You draw me, you hard-hearted adamant!
– William Shakespeare
A Midsummer Night’s Dream, Act 2, Scene 1. Adamant was a lengendary rock which was no hard that it was said to be unbreakable and impenetrable. In Shakespeare’s day adament was also associated with lodestone, a naturally magnetized mineral. Helena, in metaphorically comparing Demetrius to adamant, is confessing that she is draw to him like metal to a magnet.
