Which Diamond Is The Pair Of Darya-I-Noor Pink Diamond, Noor Al Ain Or Koh-I-Noor?

  During the reign of the next shah, Nasser-ed-Din, the Darya-i-noor was mounted in an elaborate frame surmounted by the emblem of the Imperial Government of Iran, and set with 457 diamonds and four rubies. It is still mounted in that same frame today.
