The miner has exported a parcel of 3,341 carats to diamond trading hub Antwerp in Belgium.
The sale is part of on-going trial mining evaluation of the Baoulé pipe.
So far around 8,830 carats have been recovered and two sales totaling 5,173 carats and generating revenues of over US$700,000 were completed in 2015.
The aim of the trial was to mine and process 100,000 tonnes of kimberlite, now over 70% complete and yielding results in line with expectations, the group highlighted.
Based on the current grade realised and previous drilling, Stellar said it is still targeting a resource in the region of 3 million carats at Baoulé.
