Our Story
Yinzheng Gems was founded in 1997 in Wuzhou, Guangxi – the world's capital of man-made gemstone cutting and trading. What started as a small family workshop has grown into a trusted supplier for jewelers and designers worldwide.
For over 27 years, we've focused on one thing: precision-cutting lab-grown gemstones with care and consistency. We don't mine. We don't middleman. We cut, polish, and craft – all under one roof.
In 2019, we embraced global e‑commerce. Today, our store serves customers in 30+ countries, with a 98.8% response rate and average response time under 3 hours.
