By "violet", do you mean purple like Amethyst? Amethyst ranges in color from a very light lavander through deep purple. I have some earrings like these in Amethyst that is a medium to dark purple.
What gorgeous peridot beads. I've had some beads like that in the past and didn't have much luck designing with them, but that is a very pretty pair of earrings. Good luck with your listing!
