Natural diamonds are more than just beautiful—they’re geological marvels with stories billions of years in the making. At M. Geller Diamonds, we believe understanding where a diamond comes from adds meaning and value to the way you sell it.
Here’s a deep dive into what makes natural diamonds so special—and how we ensure the ones we source are ethical, expertly vetted, and worth the wait.
Formed Under Pressure: The Science of Natural Diamonds
Natural diamonds are formed deep within the Earth’s mantle—90 to 150 miles below the surface—under extreme heat and pressure. Over millions (and sometimes billions) of years, carbon atoms are compressed into a crystalline structure that results in unmatched hardness and brilliance.
The result? The iconic octahedral diamond crystal, built with equal strength in all directions.
How Diamonds Reach the Surface
Once formed, diamonds don’t stay buried forever. They’re brought closer to the Earth’s surface through powerful volcanic activity, traveling via kimberlite and lamproite pipes. These rare geologic events help bring nature’s most coveted stone within reach.
The History of Desire
Humans have admired natural diamonds for centuries. First referenced in ancient Sanskrit texts from the 4th century BC India, diamonds were symbols of status and strength. India remained the dominant diamond source for centuries until new deposits were discovered in Brazil, South Africa, Russia, Canada, and Australia. In the late 1800s, modern diamond mining began with significant finds in South Africa—and global demand has steadily grown since.
Mining Methods That Move Mountains
To recover natural diamonds, two primary methods are implemented:
Ethics in the Modern Market
While the diamond itself is timeless, how we source it matters the most. That’s why M. Geller is proud to be a longtime member of the Responsible Jewelry Council. We actively support initiatives like the Kimberley Process to ensure our diamonds are conflict-free and ethically sourced.
Why This Matters for Retailers
Educated clients are asking more questions—and they care about transparency. At M. Geller, we empower you with answers backed by a supply chain that prioritizes integrity.
