Amantes in nephrite jade

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

Nephrite jade is a deep spinach green. Its fibres lock together, which makes it one of the toughest stones there is: it resists chipping better than quartz.

It is a fine-grained or fibrous stone. Its tiny grains lock together and stop a crack from running, so a diamond tool follows our CAD file cleanly and the finished piece resists chipping.

The cord is the same as on the wooden piece, so the solution is the same. The piece comes in nine stones and their natural colours: pick one above and the price follows it.
