When it comes to choosing a diamond alternative, lab-diamonds and cubic zirconia are two popular options. While both offer an affordable alternative to natural diamonds, they have distinct differences in terms of their composition, appearance, durability, and value. In this article, we will explore the key differences between lab-diamonds and cubic zirconia to help you make an informed decision.
Composition
Lab-Diamonds:
- Lab-diamonds, also known as synthetic or man-made diamonds, are created in a laboratory using advanced technology.
- They have the same chemical composition as natural diamonds, which is pure carbon arranged in a crystal lattice structure.
- Lab-diamonds are grown under controlled conditions that mimic the natural process of diamond formation.
Cubic Zirconia:
- Cubic zirconia (CZ) is a synthesized crystalline material made from zirconium dioxide.
- Unlike lab-diamonds and natural diamonds, cubic zirconia is not made of carbon.
- CZ is created by melting powdered zirconium dioxide with other stabilizing elements at extremely high temperatures.
Appearance
Lab-Diamonds:
- Lab-diamonds possess the same optical properties as natural diamonds, including brilliance, fire, and scintillation.
- They have a similar appearance to natural diamonds and can even be indistinguishable to the naked eye.
- Lab-diamonds come in various shapes, sizes, and colors just like natural diamonds.
Cubic Zirconia:
- Cubic zirconia has a different visual appearance compared to lab-diamonds and natural diamonds.
- CZ tends to have more fire and flashes of color than natural diamonds due to its higher refractive index.
- However, cubic zirconia lacks the subtle brilliance and sparkle that natural diamonds and lab-diamonds exhibit.
Durability
Lab-Diamonds:
- Lab-diamonds are extremely durable and have a hardness rating of 10 on the Mohs scale, which is the highest possible rating.
- They are resistant to scratches, chips, and cracks, making them suitable for everyday wear.
- Lab-diamonds do not fade or lose their brilliance over time.
Cubic Zirconia:
- Cubic zirconia is less durable than lab-diamonds and natural diamonds.
- With a hardness rating of approximately 8.5 on the Mohs scale, CZ is more prone to scratching and chipping.
- Over time, cubic zirconia may become cloudy or dull due to wear and tear.
Value
Lab-Diamonds:
- Lab-diamonds offer excellent value for money, as they are typically priced significantly lower than natural diamonds.
- Their value is determined by factors such as carat weight, color, clarity, and cut - similar to natural diamonds.
- Lab-diamonds retain their value better than cubic zirconia due to their diamond-like properties.
Cubic Zirconia:
- Cubic zirconia is an affordable diamond alternative and is much cheaper than both natural diamonds and lab-diamonds.
- Its value is primarily based on the quality of the cut and the clarity of the stone.
- However, cubic zirconia does not hold its value well over time and is generally considered a less valuable option.
Conclusion
In summary, lab-diamonds and cubic zirconia are both popular alternatives to natural diamonds. While lab-diamonds closely resemble natural diamonds in composition, appearance, durability, and value, cubic zirconia has its distinct characteristics. When choosing between the two, it ultimately depends on your budget and personal preferences. If you're looking for a long-lasting diamond alternative that closely replicates the beauty of natural diamonds, lab-diamonds might be the ideal choice. On the other hand, if you're seeking an affordable option with a unique sparkle, cubic zirconia could be the perfect fit.
