India was termed the “jewel in the crown” because it was the most valuable of all of Great Britain’s colonies. Britain exploited India for its natural resources as well as its location. Britain literally milked India for the raw materials they could get and then sell at elevated prices.
Among these were Indian pepper, silk, cotton, porcelain, fine spices, tea, and coffee. India’s location was perfect too as it is in between Britain and China so it was perfect for the silk trade.
