Global lab-grown diamonds market share 2019, by country

China is by far the world's largest producer of lab-grown diamonds, accounting for an estimated 56 percent of the global lab-grown diamond market based on production in 2019. Lab-grown diamonds are chemically and structurally identical to naturally occurring diamonds, but can be produced in labs within weeks rather than billions of years. They also cost approximately 30 to 40 percent less than natural diamonds.

中国迄今为止已成为全球最大的实验室培育钻石生产国，根据2019年的产量计算，其市场份额约占全球实验室培育钻石市场的56%。实验室培育钻石在化学和结构上与天然钻石完全一致，但可在实验室中于数周内完成生产，而非历经数十亿年的自然形成过程。此外，其价格约比天然钻石低30至40个百分点。
