About Kunlun Growth: Your Trusted HPHT Partner at the Source.
A Message from Our Founder, Marshall Lee
“Having spent years deeply embedded in the intersection of Chinese manufacturing and global e-commerce, I witnessed a monumental shift: the rise of the lab-grown diamond. I saw the incredible innovation happening at the source in Henan—specifically in HPHT technology—but also saw the communication gaps. I founded Kunlun Growth to be the bridge for gem-quality HPHT diamonds. My mission is simple: to provide our partners worldwide with access to the finest D-E color stones that rival natural diamonds. At Kunlun Growth, we're not just trading stones; we are defining the standard for high-end lab-grown jewelry.”
