Which Kind of Diamond Is Better for the Environment?
Which kind of diamond is better for the environment and the world we live in: a diamond from a traditional mine or one made in a laboratory?
Some recent reports suggest the answer may not be so clear. At the very least, these reports provide evidence of tensions between two different sectors of the diamond industry.
Lab-grown diamond companies say they are more ethical and cause less harm to Earth's environment.
The traditional diamond sector notes that its businesses help the communities where they operate mines. It says they provide jobs, help build roads and other infrastructure and make investments in conservation.
Some companies, such as De Beers, work on both sides. De Beers sells natural and man-made diamonds.
In the United States, the Federal Trade Commission (FTC) investigates reports of deceptive, or misleading, advertising. In April, the commission sent warning letters to eight lab-grown diamond companies.
One of the FTC's concerns was the use of the word ‘eco-friendly,' and similar terms, to describe diamonds made in a laboratory. The lab-grown process requires very high temperatures and uses a lot of energy.
Trucost is a company that estimates the costs of using natural resources. Asked by the Diamond Producers Association to study the issue, Trucost found the carbon intensity of natural diamonds was lower than lab-grown diamonds.
The Trucost report did note that diamond miners should reduce their effect on the environment by using more renewable energy, such as wind power and sunlight.
The Reuters news agency reported that the International Grown Diamond Association did not immediately respond to requests for comments about the story.

I don't know if this is his strategy, but at the very least it is his method.
At the very least, you can then say that you tried.
最近的一些报告显示，答案可能并不十分明确 。至少，这些报告提供了钻石界两个不同行业之间关系紧张的证据 。
传统钻石行业则指出，他们的业务帮助了矿山开采的周边社区 。他们提供了就业机会，帮助修建道路和其他基础设施，并在环保方面进行了投资 。
戴比尔斯（De Beers）等一些公司在两个行业均有涉猎 。戴比尔斯既经营天然钻石也出售人造钻石 。
在美国，联邦贸易委员会(FTC)调查了欺骗性或误导性的广告报告 。今年4月，该委员会向八家从事实验室培育钻石的公司发出了警告信 。
该委员会关注的问题之一是，他们在描述实验室培育的钻石时，使用了“环保”等类似术语 。实验室培育钻石的过程需要高温环境以及大量的能源 。
Trucost是一家评估自然资源消耗的公司 。应钻石生产商协会(Diamond Producers Association)的要求，Trucost对这一问题展开研究，他们发现天然钻石的碳强度低于实验室培育的钻石 。
