String Crystals, Tourmaline (black) AA (stab.), appr. 10 x 06mm
Selected crystals of black tourmaline (Schorl) were drilled lengthwise and carefully threaded for this strand. The individual crystals are about 1cm long and have a diameter of about 6mm. The typical groove surface can be clearly seen.
