Company Profile

Better Star — Pioneering Lab-Grown Diamond Innovation

Founded in Shenzhen in 2014, Better Star began as a research-focused startup dedicated to advancing lab-grown diamond science. Over a decade, we have grown into a fully integrated diamond enterprise — spanning cultivation, cutting, jewelry manufacturing, professional training, and global distribution.

We believe lab-grown diamonds represent the future of the industry. Identical to mined diamonds in every material aspect, yet more sustainable, more traceable, and far more accessible — they democratize brilliance without compromise.
