"Responsible supplychain is based on the principle of unconditional disclosure of information on [a diamond's] conflict-free source and quality characteristics...at everystage of change of ownership, with the aim of promoting consumer confidence indiamonds." Additionally, the miner has adopted the new internationalDiamond Terminology Guideline issued by nine industry bodies, including theWorld Jewellery Confederation (CIBJO), the Antwerp World Diamond Centre (AWDC)and the Diamond Producers Association (DPA). The instructions clarify proper industrywording, including the use of "diamond" in reference only to natural stones,and "synthetic" or "laboratory-grown" when referring to man-made gems.
