Cubic Zirconia and diamond are both popular gemstones frequently used in various types of jewelry. Although they may appear similar to the untrained eye, there are some key differences between the two.
Key Takeaways
- Cubic zirconia is a synthetic gemstone made from zirconium dioxide, while diamonds are typically formed naturally from carbon.
- Diamonds are more durable and rare than cubic zirconia, which is less durable and more common.
- Cubic zirconia is generally more lustrous and less expensive than diamonds.
Cubic zirconia is a cubic crystalline substance made of zirconium dioxide, first discovered in 1892. It was later synthesized into a gemstone in 1937 by melting zirconium dioxide and yttrium or calcium oxide together. Since 1976, cubic zirconia has been a prominent and cost-effective alternative to diamonds.
Diamonds, on the other hand, are a natural substance made of carbon that forms under high temperature and pressure conditions in the Earth’s mantle. They are the hardest known substance in nature. While diamonds are primarily formed naturally, synthetic diamonds can also be produced through a high-pressure, high-temperature process.
There are several key differences between cubic zirconia and diamonds. Diamonds are among the most durable substances in nature, while cubic zirconia is less durable. Colorless diamonds are rare, whereas colorless cubic zirconia is relatively common. Diamonds are excellent thermal conductors, while cubic zirconia is a thermal insulator, making it easier for those with the right instruments to distinguish between the two gemstones. Additionally, cubic zirconia is heavier and more lustrous than diamonds, as well as being significantly less expensive.
Despite being considered synthetic imitations of diamonds, cubic zirconia is still highly valued by consumers due to its beautiful and lustrous appearance, as well as its durability. Both cubic zirconia and diamonds are among the best-selling gemstones on the market.
