Answer:
Lovely and round, I shine with pale light, Grown in the darkness, a ladyβs delight.
I can be simple or I can be complex. I can be found in this riddle or in everyday life. I can be shapes or even colors.
Sometimes dark and sometimes bright I make my way among twinkling lights. Seas and oceans obey my call yet mountains I cannot move at all. My face is marred and gray But I'm majestic anyway
I work when I play and play when I work. What am I?
I have a straight back and sharp teeth to cut objects.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
