The Royal Crown Jewels of the various nations are one of the most popular collections in the world. Did you know that long before Diamond Engagement Rings became a standard part of most marriages, coronation rings were given to Sovereigns, male or female, as a symbol of their “marriage” to the nation? For example, in the UK, the Coronation Ring is also known as the Wedding Ring of England. They usually contain Rubies or Sapphires with Diamonds.

In light of the recently claimed “largest” Rough Diamond in the world, twice as big as The Cullinan, I thought you may like to see a couple of the Polished Diamonds that came out of the Cullinan. I’ve also added a picture of the famous Koh I Noor Diamond:

  The Cullinan I, 530 carats appearing in the Royal Sceptre
