Are your precious diamonds the ‘real deal’, or, were they grown in a lab ? Have you ever wondered ? We live in an age where many well known branded items are being recreated by ‘knock-off’ artists. Everything from ‘Louis Vuitton’ bags for ladies to ‘Nike’ running shoes.

In this article we will discuss lab diamonds vs real ‘mined from the earth’ diamonds, where do they come from, or how are they created, and, how can you know the difference.


Diamonds, Diamonds & More Diamonds

Diamonds have been a sign of wealth and power for centuries.

When it comes to diamonds, there are two main types: those that are mined from the earth, and those that are grown in a lab. Both types of diamonds are made of pure carbon, and they share many of the same physical properties. However, there are some key differences between the two.

Lab-grown diamonds are created using advanced technology, and they can be produced in a matter of weeks. In contrast, natural diamonds take billions of years to form, and they are mined from deep within the earth. As a result, lab-grown diamonds are often far less expensive than their natural counterparts.

According to a recent study, about 30% of diamonds on the market today are artificial or “lab-grown.”

Laboratory created diamonds have the same physical and chemical properties as diamonds mined from the earth, so they are very difficult to distinguish from authentic diamonds. However, non-identical diamonds usually have different optical properties, so they can be identified with a microscope.

So, how can you tell if a diamond is real or fake? One test is to use a magnifying glass or microscope to inspect the diamond for imperfections. Real diamonds will usually have small blemishes called ‘inclusions and hairline cracks, invisible to the naked eye, while fake diamonds will be flawless. Another test is to use a black light; real diamonds will glow blue under ultraviolet light, In addition, most lab-grown diamonds sold today are imprinted with a laser inscription that identifies them as artificial.

Jewelers Can Help

Any experienced jeweler will tell you that diamonds are not all created equal. In fact, there are many fake diamonds on the market, and it can be difficult to tell the difference between a real diamond and a fake. However, jewelers have a few tricks up their sleeves when it comes to identifying a real diamond. For starters, they will often use a laser to look for flaws in the stone. If the diamond is real, the laser will bounce off the surface of the stone. However, if the diamond is fake, the laser will pass right through it. jewelers will also use a microscope to examine the diamond more closely. Real diamonds will have a distinctive patterns of inclusion, while fake diamonds will often have more uniform patterns.

By taking your diamond to a jeweler, you can gain peace of mind knowing that your investment is authentic.

Our Personal Diamond Experience

Recently, we had my wifes diamond engagement ring sized at a reputable jeweler in our city. It was out of our hands for 2 days while the resizing was done.

My wife is from the Philippines where it is very difficult to find a jeweler that you can trust to resize a ring without replacing your authentic diamond with a fake. So, as you can imagine, we were highly suspicious.

We took her ring into a well know national jeweler and asked them to examine it and tell us if it was authentic or perhaps had been replaced with something synthetic. So you can imagine our anticipation as the jeweler first examined my wifes ring with a laser and then with a very powerful microscope. She showed us the inclusions or imperfections in the main diamond along with a very small crack that you would never see with your naked eye. These imperfections are unique to each real diamond. We were of course relieved to know that her diamonds were all original and authentic ‘from the earth’ diamonds, and had not been replaced with artificial stones.


As you can see, it is possible for even a novice to examine their own diamonds to determine their authenticity. To be doubly certain of course, you can take it to a reputable jeweler. As a side note, we were not charged for the examination when we took my wifes diamond ring in to a local jeweler. In a matter of about 15 minutes we had all our questions answered and more.

  1. Hi William! Very interesting post. I was surprised by some things here!
    First I didn’t know that diamonds could be grown in a lab, wich is amazing for me to know how technology has evolved!
    I was also very surprised to know that real diamonds take billions of years to form, I thought it was like a hundred years or so. You have very good knowledge about diamonds! It’s a good thing that jewelers can see the diference from a real diamond to a fake one.
    Anyways good post, very interesting! I learned something today. Thank you!
    Just one question are the two latest links relatable to the same subject? Because you didn’t explain in the post.


    1. Hey Julius, really appreciate your comments. Yes, it is quite incredible the way these
      ‘Perfumers’ put together fragrances including the three notes indicated. Its almost like when you drink something you will taste it right away, and then, there could be an aftertaste which is a little different.
      In regard to the notes, as you read, the middle or heart note is usually the one that identifies the fragrance, however, it will fade fairly quickly as the base note comes into play and remains the longest.

    2. Hello Chester, thanks so much for your comments, we appreciate them very much. Yes, it amazed me also to learn that a diamond can actually be created in a lab, WOW right ! If you research the selling price of these ‘lad created’ diamonds, you will find that they are not that much less expensive than genuine diamonds.
      The two links at the end of this article are not directly related other than the one on the 3D printing of jewelry explains how jewelers can not create their mold for jewelry pieces using a 3D printer. To me, this is technology at its best. 3D PRINTING OF JEWELRY The other link is an in depth look into Authentic Navajo Turquoise Jewelry AUTHENTIC NAVAJO TURQUOISE JEWELRYincluding some of the superstitions associated with these pieces. Very interesting indeed.

