Why Your CZ Earrings Look Like Diamonds

There are countless types of earrings and wearing earrings is a personal choice; whether you have one piercing on each ear or five you will want to choose your earrings to match your personal taste. One type of earring that remains popular are cubic zirconia earrings, better known as CZ earrings. CZ earrings are popular for many reasons, the top ones being that CZ can look amazingly close to a diamond; in many cases only a diamond expert would be able to know the difference. Learn what CZ is and what to know if you are thinking about CZ Earrings.

CZ earrings are earrings that are made with cubic zirconia which is a diamond look-a-like. You may be wondering just what cubic zirconia is. It is the crystalline form of a mineral called zirconium dioxide which looks very similar to diamond especially when set jewelry like CZ earrings. This mineral is harder than almost any other gem except for the diamond; it is flawless to the naked human eye and the majority of it is a clear color.

Diamonds are of course very popular but also very expensive. People may not think it is such a great idea to have an engagement ring made of CZ, but CZ earrings are very acceptable and if you purchase a quality pair, they only person who needs to know that you have CZ earrings and not diamond ones, is you.

The history of CZ earrings begins in the year 1892 when the mineral called baddeleyite was discovered. Baddeleyite is the natural form of CZ. Years later in 1899, natural CZ was discovered; at the time the men who made the discovery did not even think that it was important enough to give it a name. Experiments were done in the 1960 by researchers who were trying to discover different melting points and see if they could create crystals. A Russian scientist later worked on different techniques and perfected it enough that he named the gem the Fianit; however it was only used in jewelry in Russia. In the year 1973 the news of this was told to other countries; this lead to production of the CZ gem across the globe beginning in 1976.
Now, the process that is used to make CZ earrings is that zirconium oxide and yttrium oxide are mixed together and then heated; this creates what we know as cubic zirconia. While doing this process, the gems that are created can be as big as five centimeters long; they are then cut into smaller gems that would fit perfectly into CZ earrings. If the crafters choose to make gems of different colors, they do so by adding other elements. They can create colors ranging from yellow to red, pink to brown.

Since 1976 jewelry makers have been seeking ways to make the cubic zirconia look even more like diamonds. One method that they invented is to coat the CZ with what is called a DLC which stands for diamond like carbon. It makes the CZ harder, shinier and look just like a diamond to the human eye. Antoher method which involves spraying an extremely thin layer of gold to the finished CZ gem works just as well. It is because of these methods that CZ earrings appear to be diamond earrings.

Tips that Will Keep your Cubic Zirconia Jewelry Sparkling

Cleaning cubic zirconia (CZ) jewelry is much easier than you think! So take advantage of these simple tips that will keep your precious jewelry sparkling and lustrous—so you can enjoy them for years to come.

Like diamonds, the precious CZ gems need to be cleaned to maintain their original brilliance and luster. Many variables in our surrounding can dull the shine of precious gems: body lotion, perfume, perspiration, hairspray, or just simply, normal everyday wear. All lotions and soap film are some of the more difficult materials to remove. Just a little of any of these materials on your cubic zirconia stone, will take away much of the visual brilliance of the stone. So it is vital to keep your CZ clean to maintain its sparkling diamond look. A convenient way to clean your cubic zirconia jewelry is to use a small brushing device with soft bristles, along with warm to hot water mixed with a mild liquid dishwashing detergent, and brush as well as possible to remove any scum build-up.

Then, rinse well in warm to hot water, pat dry with a clean cloth, and take a look. If more cleaning is needed, soak the jewelry piece in hot water, with about 1/3 detergent to 2/3 hot water. Then, just brush again. When you’re done cleaning your cz jewelry, be sure to dry it well so to keep its brilliant shine.

Avoid exposing your cubic zirconia jewelry to abrasive substances such as household chemicals when cleaning with bleach or ammonia, or when swimming in chlorinated water, as these chemicals can damage your jewelry. Although most abrasive cleansers will not damage a cubic zirconia stone, they will, however, take the lustrous shine off the metal in which the stone is set.

