In King Henry IV, Part I, Act 2, Scene 4, Prince Hal says to Francis:
“Wilt thou rob this leathern jerkin, crystal button, knott-pated, agate-ring, puke-stocking, caddis-garter, smooth tongue, Spanish-pouch,...”
Falstaff in Part 2, Act 1, Scene 2, of the same play complains to his page that he was never “manned with an agate till now.”
(These quotations all serve to show how popular the agate was as a ring stone in Shakespeare’s time.)
AMBER
Hamlet, in answer to a question, tells Polonius that the “satirical rogue” whose book he is reading says that old men’s eyes are “purging thick amber and plum-tree gum” (Act 2, Scene 2), a thought no doubt suggested by the ancient myth of the “weeping sisters.”
Petruchio asks his “Mistress Kate”:
“Will we return unto thy father’s house
... With amber bracelets, beads, and all this knavery?”
(“Taming of the Shrew,” Act 4, Sc. 3.)
