Tras 28 días (7 días por step) y 3 días con GemFoam, conseguí que mis piedras brillasen y estuviesen lisas. La verdad es que no obtuve estos resultados a la primera, es un proceso lento, pero gracias a informarme y a prueba-fallo, conseguí que quedasen bien. Y el GemFoam posiblemente ha sido el causante del brillo.

Very good grit, and the foam actually works for the fifth step. I was pleasantly surprised.
