setting/basket

[BEDAZZLED]

I have an extra setting with a V head for a round stone.

Can I put a square sapphire in this setting w/o changing the basket/head?

If the stone fits, maybe it will work. Is it really a square stone with 90 degree corners or a cut corner type, like an emerald cut. That might be a better fit.

Looks like a princess-cut with no facets---square step cut.

I guess the best thing to do is to take it to a jeweler.
