Magnesite008

Crazed white magnesite beads, dyed blue-green magnesite and blue dyed magnesite. The crazing on the large flat and oval beads is particularly nice. My assumption is that the crazing is produced by heating and cooling in a bath of brown or black dye to produce the "matrix" or "spiderweb" lines.This material is often (but inaccurately) called "chalk turquoise."
