A 131.5-ct. piece of white diamond rough—larger than the famed Koh-I-Noor—was recovered from a mining concession in Angola.
West Perth, Australia-based Lonrho Mining said it had recovered the stone from a bulk sample at its Lulo concession. It is the largest find since the company started prospecting there in 2008.
The company also found a 38.3 ct. piece of rough in the same sample.
The company didn’t specify color or clarity or how the stone would be sold, but said the rock was “gem quality.”
In a statement, managing director Miles Kennedy called the stone’s size “incredible” and said it indicated a kimberlite source was nearby.
The Lulo concession is a joint venture between Lonrho and Angola’s government-owned diamond company, Endiama. It is located in the country’s diamond-rich Lunda Norte province, some 750 kilometers from Angola’s capital city of Luanda.
