Cubic zirconia is made by melting zirconium oxide powder with stabilizers like magnesium and calcium at 4,982ºF. After being removed from hours of heat, crystals form and stabilize. The crystals are then cut and polished. Each lab has its own specific methods for making cubic zirconia.
What is cubic zirconia made out of?
Cubic zirconia is a manmade mineral made of zirconium dioxide. CZs can appear to be very like diamonds, but they have very different mineral structures. Cubic zirconias have been found in nature in small amounts, but the vast majority used in the jewelry are man-made in a lab.
How much is a 1 carat cubic zirconia worth?
Cubic Zirconia: Diamonds Price. Cubic zirconia simulants are much, much cheaper than mined diamond. For example, a flawless 1 carat round colorless diamond graded D costs around $12,000 whereas a 1 carat cubic zirconia is only worth $20.

How much does it cost to make cubic zirconia?
Price. Cubic zirconia is very inexpensive, since it’s synthetic and mass-produced. A cut and polished one carat cubic zirconia stone will cost $20 and a similar two carat stone will cost about $30. This is far cheaper than diamonds, which start at $1800 for one carat and increase considerably as size goes up.
Why are cubic zirconia so expensive?
Because cubic zirconia is made in a lab, it lacks the natural imperfections that diamonds have. A flawless diamond is incredibly rare and, thus, incredibly expensive. While some may regard cubic zirconia as flawless, they’re usually considered “too perfect” or fake-looking.

Remember that cubic zirconia will not last a lifetime with every day wear – for wedding rings, cubic zirconia usually begins to cloud up and scratch in about 2 years.
Should I buy cubic zirconia or diamond?
Although cubic zirconia is still durable, it does not compare to the hardness of a diamond; its rating on the Mohs Scale of Hardness is 8.5. … If you want a stone that shines, a diamond is the best bet. Cubic zirconia has a much lower refractive index than a diamond, so it captures light differently and shines less.
Will cubic zirconia pass a diamond tester?
Can cubic zirconia pass a diamond tester? – Quora. No. CZ does not register any result on a diamond tester. In that regard it is the same as glass.
Is zirconia harder than diamond?
It is a dense substance, with a density between 5.6 and 6.0 g/cm3—about 1.65 times that of diamond. Cubic zirconia is relatively hard, 8–8.5 on the Mohs scale—slightly harder than most semi-precious natural gems. … Its dispersion is very high at 0.058–0.066, exceeding that of diamond (0.044).
Do CZ stones sparkle like diamonds?
When we talk about RI, we are really talking about how light is reflected off the stone. CZ has an RI of 2.15 – 2.18, while a diamond’s RI is higher at 2.42. Although both stones sparkle, a diamond has a greater depth of brilliance which the CZ cannot match. A CZ cannot hold light as a diamond does.
Does a real diamond sparkle rainbow?

How much does 1 carat cubic zirconia weigh?
The carat of any type of gemstone, including man-made gemstones like cubic zirconia, is a measurement of the weight of the stone – not the size of the stone. A 1 carat stone will weigh 0.2 grams, or 200 milligrams, and the 1 carat size for each gemstone will depend on the density of the stone.
How long does it take to make a cubic zirconia?
The time (eight to 10 hours for one carat) required to cut an oval is roughly twice the time needed for cutting a round stone because it takes more time to do the primary shaping. Other testing methods are used to measure optical and physical properties.
How do you make a cubic zirconia shine like a diamond?
A good way to clean your cubic zirconia is to use a small soft brush and hot soapy water to remove dirt. Rinse it in warm water and pat dry with a clean cloth. This will restore the cubic zirconia stone to its natural shine and clarity.
