Kohinoor diamond's history: How the precious stone came into Queen Elizabeth's possession

With passing away of Queen Elizabeth II, United Kingdom's longest reigning monarch, focus has once again shifted to diamond, originally weighing 186 carats-- Koh-i-Noor. With King Charles III succeeding  throne, now 105-carat gem, which is steeped in history, will go to his wife Duchess of Cornwall Camilla, who has now become Queen consort. But, how did jewel come into possession of royal family? 

How did Kohinoor come to possession of royal family?

Though little is known about where and how Koh-i-Noor came from, it first found its mention in texts about Mughal emperor Shah Jahan. Shah Jahan h sought a jewel-studded throne, which took over 7 years to be built. Atop two pillars of this bejewelled structure were two peacocks- one with  Timur Ruby and or with  Koh-i-Noor diamond.

While Mughals continued ir supremacy over India, thriving with jewels of all sorts, it caught attention of many, including Persian ruler Ner Shah who inved Delhi in 1739. After invasion, he took along with him,  peacock throne as part of his treasury, but removed Timur Ruby and Koh-i-Noor diamond to wear on an armband. 

Koh-i-Noor remained away, in Afghanistan for 70 years, and passed from one ruler to anor before finally making its way back to India-- in hands of Sikh ruler Ranjit Singh in 1813. After Ranjit Singh’s death in 1839, Punjabi throne passed between four different rulers over four years, and last in line was a 10-year-old boy Duleep Singh. Imprisoning Duleep,  Britishers forced him to sign a legal document amending Treaty of Lahore, that required him to give away his claim to sovereignty, and Koh-i-Noor. diamond n became a special possession of Queen Victoria.
