If you own a piece of diamond jewelry, you may be curious to know if it is a naturally occurring or lab-created diamond. Rather than pay for a jeweler to tell you the answer, why not pick up a magnet to uncover the truth? Naturally occurring diamonds are formed when carbon deposits found deep in the earth are subjected to extreme temperatures and pressure, while lab diamonds are created using similar concepts and a little help from scientists. The majority of all lab diamonds in the world are created using two methods: the HPHT (High-Pressure High Temperature) method or the CVD (Chemical Vapor Deposition) method.
How Lab Diamonds Are Created
First introduced in the 1950s, HPHT diamonds are created by placing a small diamond seed in carbon and exposing it to extreme heat and pressure. While many still consider such “man-made” processes to be a dupe, these impressive diamonds are nearly identical to naturally occurring diamonds both physically and chemically. One of the most notable differences between these incredible look-alikes and naturally occurring diamonds is their metallic properties. Commonly featuring a yellow hue, HPHT diamonds are unique in that they are exposed to high levels of nitrogen when they are being formed. In addition, they typically have darker inclusions (i.e., the non-diamond material found in the diamond during formation) containing metallic elements. CVD diamonds are similar, however, they utilize a far different method similar to how diamonds form in interstellar gas clouds. You heard correctly; micro-diamonds can be formed in space! And while similar, CVD diamonds do not contain metallic properties like HPHT diamonds do. It is also worth mentioning that cubic zirconia have no magnetic properties as they are considered simulant diamonds, and do not share the chemical or physical properties needed to pass the diamond test.
Put Your Diamonds to The Test
If we have sparked your curiosity to see if that diamond ring is real, try this simple trick. Take a neodymium magnet, we recommend a 1/2" x 1/4" x 1/4" Bar Magnet, and place it next to your diamond. If the diamond is naturally occurring, no magnetic attraction will be present. If, however, your diamond is an HPHT lab-created diamond, you should feel the magnet's attraction to the diamond. Note that not all HPHT diamonds are created equally, therefore, the amount of inclusions will differ and may distort this test. While not foolproof, it is a fun way to test your diamonds at home!
