Hard stone ring purple

Ring in 925 silver and amethyst quartz hard stone.
Processing similar to the lunar surface covered with craters.
This process gives the ring a very seductive play of light and dark.
The shank is open on one side and sets the round and flat stone on the top.
Unusual design and great visual impact.
NOTE: using only natural stones they may differ slightly in color and shape from those in the photo.
Handmade in Italy.
