What Are Natural Diamonds?

Natural diamonds are formed deep within the Earth's mantle under extreme heat and pressure over billions of years. Through volcanic activity, these diamonds travel closer to the Earth's surface, where they are eventually discovered and mined.

Every natural diamond represents a unique piece of Earth's history, making it one of nature's most extraordinary creations.
