Moissanite vs Lab Diamond: Breakdown and Comparison

Moissanite vs Lab Diamond: Breakdown and Comparison

Moissanite vs Lab Diamond

Diamond alternatives are becoming the most sought-after gemstones for wedding and engagements rings due to the issues with natural diamonds. You can find both Moissanite and Lab-Created Diamonds at far less cost and environmental impact than diamonds, but which is better? Let’s compare Moissanite and Lab-Created Diamonds.

The Main Differences Between Moissanite and Lab-Created Diamonds


  • Moissanite is silicon carbide, whereas Lab Created Diamonds are carbon.
  • Moissanite is formed from processes to create a large crystal, whereas Lab-Created Diamonds form around a natural seed diamond.
  • Moissanite’s hardness on the Moh scale is around nine points five, whereas Lab Diamonds are the same hardness as natural diamonds and are a perfect ten on the Moh scale of hardness.
  • Moissanite is a diamond alternative; it is not a diamond, whereas a lab-created diamond is still one hundred percent a diamond.
  • Moissanite is mostly colorless, whereas a lab diamond can be any color of the rainbow.
  • Moissanite is grown specifically so that it doesn’t have inclusions, whereas Lab Diamonds can have inclusions.

What is Moissanite?

Moissanite is silicon carbide, a colorless, sparkling gemstone that Henri Moissan discovered. He initially thought that crystals that he found in a meteorite depression were diamonds. Still, after studying the crystals for several years, he discovered they were silicon carbide instead of carbon. Later a research facility created a process to create silicon carbide single crystals, and a gemstone company named Charles & Clovard patented the use of Moissanite in jewelry. Recently those patents have expired, and the use of Moissanite has been opened up to the world through any jewelry company that wishes to market it. Only in the last few years have you been able to purchase Moissanite from companies other than Charles & Clovard.

What is Lab-Created Diamond?

Lab-Created Diamonds are diamonds in every way except in where they are created. Natural diamonds were made billions of years ago deep underground and were brought to the surface through volcanic eruptions and earthquakes. Lab Diamonds are seeded using small diamonds put into machines that create the heat and pressure that natural diamonds were subjected to. Atom by atom, they grow in size and form the lab-created diamond. Lab diamonds are not valued as much as natural diamonds because, essentially, they are man-made and can be created on-demand. However, lab-created diamonds are diamonds in hardness, color, clarity, carat, and element.

Similarities Between Moissanite and Lab-Created Diamonds

Both gemstones take approximately six to ten weeks to grow and form in the lab. Diamonds are billions of years old; they were formed long, long ago and were created thousands of miles under the surface of the planet. Lab-Created Diamonds do use real diamonds to seed the diamond to grow around. Moissanite is lab-created in a process that creates large crystals to form. 

Both Moissanite and Lab-Created Gemstones are thermochromic, a test that the gemstones can change color under intense heat. Heat both gemstones to over one hundred fifty degrees, and they will change color for a length of time until either they are exposed to UV light, or they cool down to room temperature. This process rarely turns the gemstone that color permanently. 

Both gemstones are incredibly hard gemstones and are appropriate to wear every day as they will withstand the bumps and knocks, chemicals, soaps, and skin oils that are a part of everyday wear. Moissanite is a little easier to keep clean because it is a form of silicon, but either stone repels chemicals and dirt without being damaged by them.

Question: How Long Does it Take for Lab Diamonds to Grow?

Answer: Lab diamonds take about a month to grow. The longest to grow are white diamonds; the larger the size, of course, the longer the time frame is needed. It takes about two weeks to grow a diamond to a one-carat size. On the other hand, blue and yellow diamonds only take five to ten days to grow. This is all much faster than the billions of years that it took for natural diamonds to grow. 

Question: Will Lab-grown Diamonds Get Cheaper?

Answer: With advances in technology, lab-grown diamonds may continue to get cheaper and cheaper as the process is developed over time. Currently, although lab-created diamonds are about fifty percent cheaper than mined diamonds, they will lose all their value immediately when purchased. Natural diamonds currently lose only about fifty percent of their value. Lab diamonds are not an investment stone whatsoever. 

Question: Does Moissanite Come From Space?

Answer: Moissanite was first discovered in a meteorite crater and has been determined to come from outside of our solar system. It has since been discovered that it does occur naturally on earth in minuscule amounts, making it one of the rarest natural minerals, even though it is lab-created for jewelry and industrial uses.

Question: Why Do Lab-created Diamonds Have Inclusions?

Answer: Lab-created diamonds may have inclusions in them because some cheaper ways to make the stone involve using molten flux. When this is used, metal impurities get trapped in the stone and create the inclusions that are seen in lab-created diamonds. The stones can also have a metallic reflection from the inclusion as well.

Question: Which Moissanite is Closest to a Diamond?

Answer: A round-cut or Brilliant cut Moissanite is the cut that resembles a diamond most closely. Brilliant cut stones reflect light and sparkle in a specific way, and Moissanite can be cut to closely resemble the same reflective pattern and fire that a diamond has.


I have been and always will be team Moissanite. I do love the sparkle and glitter of a diamond, and lab-created diamonds are just as beautiful, special, and unique as a natural diamond. However, Moissanite is more reflective, sparkling, and rainbow glitter than diamond, which is my favorite thing about them. My second favorite thing about Moissanite is its incredible cost value. Lab diamonds are still much more expensive than Moissanite, and I prefer to spend less money on beautiful quality jewelry. Neither gemstone will reflect a heritage piece or investment gemstone, but to wear daily and get pure enjoyment out of your jewelry, Moissanite is the definitive choice.
