Real vs. Synthetic vs. Man-Made Diamonds

Posted on November 20th, 2019 by JoeG

There were and are still issues surrounding the Genuine vs. Synthetic (Cubic Zirconia & Moissanite) and now the much more difficult to detect, Lab-Created Man-Made diamond debate when it comes to diamonds. As diamond buyers in Chicago, we can usually spot a synthetic/fake almost immediately, but in some cases, it requires further examinations. To know if you’re diamonds are genuine, bring them in to determine the authenticity when it comes time to sell them.

Using Water

Get a glass and fill it with a healthy amount of water. Once the glass is filled, drop the diamond carefully into the glass and observe it. If the diamond sinks, it is real, but if it floats to the top or stays in the middle of the glass, your diamond is a fake one.

Using A Magnifying Glass

Looking through a magnifying glass allows you to spot any imperfections. If there are no imperfections, it’s likely you have a fake diamond. Real diamonds have imperfections, or another term you may be familiar with are inclusions. There are different types of diamond inclusions so make sure you contact us if you want to find out more about the diamonds you have.

Using A Black Light

Hold the diamond in front of a turned-on black light and if you can see a blue fluorescent light under the black light, you most likely have a real diamond. If you see a slightly green, yellow, or gray light, then your diamond isn’t real. However, you will best be able to discover if your diamond is real by visiting us and having an appraiser look at it.

Customer Testimonial

Had a Great Experience

"I drove all the way from the south side just to sell my silver to Chicago Gold Gallery because of the knowledge and professionalism I received on the phone. They gave me top dollar for my silver and were so fast and friendly. I definitely recommend this business!"

Can't say enough about this place.

This is the most welcoming, non-pretentious place to do business! I was researching where to sell sterling silver I had and ended up choosing here based on the other great reviews. They walked me through the whole process and answered my questions. I got a great price for my items & will go there again.

Love this place!

Chrissy & Joe are all super friendly and easy to work with. I trust them and they will do whatever they can to help you including giving you advice on what you have or what you should look for. I won't ever go anywhere else and I've recommended it to several friends.

I would do business with them again

I had a large collection of silver coins sitting in my safe deposit box for 15+ years. Chrissy was so friendly and helpful she even gave me advice about coins I didn't know. She was more than happy to help me for over an hour in between taking care of other customers. They really did give me top dollar for my coins. Whether you are new or a pro with coins, I can highly recommend you take them here!

Don't Hesitate to call...

I find that Joe at Chicago Gold Gallery consistently offers and pays more for my coins than coin dealers in Chicagoland. He's very nice and easy to deal with. Don't hesitate to call him and preferably visit him.
