Grammatite

Named after the Tremola Valley in Switzerland, where it was first identified. A calcium-magnesium mineral of the amphibole group, most commonly found within metamorphosed limestone—marble.

Mineralogically, tremolite can occur as a form of asbestos. But the material used as a gemstone is the dense, massive variety, structurally distinct from the fibrous form. Same mineral name, entirely different character depending on crystal habit.

Little known as a gemstone, yet significant as an index mineral. Its presence reveals what temperature and pressure shaped the surrounding rock. Inconspicuous, but far from silent.

Not for the person who pushes through. For the one who works by permeation — slow, even, persistent contact until the other side comes round on its own. He chooses agreement over persuasion. Looks delicate from a distance. Reaches further than force ever could.
