Difference between diamond and cubic zirkonia.

As it was sung in one pop song: "The best friends of girls are diamonds." Nothing has been sung about cubic zirconias, but jewelry stores offer a large selection of items with these stones, which have an incomparably low cost, and often look good too. So, diamond and cubic zirconia - is there a difference and what is it?


Any gemologist (that is, a specialist in precious stones) will tell you that a diamond Is a natural mineral that has undergone special processing (namely, a cut diamond). It is characterized by a strong shine. Cubic zirconia is a miracle created by human hands: an artificially synthesized non-precious stone. It is obtained from zirconium dioxide. Therefore, a diamond and its counterpart have a different chemical formula and physical properties. For example, a diamond is harder. It is interesting that they can be confused with a diamond because some physical characteristics of the resulting cubic zirconia are close to those of a diamond. However, there are ways to distinguish between the two pieces of jewelry. So, cubic zirconia is heavier than a diamond, but if we are talking about a small insert or jewelry with an insert, it will be difficult to determine the weight of the stone itself. Jewelers determine the diamond using X-rays, irradiating the stone, since it is the diamond that has the specific property of transmitting rays through itself in large quantities. Of course, a diamond is more expensive, which is why it makes sense to carefully and correctly recognize a cubic zirconia / diamond.

If you want to try your luck and determine on your own by visual signs that there is a diamond or cubic zirconia in front of you, then you can use this advice: cubic zirconia has somewhat rounded edges, which cannot be said about a diamond whose edges are even, straight and pointed.

Conclusions TheDifference.ru

  1. The diamond has a natural, natural origin, and cubic zirconias do not occur in nature, they were obtained in the laboratory
  2. A diamond shines more strongly, and generally has physical and chemical properties different from cubic zirkonia
  3. A diamond is considered a precious stone, but cubic zirconia is not
  4. Cubic zirconia is heavier and has smoother facets than a diamond
  5. A diamond differs from cubic zirconia in that it transmits X-rays in large quantities
  6. The cost of a diamond is much higher than the cost of cubic zirconia.
