What it actually is
Chiastolite is Al₂SiO₅ before it is a story. The lattice is orthorhombic, Mohs 7–7.5, and the eye meets black, white.
The better pieces still come out of the ground in Spain, Australia. Graphite pushed aside as the crystal grew draws a dark cross on the sawn face.
What the old tradition whispers
The parlour tradition ties Chiastolite to earth and to the root centre. The old site stood it near: Scorpio, Capricorn.
How not to turn it to ash
A hard stone survives a daily ring, yet two diamonds in one box will scratch each other. Warm water and a soft cloth are enough.
