I hope you had a nice Easter .when I got these beads because I wanted to know what they are made off because they look like rock but sound a bit like stones do when u knock them together but the are not as heavy as you would think they are plain blackI have washed them in hot soapy water and looked at them with an eye glass and they are just plain black but if you put a light near them they are green and like a rose colour and a a white colour in parts do you know what they are please? My mum said perhaps some one made them . Here they are from Lulu
