Is a Lab-Grown Diamond a Cubic Zirconia?
When exploring the dazzling world of diamonds, many shoppers wonder, "Is a lab-grown diamond a cubic zirconia?" The answer is a resounding NO! Did I say No? I mean't NOOOOOOOOO! These two popular diamond alternatives differ vastly in composition, durability, and value, making each unique in its own way.
Understanding Lab-Grown Diamonds
Lab-grown diamonds are real diamonds created in controlled laboratory settings using cutting-edge technology. They share the same chemical composition—pure carbon—and physical properties as mined diamonds, including their unmatched hardness and stunning brilliance. Whether you prefer a princess cut or a classic round brilliant, lab-grown diamonds deliver unparalleled elegance.
Cubic Zirconia: A Dazzling Look-Alike
On the other hand, cubic zirconia (CZ) is a synthetic gemstone made from zirconium dioxide. Known for its flawless clarity and affordability, CZ mimics the appearance of diamonds but lacks their chemical and physical characteristics. While a CZ may sparkle brilliantly, it tends to have a more noticeable "rainbow effect" under light, unlike the subtle sparkle of a diamond.
Key Differences Between Lab-Grown Diamonds and Cubic Zirconia
1. Composition: Lab-grown diamonds are made of carbon, while cubic zirconia is composed of zirconium dioxide.
2. Durability: With a hardness of 10 on the Mohs scale, lab-grown diamonds are scratch-resistant. In contrast, CZ rates at 8–8.5, making it more susceptible to wear over time.
3. Weight: Cubic zirconia is denser, meaning it feels heavier than a diamond of the same size.
4. Value: Lab-grown diamonds retain resale value, while CZ is primarily valued for its initial affordability.
Choosing the Right Option for You
When deciding between lab-grown diamonds and cubic zirconia, consider your preferences and needs. If you're looking for a durable, investment-worthy gem, a lab-grown diamond is ideal. However, if affordability and temporary sparkle are your priorities, CZ offers excellent value for its cost. Robinson's does not offer CZ as they are not up to our standards of excellence.
