difference between cubic zirconia and lab grown diamonds

Cubic zirconia and lab grown diamonds may look similar, but they differ in composition, cost, durability, and sparkle. Here’s a brief comparison:

Composition:

  • Lab-grown diamonds are made of pure carbon, created in a lab using a process that mimics the intense pressure and heat needed to form natural diamonds. They are chemically, physically, and optically identical to mined diamonds.
  • Cubic zirconia is the crystalline form of zirconium dioxide and does not have the same chemical makeup as diamonds. It’s a synthetic stone that’s visually similar to diamonds but is not a diamond.

Cost:

  • Lab-grown diamonds tend to be less expensive than mined diamonds but are more costly than cubic zirconia due to their diamond composition.
  • Cubic zirconia is a more affordable option, offering the look of a diamond at a fraction of the price.

Durability:

  • Lab-grown diamonds are just as durable as natural diamonds, ranking a 10 on the Mohs scale of hardness.
  • Cubic zirconia is less durable, ranking around 8-8.5 on the Mohs scale, making it more susceptible to scratches over time.

Sparkle:

  • Lab-grown diamonds have the same brilliance and sparkle as natural diamonds because they are identical in structure.
  • Cubic zirconia has a different refractive index and can appear more ‘fiery’ than diamonds, but it may not retain its sparkle as long due to wear and scratches.

Both options provide beautiful alternatives to natural diamonds, with lab-grown diamonds offering an eco-friendly choice that’s nearly indistinguishable from mined diamonds, and cubic zirconia providing a cost-effective way to achieve a similar aesthetic.
