can i assume if i can see 8 arrows with unaided eyes ...

it''s a decent cut stone? it may not be ideal, but at least well cut?

in my unexpert opinion, it would indicate that it had great symmetry if you could see the arrows in a star shape. maybe not that it was the creme de la creme but if you could see THE pattern, i'd tend to think it was probably a pretty nice stone.
