Hi, Gaspare. It's good to hear from you. You have to be critcal; that's good.
If I've understand you correct���.
-The swastika is not a bit tilt, the horizontal and vertical axis are correct in relation to the front border. The twists aside are mirrored to eachother; left big twist goes twistup, right the big twist goes down. If you look frontal it looks a-symetrical (Celtic).

-Do you mean that the swastika should be in the center of a square instead of a rectangle front like this ring has ( good point!)?.. �I�ve seen that geometric art d�co rings have this. This twisted style I don�t know because I have never seen rings like this for comparison.

The enamel is deep; there is a deep chip in the centre of the swastika, no traces of fracture .
As you see, the wearer of the ring has handled it rather rough ; but the enamel didn�t break out to the bottem.

Gaspare, I hope that I have given you the info you asked for.
Thanks.
