Certain gemstones have traditionally been associated with particular wedding anniversaries. Emily Post, an American socialite, was the first author to publish a list of etiquette concerning anniversary gemstones back in 1922. Since this time, the list has expanded and been updated to include:
|13th||Citrine or Moonstone||70th||Platinum|
Rich and rare were the gems she wore,
And a bright gold ring on her hand she bore.
~ Thomas Moore
