If you are interested in jewelry by Bounkit this is a great time to indulge as they are running a 30% off Labour Day sale (and if you miss it, you can get 15% off as a new subscriber.

This piece is available either with black onyx or horn as the base and I believe the stones used are crystals, though they may be semi-precious (they say amethyst and blue quartz). There are matching earrings.

Pre discount, this sells for USD$430.
