Lab-Grown Diamonds vs Diamond Simulants

What is a lab-grown diamond?

Lab-grown diamonds, also known as synthetic or cultured diamonds, are gaining popularity in recent days since they have the same physical, chemical, and optical properties as mined diamonds. They are made in a lab in contrast to being formed under the ground.  In fact, industry experts can hardly tell the difference without special equipment that scans for patterns and impurities.

Now, how would you know if a lab-grown diamond is the one for you? Let’s take a look at the pros and cons.


  • The price is one big benefit of lab-grown diamonds. They are much cheaper than their earth counterparts, about 10 to 30 percent less than a natural diamond of similar size, color, and clarity.
  • While it hasn’t been fully studied yet, lab-grown diamonds are most often cited as environmentally sustainable, since it takes less energy to grow a diamond in the lab. Plus, they don’t require mining, which degrades the environment and often puts workers in dangerous or unsanitary conditions. 
  • Lab-grown diamonds are ethically sourced. The issue with “blood diamonds” and “uncut gems” is extremely etched in many consumer’s minds. From child labor practices to human rights violations, diamond mining delivers both controversy and conflict. So it is reassuring to know that with lab-grown diamonds, you can be confident that your gem did not support wars or exploitation in any way.


  • Lab-made diamonds are not as bizarre as natural diamonds are. Each traditionally mined diamond is a unique work of nature’s art, while lab-grown diamonds are mass-produced in factories. A diamond’s mystery and charm may be affected because of this.
  • Just as lab-grown diamonds support ethical sourcing, they also take jobs away from workforces and laborers. A diamond mine is a huge profit to the economy of the host country when run responsibly, so the jobs and income that the mine brings can help many people from poverty.
  • Many people still don’t fully understand what a lab-grown diamond is. Due to common misinformation about them, people might think you’ll be getting a fake diamond instead of the real thing.

What is a diamond simulant?

Are simulated diamonds and synthetic diamonds the same? Definitely not! Simulated diamonds—or diamond simulants—can be gorgeous but they don’t possess the chemical and physical properties of actual diamonds. Simply put, lab-grown diamonds are real diamonds, while simulated diamonds are not. Although the difference is simple, it still confuses a lot of people. But if you’re unsure whether a seller is misrepresenting a simulated diamond as a synthetic, then you have to look out for the price tag especially if it’s unusually low.

If you’re considering a diamond simulant, read our short guide of the most popular diamond simulants:

Cubic Zirconia (CZ)

Cubic zirconia is one of the most popular diamond simulants and is often regarded as an inexpensive diamond alternative. However, it is less durable and can discolor over time, unlike real diamonds.

Synthetic Moissanite

Moissanite offers refractive qualities better than the majority of diamonds, but it’s extremely rare. Because of this, scientists and experts found a way to grow Moissanite in a lab using tiny silicon carbide crystals under pressurized heat to create a synthetic one. As a result, synthetic Moissanite is almost as durable as a real diamond. It’s also a plus that this gemstone looks almost identical to an actual diamond!

White Sapphire

Although blue is the most sought sapphire stone, it also comes in many colors. White or colorless sapphire is often used as a diamond alternative. It looks very close to a diamond, although it differs in terms of hardness, durability, and refraction. Moreover, white sapphire is prone to scratches since it is four times less hard than an actual diamond. Despite its difference from a real diamond, natural colourless sapphire is a relatively affordable gem if you’re looking for a natural stone!

Now that you’ve been briefed about these diamond alternatives, the best option relies on your decision alone. Whether you’re searching for a lab-grown or a simulated diamond, you can use our shopping recommendations below to make sure you’ll be getting high-quality gems.
