“Hidden within the carbon lattice that delivers the brilliance of a diamond’s sparkle lie insights into the history of our planet.”

“Diamonds are both dazzling gemstones and scientific time capsules. From the precise atomic arrangement of carbon that gives diamonds their brilliance to the microscopic inclusions locked within, each stone carries a wealth of information about the intense conditions deep beneath Earth’s surface. These ancient crystals are geological messengers, preserving a record of the high pressures, extreme temperatures, and elemental environments in which they formed billions of years ago.”

What are Inclusions in Diamonds?

”Diamonds are composed almost entirely of carbon atoms arranged in an exceptionally strong crystal structure. However, the inclusions found inside diamonds are not carbon. Instead, they are tiny remnants of other minerals, elements, or fluids that became trapped within the diamond as it formed deep inside the Earth.”

“These inclusions act as microscopic time capsules. Locked in place as the diamond crystallized, they preserve evidence of the extreme temperatures, pressures, and geological environments present billions of years ago. By studying inclusions, scientists can analyze materials that would otherwise be inaccessible—offering rare insight into Earth’s deep interior and the ancient conditions under which natural diamonds formed.”

“Ahead, explore how natural diamonds come into being, and discover what their inclusions and carbon isotopes can tell us about the planet’s deep history, the formation of the continents, and the dynamic processes still shaping Earth today.”

“Beyond their great beauty, diamonds are treasured by scientists for all of the things we can’t see.”
