I carry around a relatively small moon-shaped amethyst pretty much everywhere I go! Its kinda become my good luck charm and its super special to me but I've always been super skeptical of its actual origins bcs it was relatively cheap for an amethyst, so i might actually be carrying around plastic but its an amethyst to me XD
Also there arent really any reputable places that sell crystals here in kosovo so you kinda have to go with yr gut most of the time
