Violet Stones

Chambers's Encyclopaedia, Volume 10: Swastika to Zyrianovsk and Index, p. 487

Violet Stones, stones found upon certain mountains, as on the Brocken and the Riesengebirge, which, in consequence of being covered with Violet Moss, emit a smell like that of violets. Violet Moss (Chroolepus Iolithus) consists of simple articulated threads, and spreads over the stones in the form of a delicate incrustation.
