Lab Grown Diamonds

A Simple Guide To
Lab-Grown Diamonds

A Diamond By Any Other Name.
Lab-Grown Diamonds have generated plenty of interest, and almost as much confusion! They are known by many names including Engineered Diamonds, Cultured Diamonds, Man Made Diamonds, even Evolved Diamonds.  No matter how you refer to them, their facts remain the same. At Mark Loren Designs, we want to share those facts with you.


Yes, They Are “Real” Diamonds.
A laboratory-grown diamond has the same optical, chemical, and physical properties as a natural diamond. It has the same chemical composition, refractive index, and 4Cs. To the naked eye, there is virtually no difference between a natural mined diamond and a lab-grown diamond. In fact, they are so difficult to differentiate, it’s critical that jewelers offer total disclosure when selling lab diamonds. The only difference between a lab-grown diamond and a mined diamond is how it originates. Lab diamonds are, well, grown in a lab; traditional diamonds are formed by natural processes under the earth’s mantle.


Lab-Grown Diamonds Are Not “Simulated” Diamonds.
Part of the confusion lies in the fact that people tend to think of lab-grown diamonds as simulated. Simulated diamonds are made of Moissanite, Cubic Zirconia (CZ), White Sapphire and similar materials which do not have the same physical and optical properties as diamonds. Simulated diamonds* are meant to resemble mined diamonds, but they are not diamonds in any sense of the word.


How Are Diamonds Grown?
Lab-grown diamonds are created or “grown” by recreating the same conditions that form mined diamonds, but in a highly controlled laboratory instead of beneath the earth’s mantle. Using advanced technology – either extreme pressure and heat or a special deposition process – lab diamonds are grown from the tiny carbon seeds of pre-existing diamonds.


Why Buy A Lab-Grown Diamond?
Lab-grown diamonds aren’t for everyone.  But they are a great alternative for buyers with specific priorities. As jewelers, we appreciate the unique benefits of both mined and lab-grown diamonds. That’s why we want to share our knowledge to help our customers make an informed choice. That said, there are some unique benefits offered by lab-grown diamonds:

  • Remarkably Beautiful
    Lab diamonds have the same physical, chemical, and optical properties as mined diamonds. Some of the most spectacular diamonds in the world are lab-created and celebrated for their incomparable beauty.
  • Eco-Friendly and Sustainable
    Lab-created diamonds are sustainable diamonds.  Because they are grown in a lab, they are the epitome of ethically sourced and have a very small carbon footprint with no environmental impact.
  • Genuine Value.
    Lab diamonds provide an excellent value when you compare them to a mined diamond of similar quality and size.  They are optically identical and can be purchased for up to thirty percent less than mined diamonds.


The Bottom Line.
Lab-grown diamonds are neither better nor worse than mined diamonds.  They simply offer customers an option, and options are something we think our customers deserve.
