How far you have to dig down to find diamond?

Diamonds are typically found at depths of about 150 to 250 kilometers (93 to 155 miles) beneath the Earth's surface, within the mantle. However, they can also be brought closer to the surface through volcanic eruptions, forming kimberlite pipes. In practice, mining for diamonds often involves excavating much shallower, surface-level deposits that have been weathered and eroded from their original locations. Thus, while the geological source is deep, mining operations often occur at much shallower depths.
