"Our new supply agreement with HB creates true alignment between the producer and manufacturer for the first time. Rather than Lucara selling our +10.8 carat rough diamonds at the mine gate, we are putting this most valuable part of our production [accounting for ~70% of annual revenues] into manufacturing with HB and receiving final polished prices less a fee and the costs of polishing," Lucara CEO, Eira Thomas said in an emailed response to questions.
