Koh-i-noor

The Queen also faced sensitivities over what she wore at the Coronation, with a diplomatic decision not to use a crown containing the Koh-i-Noor diamond, which has had rival international claims to ownership.

As a boy, Duleep Singh had been exiled to England from India after his kingdom was annexed by the British in 1849, with the priceless Koh-i-Noor diamond handed to them under the terms of a punitive treaty.

Two years later, he expanded on the journal article with “The Pencil: A History of Design and Circumstance,” a 448-page tour through its invention and evolution — with brands like Faber-Castell, Dixon Ticonderoga and Koh-I-Noor among them — that included a chapter about the pencil-making business of Henry David Thoreau’s family in Concord, Mass.

This includes the controversial koh-i-noor diamond, whose ownership is disputed and which was not included in the Coronation.

That crown contains the famous Koh-i-noor diamond that India, Pakistan and Iran all claim.
