Understanding How Diamonds Are Formed

Have you ever stopped to think about how the sparkling diamonds in your engagement ring, tennis bracelet, or drop earrings came to be? The process by which diamonds take form is fascinating and begins nearly 100 miles beneath the Earth's crust.

Warm temperatures and high pressure at these great depths create the perfect environment for crystals to take shape. Once diamond crystallization has taken place, the stones are elevated to the surface of the Earth through a volcanic eruption. This process, known as a kimberlite eruption, has not occurred in recent times and is in fact quite rare even when examining the Earth's broader geological past.

The diamonds that you see from your coin and gold dealer are both old and rare. Although no one can know for certain how old diamonds may be, people do know that these stones are to be treasured.
