How Coloured Stones Are Formed
Coloured stones form under specific geological conditions, often over millions of years. The process begins deep within the Earth’s crust, where heat, pressure, and mineral content interact to create these stunning gemstones. Factors like temperature, pressure, and the presence of trace elements determine a stone's final color.
For instance, the presence of chromium gives emeralds their green hue, while iron and titanium contribute to the blue color of sapphires. Coloured stones are typically found in igneous, metamorphic, or sedimentary rocks, depending on their formation process. Once formed, they are brought closer to the Earth’s surface through tectonic activity and mined for extraction.
