Understanding the machine cut ones

Again, since they are cheaper, more manufacturers use them to make reasonably priced kinds of jewels. You will have the gems set in silver and gold-filled jewels. They are the most popular stones you will find in the market. This is also because they are easier to make and less costly than the 5A one.


These here are at the top of the list when it comes to the cubic zirconia. Notice that the best stone cutters only make such stone cuts. Also, you will have the jewels shining just as much as the diamonds do.

When you are looking for high-quality options, though, you can buy these at an affordable rate. If you want the pieces that will set the same mounting you get with the diamonds, then this is what you need.

Even though they are of excellent quality, you should know that they may not make the best engagement rings. However, if you are considering using it because of the funds, just keep checking to find the one that looks gorgeous.

Whats the difference between A AA AAA AAAA AAAAA?

But how do they set the grades?

Globally when you are rating the cubic zirconia, you can expect the following Cs to match the requirements.


If you are familiar with the gemstone, you will notice one thing to be accurate; they are the same as the diamond cuts. Notice that you will have different shapes, but your cutter’s creativity is the one that makes it stylish and worth it. The cutter will either make it look best or just simple, depending on his or her experience.

Notice that each stone has a personality trait. It’s vital to evaluate the gem, thus giving it a unique personality. So the cutter then works to showcase or bring out the best personality. You can expect the round shape, which is the standard style of jewel.

The square cut is another one of the most common choices. Other people refer to it as princess cuts.

Trillian cuts are another one of the most common types, which is also the triangular cut.

The heart shape is also another one of the common types.

So they may have the same cuts as the diamonds. This also means that they will sometimes sparkle even better than the diamond does.


When you are buying the diamond, they sell it to you as per the carat weight. Well, you will buy it based on the carat size or its weight for the CZ. You will have its rate also depending on the weight. Of course, this is not the main factor as it doesn’t influence the price as much.


Cubic Zirconia comes in a colorless look, but the manufacturers will always add some trace elements to give it other beautiful looking colors. The person rating it will then look at the uniformity and the intensity of the color.

You see, when you are making CZ, the scientist must make sure the place you are molding it on doesn’t influence the color. If it’s not very clear, then the price will be lower. This is the same as diamond because the clearer the diamond, the higher the rate.

Remember, you will always find the white stones, too, for the CZ. Nonetheless, if you like, you can go for the pink one that rates much higher, just like the pink diamond does.  You will also get other different colors you may need, from lavender to red to blue, among others.


Remember to check the clarity of the cubic zirconia further.

It would help if you didn’t use the cubic zirconia that has cloudiness as well as vagueness. This, unfortunately, will make it virtually imperfect. Notice, though, that the CZ should be shiny and clean, thus enhancing the sparkle. In this case, a new gem comes with the highest level of clarity; it almost looks unnatural.

Should I use the grades to guide me?
