The only reference I found is one refering to aphrizite being the highest level of tourmaline and it was a jeweler likely using the term to differentiate his black tourmaline from other tourmaline to charge a higher price.
I looked up the etymology and it said this
aphrizite
A variety of tourmaline; from the foam element because of its appearance of bubbling when heated.Tourmaline is a mineral of various colors used as a gem.
Schorl comes from a German town called Zschorlau been in use since before 1400 AD
