It's a square.  It's a sprial. It's both at once.

Because of Squyral's square shape, it is very thin between fingers and it has the effect of a Euro Shank to keep the top of the ring upright. The stainless balls are trapped in tension as the ring loops around twice. A fun ring.

The ring shown is a size 6.5 and is around 2.5mm wide at the bottom and has a polished finish.  There's no room for engraving in this ring.
