The reddish to purple colored tourmaline is called rubellite. It’s a
natural stone. Is this what you’re thinking of?
Rubylite is a the name of a variety of Calla Lilly.
If there is a material called Rubylite then it’s vaguely fraudulent
use of the “Ruby” bit of it’s name would make me steer clear of it,
as it’s probably only a variety of manmade corundum!
