Myths About Lab-Grown Diamonds

As lab-grown diamonds have grown in popularity over the past few years, many misconceptions have stemmed from the lack of education about these gems. To help provide a clearer understanding, let’s break down some of the most common myths circulating about lab-grown diamonds:

  • Lab-grown diamonds are “fake” diamonds

    While these gems are not born through the same geological process as a mined diamond, lab-grown diamonds are made from pure carbon crystal, or a “diamond seed”, and have the identical chemical composition as a diamond grown from the Earth. These gems can be considered as the “greenhouse flowers” of the diamond industry: identical appearance and composition compared to those grown in nature, but are born from within a controlled environment!
  • Lab-grown diamonds are cheaper to manufacture

    When mining a diamond, you have to include the costs of actually retrieving the diamond from the Earth’s surface (which can be found roughly 15 metres below). Although this cost is cut from the production of growing a diamond in a lab, manufacturers still have to create the same environment using advanced technology, which would cost the same as drilling for diamonds in the Earth.
  • Lab-grown diamonds and Cubic Zirconia diamonds are the same

    This is completely false. Lab-created diamonds are pure crystallized carbon diamonds grown in a laboratory environment. They have the same physical, chemical, and optical properties as an earth-mined diamond. Cubic Zirconia, on the other hand, is considered as a “diamond simulant”, meaning it just has the same appearance as a diamond. Here’s some additional information to further prove the difference:


  • Lab-grown diamonds have no resale value

    The main opposing argument from most diamond companies is that lab-grown diamonds lack any sort of resale value, compared to mined diamonds that are seen as monetary investments. The truth is that they both have similar resale values! All diamonds, whether grown in a lab or from the Earth, are subject to the same internationally accepted pricing system when being resold. This system, called the Rapaport pricing method, focuses on the “Four C’s” of diamonds when evaluating a potential resale cost: colour, cut, clarity and carat. If a diamond is lab-grown, it can be taken into consideration during price evaluation. Lab-grown diamonds are not completely worthless, as they are made out to be by companies of mined diamonds.
