Prasiolite

Any comments on the use of the term “Prasiolite” - supposedly a heat
treated amethyst (quartz) - would be useful.

I recently aquired some that I would describe as lemon yellow rather
than green and feel I should sell finished pieces as citrine rather
than Prasiolite.

Also capitalization. Should it be a P or a p?

Thank you, Oh Wise and Wonderful people!
