In total, there are thousands of loose diamonds on display in the treasury. Many of these diamonds were brought from India by Nader Shah. It is assumed that these diamonds were mined during the Mughol dynasty in India. Of the thousands of diamonds, only three have a verifiable history: the Darya-e Noor ("Sea of Light"), the Noor-ol-Ain which in now incorporated in a tiara, and the Taj Mah diamond which is shown here on the lower left. It weighs 115 cts.
The other three loose diamonds shown here are 72.5 cts., 54.5 cts., 47.5 cts., and 54.35 cts. The one on the top left was probably cut from an even larger diamond.
