How to Tell the Difference Between a Diamond and Cubic Zirconia

The first thing you must know is that there is a huge difference between diamonds and cubic zirconias. Diamonds are more expensive and have a higher density than cubic zirconias. The density of cubic zirconias also makes them heavier than diamonds. However, cubic zirconias are much cheaper. For instance, a one carat diamond retails for approximately $10,000. In comparison, a one carat cubic zirconia costs about $20. As you can see, this is a huge difference in price per carat!

Another way to tell the difference between a diamond and cubic zirkonia is by comparing the two stones. Diamonds have sharp facets, while cubic zirconias do not. Cubic zirkonias retain heat, making them cloudy when you breathe on them.

Although diamonds look flawless from a distance, they are not truly flawless. Every diamond has minor imperfections, which become more apparent with age. A cubic zirconia will look much whiter than a diamond. However, a diamond can have microscopic inclusions and slight yellow color.

Another difference between a diamond and cubic zirconium is that a diamond is a natural stone, while a cubic zirconia is a synthetic gem made by man. Diamonds contain carbon, while cubic zirconia is a cubic crystalline form of zirconium dioxide that contains no carbon.

One more way to test a diamond is to place it in a glass of cold water and see if the stone floats. If it floats, it is probably a fake. A real diamond will sink to the bottom of the glass, whereas a cubic zirconia will float to the top.

Another major difference between a diamond and a cubic zirconia is their hardness. Diamonds are 10 on the Mohs hardness scale, while cubic zirconia is eight. This means that diamonds will last for a long time. Meanwhile, cubic zirconias are softer, resulting in less sharp facets. In addition, they will be more likely to have polishing marks on them.

Another major difference between diamonds and cubic zirconia is that diamonds are much more expensive than cubic zirconias. Regardless of whether you prefer cubic zirconias or diamonds, knowing the difference between the two stones will help you choose the right type of stone for your needs. The difference between the two stones may be very minor, but they are significant.
