A heart it was, bound in with diamonds,

And threw it towards thy land.

(Part 2, Act III, Sc. 2.)

Horoscope of Shakespeare

King Henry: “My crown is in my heart not on my head:

Not decked with diamonds and Indian stones

Nor to be seen: my crown is called content

A crown it is that seldom kings enjoy.

(Part 3, Act III, Sc. 1.)
