Another significant difference between diamond and cubic zirconia is their refractive indices. This optical property defines the level of fire, brilliance and scintillation a gemstone exhibits. Cubic zirconia has a much lower refractive index (2.171 – 2.177) than a diamond (2.417 – 2.419), meaning when cut and polished, it does not show
Needless to say, this is another important moissanite vs lab diamond difference. In terms of price, moissanite is one of the more expensive diamond alternatives. A high quality moissanite should cost less than a high quality lab diamonds, but it'll be much more expensive than a white sapphire or cubic zirconia.
If you’re looking for an engagement ring, moissanite is a better choice than cubic zirconia for its durability. However, if it’s other jewelry that you’re looking for with diamond simulants, then cubic zirconia is an acceptable choice. Cubic zirconia has a hardness of 8.5, still a very hard stone.

A: For geeks like our CZ stones quality control team, here are a few physical properties of the cubic zirconia manufactured for use in our finished cubic zirconia jewelry, and sold as loose stones from our website: Mohs Hardness: 8-8.5. Refraction index: 2.17. Density,g/cm: 5.9-6.3.

Moissanite vs. Cubic Zirconia – Value. Compared to diamonds, both moissanite and cubic zirconia are much more affordable. However, moissanite is often much more expensive than cubic zirconia. A high quality moissanite carat can retail for around $400 while a similar sized CZ will cost around $20 to $40.

5A cubic zirconia has a flawless sparkly appearance with a high level of clarity. In contrast, Moissanite is rarely entirely transparent and white. A complicated moissanite process gives this faux diamond flaws and some colored tints. If you prefer clarity in your jewelry pieces, a 5A cubic zirconia is better.

White zirconia is the white form of cubic zirconia, a synthetic stone. A diamond is a natural gemstone, found in deposits. Rough diamonds are cut and polished into the stunning faceted stones that we know and love. Asking what is the difference between white zirconia and diamonds is like asking the difference between genuine leather and faux Additionally, moissanite scores 9.25 on the Mohs hardness scale, making it more durable than cubic zirconia but slightly less durable than diamonds. In summary, diamonds, cubic zirconia, and moissanite are three popular gemstones with unique properties and characteristics. Diamonds are highly prized for their durability, brilliance, and rarity This difference causes different types of brilliance from each stone. Durability: Lab created diamonds have a hardness of 10 on the Mohs hardness scale while cubic zirconia has a hardness of 8-8.5. Color:Like natural diamonds, lab grown diamonds vary in color. 53ihQH.
