Ruby Ring

I Have A Ring With A 3x5mm Ruby Set In 14k Yellow Gold. I Don't Like The Style Of The Band, And I Don't Wear Yellow Gold. I'm Thinking About Getting It Reset Into A White Gold Band, And Maybe Adding Two Tiny Diamonds From A Pair Of Earrings That I Don't Wear Very Often. I Think It Would Make A Much Nicer Ring, But What Would The Price Range For This Be?
