One Loop in rose quartz

The same puzzle as our wooden piece of the same name, with every wooden part cut from rose quartz instead. Each part is shaped from one piece of stone, polished by hand, and every edge and corner is rounded so the stone does not chip where the cord pulls across it.

Rose quartz is quartz in a soft, milky pink. At 7 on the hardness scale it is harder than a steel knife, so everyday handling does not scratch it.

The cord is the same as on the wooden piece, so the solution is the same. We can cut it in rose quartz, amethyst, nephrite jade, lapis lazuli, black onyx, red jasper, tiger’s eye or smoky quartz.
