Are Cubic Zirconia Real Diamonds? Understanding the Differences
If you're in the market for a diamond-like gemstone but don't want to break the bank, you may have come across cubic zirconia. While cubic zirconia is often marketed as a "diamond substitute" or "simulant," it's important to understand that it's not the same as a real diamond. In this article, we'll explore the key differences between cubic zirconia and diamonds so you can make an informed decision when shopping for jewelry.
Composition and Hardness
Diamonds are formed from pure carbon that has been compressed under intense pressure and heat deep within the earth's mantle. Cubic zirconia, on the other hand, is a synthesized material made from zirconium oxide. While diamonds are the hardest substance on earth with a rating of 10 on the Mohs hardness scale, cubic zirconia ranks at 8.5, making it less durable and more prone to scratches and abrasions.
Appearance
To the untrained eye, cubic zirconia may look very similar to diamonds. However, there are a few key differences to look out for. Cubic zirconia tends to have more "fire," or rainbow-colored flashes, due to its higher refractive index. It also lacks the inclusions and natural imperfections that are often present in diamonds, which can actually enhance a diamond's beauty and character. In terms of color, diamonds can come in a wide range of hues, from colorless to yellow, brown, pink, and beyond. Cubic zirconia, on the other hand, is often colorless or close to it, though it can be artificially colored.
Value and Affordability
One of the most significant differences between diamonds and cubic zirconia is the price. Diamonds are among the rarest and most valuable gemstones in the world, and their price reflects that. Cubic zirconia, on the other hand, is relatively abundant and can be synthesized in a lab, which makes it much more affordable. While diamonds can be a significant investment, cubic zirconia is an attractive option for those who want a diamond-like look without the high price tag.
Ethical Concerns
Another important factor to consider when choosing between diamonds and cubic zirconia is ethics. The diamond industry has a controversial history of exploitation, environmental damage, and conflict. While steps have been taken in recent years to address these issues, it's important to research the source of any diamonds you purchase and ensure they come from ethical and sustainable sources. Cubic zirconia, being a synthesized material, does not have these same concerns.
In conclusion, while cubic zirconia is not a "real" diamond, it can be an excellent choice for those who want the look of a diamond without the high cost. Understanding the differences between cubic zirconia and diamonds, including their composition, appearance, value, and ethical concerns, can help you make an informed decision when shopping for jewelry.
