The Mughals were known for their love of jewelry and gemstones, and rubies were a favorite among their rulers.
The Mughal Empire
The Mughal Empire was a period of great cultural and artistic flourishing in India. The Mughals were known for their exquisite jewelry, which often featured rubies set in gold and other precious metals. The rubies used in Mughal jewelry were sourced from various parts of India, including the famous mines of Ratnapura in Sri Lanka.

The Origins of Indian Rubies
Geological Formation
Indian rubies are formed in metamorphic rocks, typically in the presence of aluminum-rich minerals such as corundum. The formation process involves intense heat and pressure, which cause the aluminum to crystallize into a red form known as ruby.
Mining Techniques
The mining of Indian rubies involves various techniques, including open-pit mining and underground mining. Open-pit mining is often used for larger deposits, while underground mining is used for smaller, more concentrated deposits. The mining process requires careful extraction to ensure the integrity of the gemstones.
Processing and Cutting
After mining, the rubies are processed and cut to enhance their beauty and value. This process involves several steps, including sorting, cleaning, and cutting. The cutting process is crucial, as it determines the final shape and brilliance of the ruby.
