The company was established in 2010 and is headquartered in the Zhecheng High-Tech Development Zone in Shangqiu, Henan Province, an area designated as a national high-tech industrialization base for superhard materials and products. It is listed on the Shenzhen Stock Exchange under the stock code 301071. The company's business covers three main product series: diamond single crystals, diamond micropowder and lab-grown (cultured) diamonds. These products are used in precision manufacturing, geological drilling, aerospace and defense, photovoltaic new energy, third-generation semiconductors, and jewelry. Liliang Diamond describes itself as one of the leading enterprises in China's superhard materials industry, with more than 100 scientific researchers, six wholly owned subsidiaries, seven major research platforms and over 100 proprietary core technology intellectual property rights. Liliang Diamond's history reaches back to 1990, when the first micropowder factory was established in Zhecheng County to begin diamond micropowder operations. By 2009 the micropowder business had become a major domestic supplier. In 2010 Henan Liliang New Materials Co., Ltd. was founded, extending the industrial chain into diamond single crystal production. The company produced its first jewelry-grade lab-grown white diamond in February 2016, completed its shareholding reform in March 2016 and was renamed Henan Liliang Diamond Co., Ltd., and began developing international lab-grown diamond markets. It listed on the Shenzhen Stock Exchange in September 2021. After listing, the company invested in new projects and expanded its industrial chain, establishing subsidiaries including Shangqiu Liliang Diamond Technology Center Co., Ltd. (December 2021), Hainan Liliang Diamond Co., Ltd. (April 2023) and Yangzhou Liliang Diamond Co., Ltd. (November 2023). In August 2022 it partnered with the jewelry company CHJ Jewellery (潮宏基) to create and operate a lab-grown diamond brand. Member enterprises are distributed across Shangqiu, Shenzhen, Hainan, Hong Kong and Yangzhou. The company's stated vision is to build a world-class enterprise in the superhard materials industry.

Liliang Diamond's corporate history is presented by the company in five phases. The germination phase (1990–2009) began in 1990 with the establishment of the first micropowder factory in Zhecheng County, starting diamond micropowder operations. By 2009, the micropowder business had grown into a major production supplier in China's diamond micropowder industry. The start-up phase (2010–2012) began in 2010 with the founding of Henan Liliang New Materials Co., Ltd., which extended the industrial chain into diamond single crystal production. From 2010 to 2012 the company achieved batch production of diamond single crystal products. During the innovation development phase (2013–2016), the company mastered independent core key technologies through continuous technological innovation, expanded its industrial scale and improved risk resistance. In 2013 it fully mastered independent production technology for diamond raw and auxiliary materials. From 2013 to 2016 it continuously added equipment, expanded capacity, improved product quality through technological innovation and increased market share. The enterprise development phase (2016–2021) saw the company complete its industrial chain and form three core product systems. In February 2016 the company's first jewelry-grade lab-grown diamond (white diamond) was born. In March 2016 it completed its shareholding system reform, was renamed Henan Liliang Diamond Co., Ltd., and began developing international lab-grown diamond markets. In 2018 its subsidiary Henan Baojing New Material Technology Co., Ltd. was established. From 2016 to 2021 the company conducted in-depth research and development of lab-grown diamonds, achieving successive breakthroughs from small diamonds to 1 carat, 3 carats, 5 carats and 10 carats. In September 2021 the company was listed on the Shenzhen Stock Exchange, entering the capital markets. In the rapid development phase (2021–2023), following its listing the company extended its industrial chain around its main business, expanded industrial scale, invested in new projects and developed a world-renowned lab-grown diamond brand, significantly enhancing brand influence. In December 2021 its subsidiary Shangqiu Liliang Diamond Technology Center Co., Ltd. was established, building a new lab-grown diamond R&D and production base in Suiyang District, Shangqiu. In August 2022 Liliang Diamond partnered with CHJ Jewellery to create and operate a lab-grown diamond brand. In April 2023 its subsidiary Hainan Liliang Diamond Co., Ltd. was established to develop domestic and international downstream jewelry markets for lab-grown diamonds.
