Pumice vs. Perlite | 10 Differences Compared! | Bonsai Alchemist
The only two grades that pumice and perlite have in common are coarse and fine. Pumice also has regular and very fine sizes, which can be helpful in many applications. Perlite has super coarse and medium, which is why you'll find large and small pebbles. For the grades, it all depends on what you're looking for.

What Is Perlite? | Sciencing
Perlite is a volcanic rock mined in the United States, as well as other countries like China, Greece, and Italy. The volcanic glass, or perlite, is formed when lava (molten rock) spews out of a volcano, and cools in a rapid manner. Because of rapid cooling, water is trapped within the rock, and the lava forms into a glass-like structure.
