Collection: Koppa

Koppa are smaller, irregular cut, or non-rectangular stones. They can be Arato(course), Nakato(medium) and Shiage(fine) and the term refers strictly to size/shape. Many people like koppa because they are often more affordable than their full sized counterparts. A majority of what we sell are fine finishing stones and we will of course note otherwise.

All of our koppa are individually tested and graded so you can buy with confidence, no matter the price!
