What Exactly Are Man-Made Diamonds?

Lab created diamonds are different from simulated diamonds & mined diamonds in that they are grown by scientists in a laboratory. Scientists are able to simulate the Earth’s diamond creation process; however, instead of forming naturally below the earth’s surface in the Earth’s crust, scientists are able to create these man-made diamonds above ground. Lab grown diamonds are a great eco-friendly option because they have the same visual & chemical properties as mined diamonds, without causing detrimental effects on the Earth and nature. Additionally, lab created diamonds are typically better quality when it comes to the 4 Cs.

The reason lab created diamonds are becoming more popular is because of the technology behind it. Did you know that man-made diamond technology has been around for almost a century, but it wasn’t until this decade that scientists have been able to create perfect synthetic diamond imitations? That means that these ethical, conflict-free, lab grown diamonds are better than mined diamonds in every way. But we haven’t gotten to the price difference yet.

How Are Synthetic Diamonds Grown?

A chamber houses a “seed” that is engulfed in extreme heat and compacted in extreme pressure. This chamber is responsible for mimicking the natural diamond creation process, and it takes 6 to 10 weeks to fully create a man-made diamond. This is a lot quicker than the millions of years it takes diamonds to be created naturally. What are some common processes that are used by scientists to create a synthetic diamond?

Chemical Vapor Deposition (CVD) to Create Diamonds

Chemical Vapor Deposition, or CVD, is a process that produces high quality products from extremely thin films, to lab grown diamonds, to semiconductors. Without boring you too much with all of the nitty-gritty details, CVD produces circumstances that allow a diamond to form from a free-standing, flat diamond disc. What is neat about lab diamonds, besides the eco, ethical, and conflict-free aspects, is that other types of sp3-bonded carbon, aka diamond, can be created. This allows the creation of multi-use diamonds that can be used for high heats, scratch-resistance, and as non-stick surfaces.

CVD diamond creation has recently been optimized to not require as high of pressure, compared to past versions. Here are the 4 variations of CVD that are most commonly used in lab grown diamonds.

  • Low-Pressure CVD (LPCVD)
  • Ultra-High Vacuum CVD (UHVCVD)
  • Plasma-Enhanced Chemical Vapor Deposition (PECVD)
  • Microwave Plasma Vapor Deposition (MPCVD)

Synthetic Diamonds Created with High-Pressure High-Temperature (HPHT)

There are 3 main designs in High-Pressure High-Temperature (HPHT) – the belt press, the cubic press, and the split-sphere (BARS) press.

The Belt Press

The Belt Press was the original GE invention where 2 anvils, one on top and one on the bottom, pressurize the load to a cylindrical inner-chamber. The anvils provide electric current to the chamber and compress the object, ultimately forming a diamond.

The Cubic Press

A Cubic Press uses 6 anvils instead of 2, like The Belt Press, when it comes to manufacturing a diamond.  These 6 anvils create enough pressure to compact the diamond, which forms the carbon crystal.

The Split Sphere BARS Press

The BARS Apparatus is a cubic-shaped pressure transmitter that has a barrel filled with oil. The barrel becomes pressurized when it is heated and a diamond is formed.

What Is A Diamond Simulant?

By now, you may be thinking that simulated diamonds and synthetic diamonds are the same, but they are not! Synthetic diamonds are lab grown diamonds that are almost identical to mined diamonds, whereas diamond stimulants are much cheaper and much better looking. Though the optical, physical, and chemical properties of lab diamonds are the same as diamonds, it allows for flaws in color and clarity. A simulated diamonds’ optical properties are similar to diamonds, whereas their physical and chemical properties are more akin to cubic zirconia – and actually, CZ has a much better cut and overall sparkle. So, why would you want to waste your money on an over-priced synthetic diamond when you can save money so you can book a better honeymoon or go travel the world with the extra money you’ll have in the bank?


Why Choose A Glamour Life Simulated Diamond Over An Expensive Lab Diamond?

Why pay for an over-priced lab diamond when there are better options at Glamour Life Diamonds? Simulated diamonds are much cheaper than a lab grown or natural diamond and they will sparkle even more because of the quality of the cut and near-flawless stone.
