Real diamonds, but created in a lab (and cost less). Pros and cons of man-made diamonds.<\/h2>\n

It has been talked about for years, but many people still don’t have a clear idea of \u200b\u200bwhat stones are called lab grown diamonds.<\/strong> If you are looking for a quick and concise description of artificially produced diamonds, here we are. Basically, there are two methods to produce man-made diamonds, but in both cases the gems are identical, from a chemical point of view, to natural stones. But the similarity ends there.<\/p>\n

The name of the diamonds<\/strong>
\nBut, first of all, what are these diamonds called? In English the definition lab grown is the most used, especially by the marketing of those who produce or sell these synthetic diamonds. The idea that diamonds grow in the laboratory like tomatoes in a greenhouse offers a greener view of the product. The communication of those who produce and sell them is based precisely on the idea that diamonds created in the laboratory (but in reality they are factories, as for any other product), are more sustainable. Right? Wrong? We see.<\/p>\n

Sustainability<\/strong>
\nA natural diamond, created 2 or 3 billion years ago by the movement of the earth’s crust, is the result of the incredible pressure caused by the shifting of continents. Natural diamonds are therefore found under the ground. To be mined, diamonds must be searched deep or through large excavations in remote areas. Of course this activity, even if it is well controlled today, cannot be defined as sustainable. But, on the other hand, we must not forget that the extraction of natural diamonds also offers a livelihood for thousands of families in poor areas, such as Africa. Finally, any smartphone that you have in your pocket is the result of the extraction from the earth of a large number of minerals and no one is scandalized.<\/p>\n

In any case, is it true that lab-created diamonds are green? It depends. First of all, man-made diamonds require an enormous amount of energy to be produced. The vast majority of these diamonds are produced in China and India, but also the United States and Israel, and in many countries, coal-fired plants still represent the predominant source of energy. The emissions caused by the production of lab grown diamonds cannot be considered completely green. Furthermore, few people are needed to produce synthetic diamonds and, therefore, their positive contribution to the social economy is very low.<\/p>\n

How are they produced?<\/strong>
\nDiamonds that come out of a laboratory are produced using two very different methods: CVD (chemical vapor deposition) and HPHT (high pressure at high temperature). Currently the CVD system seems to prevail and, according to some, even offers a better result. So, if you want to buy a jewel with synthetic diamond, you can take the curiosity to ask what type of factory it was produced from. However, both methods use the same basic material: carbon.<\/p>\n
