There are several benefits to using lab-grown diamonds. They are a better choice compared to mined diamonds because workers do not need to work in terrible conditions. In the past, some diamonds came from mines that operated in war zones, particularly in West Africa during the 20th and 21st century. When customers buy a diamond produced in a laboratory, they don’t have to worry about the ethical problems of how the stone made its way to the market.
使用实验室培育钻石有一些好处。与开采的钻石相比，它们是更好的选择，因为工人们不需要在恶劣的条件下工作。过去，有些钻石来自于战区营运的矿井，特别是二十世纪和二十一世纪的西非。当消费者购买实验室生产的钻石时，他们不必担心钻石如何进入市场的道德问题。
