Iranian kings hadn’t attempted to preserve jewels and ornamental gems before Safavid dynasty. During this period some ambassadors were sent to neighboring countries to purchase and collect jewels and conserve them. After Afghans invasion, some of these jewels were sent to Afghanistan and India, but they were taken back and returned to Iran by brave endeavors of Nader Shah, one of the most powerful Iranian rulers of Persia from 1736 to 1747. He also sent many letters to Indian king to retrieve some of these jewels, but when he didn’t get any answers, he moved his army toward India and took some of these jewels back. During the Qajar era the jewels were collected and some parts of it were fixed on Kiani Crown, Naderi Throne and the gemmed globe and were kept in Golestan Palace. During the rule Reza Shah, the national jewelries first were moved to Marble Palace and then to Bank Melli Iran. The bank later became a museum and today is known as National Jewelry Museum in Tehran. Many Iranian jewels from the Safavid, Afshar, Qajar and Pahlavi periods have been exhibited in this museum. Some world-famous treasures including Daria-i-Noor Jem which means “Sea of light”, Jeghe Naderi, Crown of Farah Pahlavi, Kiani Crown, Sun Throne and Naderi Throne are just some parts of these jewels that are kept in National Jewelry Museum in Tehran.
