Before we get too far, I do need to say that the term "fake diamond" is not technically correct from a Gemologist's point of view. Any term that ends with the word "diamond" must be an actual diamond... such as synthetic diamond, man-made diamond, or clarity-enhanced diamond. If a gemstone that just looks like a diamond but it really is something totally different, then the term that must be used is a "diamond simulant" because it simulates a diamond. In this article, and only in this article, I will use the term fake diamond because it gives more of an impact.
It's been going on for a long time!
Hundreds of years ago, fake diamonds were made out of glass, and commonly referred to as "paste", this is the Italian term given to it because the molten glass had to have the consistency of pasta before it was pressed into the molds that formed the shape. There have been many other "fake diamonds" over the years but recently they have gotten really, really good.
A good gemstone gone bad....
According to the dictionary, fake has the same meaning as counterfeit. What changes a diamond simulant to go to the "dark side of the force" and become a fake diamond is the addition of the human emotion of greed. The diamond simulants by themselves are fine, actually I've seen some terrific pieces of jewelry made with Synthetic Cubic Zirconia or Synthetic Moissanite. The greed comes in when one person convinces another person that what they are looking at is a real diamond and that the diamond could be bought at a very good price.... and the seller will say that these inexpensive diamonds are only available now.... "this great deal is going away and you need to act right now!". You can get them right now because the seller is in real need of cash... or because the seller is so well connected into the jewelry business that they know how and where to buy diamonds, and in the process they "cut out the middle man" in order to get the best deals!
Many times the main reason that a diamond simulant can be passed off as a real diamond is because the buyer already has the belief that diamonds are overpriced, are a waste of money, are a rip off, and maybe the buyer really doesn't want to buy a diamond but needs to buy a diamond... so this leaves the buyer open to a seller who comes along and tells the buyer that a whole bunch of money can be saved by buying what "looks just like the real thing".
Diamond simulants have their place in the jewelry business. They are a good inexpensive choice for earrings, a pendant, or a pin. However, a clarity-enhanced diamond should also be something that you should consider for these types of jewelry. A diamond will always outshine any simulant I've ever seen!
Yeah, yeah... but how can you tell? Come on give me the magic test!
On the Internet, I have seen a lot of articles and videos on how to test if you have real or fake diamonds.... the same 6 lame "tests" have been regurgitated over and over again! And all of this fantasy about testing a diamond started with an overly self-promoting bonehead that published a book full of misinformation about diamonds! Only a very few people would be able to tell if a stone was a real diamond or a fake diamond by using these tests! And some of the tests could be destructive. The gemstones that look like diamonds that have been developed in the past 30 years are certainly impressive!
I remember when CZ (synthetic cubic zirconia) was first put on the market in the mid 70s, there were some jewelers who were running around crying that the end of the world was upon us. CZs are really not that difficult to separate from diamonds and Synthetic Moissanite is even easier. The best test is to look at the stone using 10X magnification, but you do need to know what you are looking at! In most jewelry stores, they have "easy to use" electronic testing devices developed to help in separating the simulants from the real thing. Sometimes it is difficult to know for sure when it comes to very small stones by just looking at them.
I love inclusions!
Diamond inclusions, the fun little things that are included inside of your diamond, are always nice to see. Not only does it give your diamond some character!... it will immediately help identify the stone as being a real diamond. Inclusions can be like a fingerprint and if you remember what your inclusions look like; you will be able to recognize your diamond just like you'd be able to recognize an old friend.
Maybe the only test that could be of any use is when you place the stone over some fine print and if you can see the text through the stone it may or may not be a diamond. So if you need to know if it is a diamond, go get a phone book, (plenty of fine print in there!) turn to the yellow pages, now look up a good local jewelry store, go visit them and if you ask nicely, they might be able to give you a "real or fake diamond" answer.
