“The first pair Opal and Amber are,Agate sings in B flat, the wolf avatar,A duet-solutio! - with Aquamarine.Mighty Emerald next, with the lovely Citrine.Number Eight is digestio, her stand is Jade fine.E major's the key of the Black Tourmaline,Sapphire sings in F major, and bright is her sheen.Then almost at once comes Diamond alone,Whose sign of the lion as Leo is known.Projectio! Time flows on, both present and past.Ruby red is the first and is also the last.”
