Cubic Zirconia vs Lab Diamond: Understanding the Differences
Introduction
There are many debates regarding cubic zirconia vs lab diamonds, and one of them is the discussion for the best gemstone that will perfectly suit your jewelleries. Both are alternatives to the natural diamond, but they do differ in some ways that could change which of the two you would prefer. The differences and benefits and drawbacks for each option will be discussed in this blog to aid your choice.
What is Cubic Zirconia?
Cubic zirconia (CZ) is a synthetic gem with a chemical makeup of zirconium dioxide. It was patented in the 1970s and has since become one of the most impressive diamond substitutes due to its optical impact, very low price, and brilliant fire. CZ is known for its brilliance and fire, while quite often showing more colourful flashes than the natural diamond. However, it's important to clarify that cubic zirconia isn't a diamond; it's a lab-grown material designed for mimicking diamond appearance.
What are Lab Diamonds?
Lab diamonds, which are also called lab-grown diamonds or synthetic diamonds, are formed in a lab environment using cutting-edge technology. They are chemically and physically the same as natural diamonds but consist entirely of carbon. High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD) are the leading processes of producing lab diamonds. Unlike cubic zirconia, lab diamonds are actual diamonds having the same durability and brilliance.
Key Differences Between Cubic Zirconia and Lab Diamonds
1. Chemical Composition
-
Cubic Zirconia:
zirconium dioxide (ZrO2).
-
Lab Diamonds:
pure carbon (C).
2. Hardness and Durability
-
Cubic Zirconia:
Ranks 8-8.5 on the Mohs hardness scale, making it a less efficient glass indicator of scratchability. It can get scratched and may fog over time.
-
Lab Diamonds:
10 in Mohs hardness scale, thus the hardest natural material on earth.
3. Brilliance and Sparkle
-
Cubic Zirconia:
has a higher dispersion rate (0.058-0.066) than diamonds, resulting in intense flashes of colors but not very brilliant.
-
Lab Diamonds:
have lower dispersion (0.044), but provide a traditional diamond sparkle preferred by many.
4. Price
-
Cubic Zirconia:
is far less expensive than lab-grown diamonds, though they are also generally attractive for the money-conscious customers.
-
Lab Diamonds:
are, however, closely priced to mined diamonds and still maintain their competitive difference.
5. Appearance
While both stones resemble each other at first, certain slight differences exist:
-
Cubic Zirconia:
Perfection too clear, without any inclusion or flaw.
-
Lab Diamonds:
May have the tiniest occurrence of tiny inclusions or imperfections that only a gemologist could recognize.
Conclusion
Between cubic zirconia vs lab diamond boils down to individual preferences and values. Cubic zirconia may be the best bet for you in the event that you want a cheaper and brightly shining stone. On the other hand, if you want something that will give you the look and feel very much like the original diamonds, then lab-created diamonds may be better options for you.
Both of which would offer an ethical alternative for mined gemstones and give consumers the freedom to choose what matches their value in sustainable and responsible purchasing. As you consider the final options regarding engagement rings or other fine jewelry pieces, weigh each of these factors carefully to find the perfect stone for your style and budget.
