Aoi Kotsuhiroi / Malu Berbers / RoughDiamonds (Maya Bjørnsten)

Crystals, silk thread and lacquer make for a dark and stunning combination. Rings by France's Aoi Kotsuhiroi (don't miss the human hair necklaces!).

For a lighter take on raw crystal rings, see Dutch jeweller Malu Berbers. She also has a great, albeit ring-free, series in white PVC and cotton thread.

Bonus link: RoughDiamonds.dk delivers on its name. Danish designer Maya Bjørnsten does gorgeous work with unpolished gems, keeping things simple and organic.