  2. Hi William,
    Thank you for this interesting post comparing Lab Diamonds Vs Real Diamonds. I have heard of industrial diamond saws, are they using these same lab diamonds? Like you, I am always concerned with having jewelry repaired. Many years ago, I had a watch that belonged to my dad and it contained jewels inside the movement. I worried about them when I took it in for a cleaning. But, I never would have know if they changed them or not. Now, after reading you articled I have learned a few things about being able to tell the difference. Thank you William.

    1. Hey Chas, thanks so much for stopping by and leaving your comments. To answer your question, yes, the diamonds used on the tips of diamond saw blades are actually created in a laboratory, a very interesting question. Thank you for asking it.

      Yeah, especially in the Philippines where my wife is from, she would never give her diamond ring to a jeweler for resizing. They would replace the diamond with something artificial.

      Sometimes I guess, we would never know if they replaced even the jewels in your dads watch.
      So glad you enjoyed the article. I have included a link to our newest post that you may be interested in.

      Take care,

  3. Hi William, what an interesting read! There is so much more to diamonds, to know or not to know exactly what you are buying and how to double check it’s authentic!

    I remember when I went with my son to look at diamond engagement rings and do comparisons. Well we were lucky enough for the jeweller to go into deep discussion about the diamonds size, facets and weight and it’s not always how big you go, but how precious the cuts, how light reflects, weight and of course how much you are prepared to spend!

    Once you buy, you even get a certificate of proof of the value for insurance purposes.
    My son chose wisely, not to complicated, not too big or too small, but just right and when he finally proposed to his girlfriend, she was blown away on how beautiful her ring was!
    Thanks for sharing. Keep up the good work!

    1. Hey Julia, thanks so much for stopping by and leaving your comments. We appreciate it.
      Yes, you are right, there is a lot to know about diamonds and most folks when purchasing something so valuable know very little about them. It was great that the jeweler took the time to educate you and your son before his purchase. I think it is especially important these days as most lab-created diamonds are almost as expensive as earth mined diamonds.
      Congratulations on your sons engagement. That is awesome !
      I have left a link to another recent post that you might also be interested in.

      Take care,

  4. It´s crazy how far our technology has developed so we can even copy in weeks what nature can only produce in billions of years. If I might be able to buy a diamond some day it seems I have to be careful to not be played, haha!
    Thanks William for the information! Take care!

    1. Hey Thimo, appreciate the comments, thank you.
      Yes, you are absolutely right, technology is soaring ahead at break neck speed for sure.
      Lab created diamonds are so close to the earth mined stones that the average shopper may not be able to notice the difference. Glad you picked up some valuable information.
      Thanks !

  5. This article is worth reading. I did not know that synthetic diamonds were produced. I was never interested in owning a diamond, but the facts about finding a diamond in nature, grinding, cleaning, all that interests me. Actually, I am interested in how our nature works and what kind of beauty and miracles it gives us. Thanks again for the nice post.

    1. Ana, thank you for stopping by and leaving your comments. Yes, earth mined diamonds are indeed quite a miracle, taking hundreds of years to form beneath the earths crust, with the appropriate heat and tremendous pressure.
      Then the finishing process begins to turn a rough stone into what we are all familiar with when looking at diamonds in the jewelry store. AMAZING !
      Lab created diamonds are of course made in a laboratory in much less time under very controlled circumstances.
      They are almost as brilliant as their earth mined cousins and far less expensive to produce.

  6. Wow! I really didn’t know that the presence of fake diamonds is about 30%. That’s a crazy high number. Also, that one cannot recognize the differences with the naked eye…what the heck? That makes it almost impossible for novices to know if they are both real-minded ones or lab-grown diamonds. maybe this is a stupid question, but are those lab-grown diamonds of less quality? In any case, thanks for this great post.

    1. It is a fact that Lab created diamonds are indeed growing in popularity. Well known brands like Pandora are only using lab diamonds in their jewelry and we will see more and more others doing the same. The benefits are obvious, much less costly to produce than their earth mined cousins, far less environmental impact and they are also every bit as beautiful, having almost identical refractory indexes. These lab diamonds are made of the same material as earth mined diamonds so they are just as hard.
      Fortunately most retailers are identifying the jewelry they have containing lab diamonds so the consumer will know exactly what thy are buying.

  7. Hey William,
    Great article here! So much knowledge about diamonds to take in from here. I never knew diamonds could be gotten in the lab in a matter of weeks. This shows how much our technology has evolved. I’m certain that lots of work go into the growing of diamonds in the lab even though it takes weeks. Let alone a billion years for them to form by nature and be mined from the earth.
    No wonder diamonds are called precious stones. But then I’m surprised that only 30% of diamonds on the market today are artificially grown since it takes so many years for them to form naturally. I expected it to be maybe up to 70% or more. So when were the natural ones mined and do they still exist?

    1. Hi Femi,thanks so much for your comments. Yes, it is amazing that such beautiful diamonds can be created within a few short weeks in a lab. These gems are every bit as beautiful as genuine earth mined diamonds with very little difference.
      The quantity of lab created diamonds is increasing very quickly as they become more accepted by consumers as a very authentic alternative to their natural cousins. I really do not think that it will be long before the majority of diamonds available in the market will be those created by man.
