Whereas diamond miners have begun to control themselves to keep away from the worst of the adverse impacts of the trade, their operations stay considerably dangerous to the surroundings – chemically and bodily equivalent minerals might be reliably synthesized at present as alternate options.

How Does Diamond Mining Hurt the Atmosphere?
Current research verify that vital environmental harm remains to be brought on by mines supplying the remaining demand for mined diamonds.
A 2019 report on diamond mining in Sierra Leone discovered that mines’ bodily and chemical outputs had been the supply of significant hurt to the native surroundings. This air pollution has made farmland unfit for crop manufacturing, contaminated groundwater, dried up water wells, and cracked the partitions of homes.
Noise air pollution was additionally discovered to be at a harmful degree round diamond mines within the area.
The broader impacts of this environmental harm had been observable as properly. Well being issues brought on by occupational accidents mixed with larger charges of incidence of illnesses like diarrhea and malaria took their toll on communities round diamond mines.
Probably the most vital influence discovered within the report was the diamond mining trade’s adverse results each on the supply of water sources and water high quality within the native space.
Water shortage was attributed to the large depth of diamond mine pits, decrease than the water desk and the underside of native wells. This additionally affected water high quality, which in flip is an element within the larger incidence of instances of malaria, respiratory infections, and pores and skin illnesses in native communities.
The mines additionally prompted airborne emissions at every stage of their cycle, and particularly within the exploration, improvement, development, and operation phases. Waste piles from mining operations comprise small-sized particles that get simply picked up and dispersed by the wind, polluting close by ecosystems.
In a 2020 research, the environmental impacts of diamond mining within the Democratic Republic of Congo (DRC) had been evaluated. The research centered on alluvial diamond mining.
Why lab-grown diamonds are higher than mined diamonds

Alluvial diamonds had been eroded from their major supply (Kimberlite) naturally after which deposited in a brand new surroundings by waterways. They’re present in riverbeds and floodplains.
Mining alluvial diamonds causes vital environmental harm. Deforestation, river air pollution, water shortage, and harmful working situations are all widespread within the mines analyzed for this research.
Artificial Diamonds are Materially Equivalent to Mined Diamonds
Chemically and bodily, artificial or lab-grown diamonds are equivalent to diamonds retrieved from mines. They’re made in the very same manner from the very same materials: pure, crystallized carbon in an isotropic three-dimensional construction.
Consultants in valuable stones are unable to inform the distinction between artificial and mined diamonds, though the letters “LG” (lab-grown) are generally inscribed on the base of artificial stones.
In nature, diamonds are shaped deep underground as warmth and stress exert themselves over carbon over a really very long time. Subterranean volcanic eruptions transfer them nearer to the earth’s floor, the place they’re excavated.
Within the laboratory, this course of is recreated with a diamond fragment positioned in a sealed chamber. The chamber is heated to excessive temperatures, corresponding to temperatures on the floor of the solar.
Gases fill the chamber and add crystallized carbon layers to the diamond over a interval of some days.
In 2018, america authorities’s Federal Commerce Fee (FTC) made a landmark ruling that included artificial diamonds in the identical definition as mined diamonds.
How are Artificial Diamonds used Right this moment?
The quite a few purposes for artificial diamonds at present are testomony to the truth that they’re a like-for-like alternative for mined diamonds, and will eradicate the necessity for an environmentally and socially catastrophic diamond mining sector solely.
Industrial purposes of artificial diamonds make use of their hardness. Machine instruments and reducing instruments particularly make use of this property, utilizing diamond-tipped edges to shine, lower, or put on away some other materials.
Diamond-tipped drill bits, diamond powder abrasive, and different makes use of in machining and instruments make up the most important demand for artificial diamonds within the trade.
Further Reading: Reliable Diamond Analysis Performed By FTIR Spectroscopy
In electronics, artificial diamonds are used as warmth sinks for high-power lasers, laser arrays, and high-power transistor gadgets. This is because of their excessive thermal conductivity which – as is never the case in most supplies – coexists with negligible electrical conductivity.
Arduous, chemically inert artificial diamonds with excessive thermal conductivity and a low coefficient of thermal enlargement (CTE) are additionally well-suited for purposes in superior optics. There isn’t a different materials that beats artificial diamonds for efficiency in home windows transmitting infrared and microwave radiation.
The falling worth level and rising high quality for artificial diamonds has led to many optics techniques changing zinc selenide with pure carbon in high-power CO2 lasers’ output home windows.
Artificial diamonds are being explored as potential semiconductor supplies as properly. Doping artificial diamonds with boron or phosphorus particles produces a compound with semiconductor properties, and will type the idea of much less dangerous strategies of semiconductor manufacturing sooner or later.
There isn’t a motive to purchase an artificial diamond, aside from the vagaries of style and speculative funding. Neither of those is trigger sufficient for the numerous environmental and social harm brought on by the diamond mining trade.
