When cut well, especially with a high crown, tourmaline can sparkle nicely, but it is a lower RI stone. It’s usually acquired more for the rainbow of color it comes in vs it’s ability to show fire and brilliance, The only high RI stone I can think of that comes in a teal color is blue zircon. and it’s affordable.
