Lab Grown Diamonds and Gold

Lab Grown Diamonds

A diamond is a diamond is a diamond is a diamond.

Lab-grown diamonds are diamonds that are chemically, physically and optically identical to natural diamonds. They are diamonds that are grown in a laboratory using special processes. The only difference between natural diamonds and lab-grown diamonds is their origin.

Mining of natural diamonds is often done through large-scale mining operations that can have significant environmental impacts. These processes can destroy habitats and affect ecosystems. They involve removing large layers of soil, leading to deforestation, loss of biodiversity and significant CO₂ emissions. In contrast, the production of lab-grown diamonds does not cause this type of environmental damage because they are produced in controlled environments either through the High Pressure High Temperature (HPHT) process or through chemical vapor deposition (CVD). These methods allow diamonds to be produced in a much shorter time and with significantly fewer resources thus keeping the carbon footprint smaller as well. This makes them a more environmentally friendly option compared to their natural counterparts.

The advantages of lab-grown diamonds are evident. There is no overexploitation of nature and there is no exploitation of miners and divers in view of their often precarious working conditions. This makes them more ethical, environmentally friendly and socially friendly than naturally occurring diamonds. Of course, energy is used to produce the diamonds in the laboratory under high pressure and high temperatures. However the ecological footprint is ultimately kept smaller than with mined diamonds. Another advantage of lab-grown diamonds is the price. Customers get a larger stone and better quality for the same budget. In addition natural diamonds have already been used, for example, to pay for wars, finance rebels or engage in illegal arms trading, whereas lab-grown diamonds are conflict-free.

 

CVD (Chemical Vapor Deposition) process

In the process of diamonds produced using CVD technology seed crystals are placed on a diamond plate. The diamond plate is placed in an environment containing two carbon-containing gases: hydrogen and methane. As soon as pressure and temperature (800° to 900° Celsius) are generated the carbon elements are released from the gases and form a plasma cloud. This plasma cloud loosens the carbon elements on the diamond plate. In a few weeks layer by layer a rough diamond is created which is then processed and cut like any other diamond to then find its place in a piece of jewelry.

 

HPHT process (High Pressure High Temperature)

A lab-grown HPHT diamond is made from a small diamond seed. The diamond seed is placed in an environment containing carbon (the molecular component of diamonds) and a metal liquid. This helps the carbon to settle around the diamond seed. By applying the enormous pressure (70 bar) and high temperatures (1500° Celsius) under strictly controlled conditions the small diamond seed begins to grow atom by atom, molecule by molecule, mimicking nature's process. After a few weeks the whole process results in a rough diamond which is then worked and cut like any other diamond, to then find its place in a piece of jewelry.

 

Gold

We only use 18 karat gold in our jewelry. Recycled gold is a more environmentally friendly alternative to traditional gold mining, given the growing environmental and social problems, as well as the widespread child labor often associated with traditional gold mining. The recycling process requires significantly less energy than traditional gold mining which helps reduce emissions. In addition recycled gold reduces the need for new gold mining thus preserving natural resources. Gold mining often has devastating environmental impacts including deforestation, water pollution and loss of biodiversity; incidentally, these are very similar impacts to those that diamond mining has on the environment. The use of chemicals can also cause long-term damage to people and ecosystems. In many regions gold mining leads to conflicts between mining companies and local communities over differing claims to the resources and their use.

However the recycling process also presents its own challenges and it is important to do it responsibly. While recycling gold is less environmentally damaging than mining the chemical processes used (e.g. refining) can still have negative environmental impacts, especially if not carried out properly. The origin of the recycled gold can also be problematic. If the material comes from unsafe or unethical sources (e.g. illegal gold mining) this can undermine the positive aspects of recycling.
