(Bloomberg) -- Angola will conduct its first diamond auction in January as part of the southwest African country’s plan to open its economy to foreign investors, state-owned diamond-trading company Sodiam said.

Seven gemstones from the Lulo mine, located in the northeast, will come under the hammer, Sodiam said in an emailed statement Monday. They include a 114-carat stone and a pink, 46-carat gem. Several international buyers will be invited to the sale, which will be held at the company’s headquarters in the capital, Luanda. Sodiam didn’t give a date for the auction.
