You mean like a ring in and of itself, so that you put your finger through? I’ve tried that actually, but to make it comfortable you need to make the struts quite thin and the gaps tiny, and since the whole shape is one single line, it’s going to be quite prone to bending and misaligning when made from silver or gold.

It’s actually a problem with tables like this, they are quite wobbly unless welded from thick square steel tubing, and even then they’re not really solid.

It’s possible to make the ring both wearable and stiff in one orientation though.
