Answer:
If Teresa’s daughter is my daughter’s mother, who am I to Teresa?
Covered in stone and sun. It's home to many but also none. What is it?
I am mother and father, but never birth or nurse. I'm rarely still, but I never wander.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
The more you take, the more you leave behind.
I’m grown from darkness but shine with a pale light. Very round I am and always a lady's delight.
