Alrosa unearths 191-carat diamond at Botuobinskaya pipe

According to Mining News Pro - Even though Alrosa experts are still conducting mineralogical analyses on the stone, preliminary results suggest that the diamond is about 2 billion years old.

“This is a true sign to find such a large and high-quality diamond just around the end of the year,” Evgeny Agureev, the company’s deputy CEO, said in a media statement. “Nature has already endowed us in 2019. For example, a heart-shaped diamond was mined at the Udachnaya pipe just before Valentine’s Day.”

Discovered in 1994, the Botoubinskaya pipe, together with the Nyurbinskaya pipe, is operated by Alrosa’s Nyurba Mining and Processing Division. The unit, however, was established back in 2000 and mining at the deposit began in 2015.
