Iowaite

Q: What is Iowaite made of?

Iowaite has the chemical formula Mg₆Fe³⁺₂(OH)₁₆Cl₂·4H₂O, crystallises in the trigonal system and measures 1.5 – 2 (Mohs) on the Mohs scale. Iowaite is a hydrated magnesium-iron hydroxide chloride belonging to the hydrotalcite supergroup, with a layered double-hydroxide structure in which Cl⁻ and water occupy the interlayer. It forms as a low-temperature alteration of brucite and serpentine minerals in serpentinised ultramafic rocks and was first described from a drill core in Precambrian rocks of Sioux County, Iowa. Because it is very soft and readily oxidises to a brown ferric phase, iowaite is a specimen mineral rather than a lapidary material.

I. The Metaphysical Reading

How the stone has been held.

Iowaite is worked with as a soft-water stone of buffered speech, held when honesty needs to be said without corroding the room. Its pale green layers are said to remind the carrier that clarity can be gentle and still be true.
