Exactly right GuitarC, the obsidian hardness being 5.5 will make it suseptable to scratching/wearing against the steel strings which would be hardness 6.5 comparatively.
Although playing with plastic/lexan, musicians aren't suprised to see wear on those, but with stone picks, the finish could be damaged by use on steel strings if hardness is not taken into account, which is not expected to happen on a more expensive stone pick. Agates, jaspers etc in the quartz family carry just a little bit higher hardness range at 7.0 virtually eliminating any chance of wear marks from use during play.
