is the same on both though. We can give you a refund if you would like or maybe a discounted price for the inconvenience. Please let us know and sorry for the inconvenience.
