Etymology

 * Ruby refers to the red jewel. The jewel ruby derives from Latin rubeus "reddish". It's possible she is named after Frodo's grandmother, also named Ruby.
 * The name Diamond is derived from Late Latin diamas, from Latin adamas, which is of Greek origin meaning "invincible, untamed". Diamond refers to the precious gem that is rare to come by. It is also the name of Rosie's best friend, Diamond Took, which is one of the reasons why Ruby Diamond is named after Diamond of Long-cleeve.
