Difference Between Diamonds And Cubic Zirconia

Diamonds are a beautiful way to add some sparkle and elegance to your collection. Cubic zirconia is a much less expensive man-made gem that appears quite like a diamond, but they are very different. Below are some tips on how to tell diamonds and cubic zirconia.

Appearance

This is the first step to determine a cubic zirconia trying to pass itself off for a diamond. While the two stones may look similar to the untrained eye, there are some subtle differences you should know. While many people incorrectly think a diamond should have a clear appearance throughout, skilled diamond fanatics understand that a 'white' diamond can still have a yellowish brown tint. This are what make the D-Z color scale- a M color white diamond would be slightly yellower than a F color diamond, for example. Cubic zirconia is more likely to be completely colorless which is a tell-tale sign it isn’t a diamond. Another notable difference is that a diamond will have inclusions throughout the stone which is a sure sign it is real. Aside from the actual color of the stone, look at the color of the light as it enters and escapes the surface of the stone. If you turn both a diamond and a CZ upside down, the bottom of a diamond will give off tjhe entire rainbow of color reflections, whereas CZs usually have more exclusively orange and blue flashes.

Composition

While these stones may look somewhat similar, the composition is drastically different between them. When looking to tell the difference between diamonds and cubic zirconia, consider the hardness. A diamond is the hardest stone known to man while a cubic zirconia has a much lower rating of hardness. Diamonds are made of carbon which lends to their brilliance and hardness. Cubic zirconia is made of zirconium dioxide which creates a softer material. You can also test it out by checking the weight. A diamond and a cubic zirconia can be the same in actual size, but a diamond, being much denser, will naturally weigh more.

Cost

The final red flag that something isn’t right is the price. While diamonds come in varying prices due to the size or other factors determining the quality of a jewel, they will almost always cost more than a cubic zirconia. If a piece of diamond jewelry seems too low for what you are getting, ask to see the certificates to ensure it is a real diamond and not a fake stone or synthetic being passed as the real thing. While the biggest difference between diamonds and cubic zirconia is often the price, you should use your common sense. For example, a small diamond may cost less than a large cubic zirconia stone. Of course, the biggest way to avoid any pitfalls is to shop with a reputable dealer. When you build a relationship with a jeweler that has a strong reputation, you can feel more confident about the diamonds you are adding to your collection.
