The yellow/blue cube in f102v2

[EllieV]

Terms like that were usually applied to Lapis Lazuli (and sometimes to Sodalite). I'm not sure why there are two with almost the same name, but it's possible they used different terms for the same stone, based on the proportions of minerals/colors.

Lapis is the Latin word for stone in general. However, in the old times some things were called lapis that were not stones - for example in Materia medica Lapis judaicus is actually a fossil. Also Lapis pilosophorum (philosopher's stone) can be a substance that is not necessary a stone.
