Committed to eco-friendly and ethical development, we integrate sustainability into how our diamonds are grown, how our jewelry is made, and how our supply chain is run.
Local green power and energy-saving HPHT/MPCVD equipment minimize energy use per diamond.
Compliant waste treatment plus recovery and reuse of graphite, catalysts and precious metals.
Fully traceable rough diamonds that eliminate conflict and blood diamond risk, start to finish.
Clean Energy Production
We prioritize local Henan green power for lab-grown diamond manufacturing. All of our factories are equipped with energy-saving HPHT and MPCVD equipment, minimizing energy consumption per diamond unit.
Yiyang Wind: 940 million kWh / year
Neihuang Wind: 2 billion kWh / year
Shangqiu PV Power: 6 billion kWh / year
Xiaolangdi Hydropower: 5.5 billion kWh / year
Circular Resource Reuse
Our wastewater and exhaust treatment fully meet regulatory standards. We recycle and refine HPHT graphite and metal catalysts for reuse, recover precious metals from polishing dust and electroplating sludge, and mass-recycle K gold, platinum and other precious metals for reproduction.
Ethical & Compliant Supply Chain
With our own dual in-house production lines, every rough diamond is traceable from growth to finished jewelry — completely eliminating the risk of conflict or blood diamonds.
