Almost too classy to give as a gift:
This bottle stopper is topped with a crystal of black tourmaline.
Size of the crystal about 4 cm, total length of the wine stopper 10.5 cm.
Black Tourmaline (black) has always been used as a protective stone. It conveys neutrality and serenity. The more you rest in yourself, the better you can deal with external influences and disturbances.