Gemologists can agree that cubic zirconia comes closer than any other gem material to matching the characteristics of a diamond—it’s uncanny. As cubic zirconia is quickly becoming more popular as a desirable substitute for diamond, it’s important to care for it the same way you would a diamond.

So if for some reason you cannot remove the dirt off your cubic zirconia jewelry, take it to a jeweler and give it a high-pressure steam clean, as would be done to a diamond. This will remove almost any scum off your CZ jewelry.

When we clean a customer's jewelry and inspect it for wear, and loose or missing stones, we find the jewelry needing repair is most often a jewelry piece that has never been cleaned by the owner. Persistent dirt gets between the metal settings and the stones, causing abrasive wear and eventually, perhaps a loose stone.

One of the most basic rules of jewelry care is to apply all lotions, make-up, hair spray, etc. first, before you put on your jewelry. To minimize scratches and other damage, store your jewelry either in a cloth pouch or in a separate compartment in your jewelry box.

Now that you know how easy it is to care for your cubic zirconia, be sure to clean your CZ jewelry regularly—depending on how often you wear it; if you wear it everyday, cleaning it once a week is sufficient. Follow our simple tips on cleaning cubic zirconia, and you can be certain your CZ jewelry will not only maintain its original brilliance and luster for years to come, but it will continue to sparkle radiantly for you when you wear it, and show it off!

CZ Introduction

CZ Cubic Zirconia
CZ - Cubic Zirconia - Fianit - ZrO2 - zirconium oxide, a mineral that is extremely rare in nature but is widely synthesized for use as a diamond simulant. The synthesized material is hard, optically flawless and usually colorless, but may be made in a variety of different colors.

Because of its low cost, durability, and close visual likeness to diamond, synthetic cubic zirconia has remained the most gemologically and economically important diamond simulant since 1976. Its main competition as a synthetic gemstone is the more recently cultivated material moissanite.

Cubic Zirconia vs Diamond

Cubic Zirconia Crystals Cubic zirconia is so optically close to diamond that only a trained eye can easily differentiate the two. There are a few key features of Cubic Zirconia which clearly distinguish it from diamond, some observable only under the microscope or loupe.

For example:

- Dispersion. With a dispersive power greater than diamond (0.060 vs. 0.044) the more prismatic fire of Cubic Zirconia can be considered excessive and is a relatively obvious give away to even an untrained eye.

- Hardness. The inferior hardness of Cubic Zirconia (8.5 vs. 10 of diamond) manifests itself in the gem's lower luster, rounded facet edges and surface scratches.

- Flaws. Contemporary production of cubic zirconia is virtually flawless. Whereas most diamonds have some sort of defect, be it a feather, included crystal, or perhaps a remnant of an original crystal face.

- Specific gravity. CZs are heavyweights in comparison to diamonds; a Cubic Zirconia will weigh about 1.7 times more than a diamond of equivalent size. Obviously, this difference is only useful when examining loose stones.

- Index of refraction. Cubic Zirconia has a lower index of refraction than diamond.
* This allows more light to leak out of a Cubic Zirconia, especially when greasy or wet.
* CZ's lower index of refraction causes it to have less luster than diamond.

- Cut. Under close inspection with a loupe, the facet shapes of some CZs appear different from diamonds.
* In theory, many gems (such as CZs and diamonds) look best when the star facet, crown main facets, and upper girdle facets do not quite meet. Diamond has such a high refractive index that having these facets meet at a single point does not cause much loss of fire or reflection. Diamonds normally have these facets meet at a point, because that is more symmetrical and reflects well on the cutter's precision. On the other hand, Cubic Zirconia has a considerably lower refractive index than diamond. CZs are often cut with 6-sided crown main facets, so that the star facets do not touch the upper girdle facets. This optimizes the brilliance and fire of the CZs.
* The optimum angle of the main crown facets is steeper for diamond than for Cubic Zirconia. CZs are often cut so that the crown main facets do not touch the girdle. This allows the CZs to have a shallower crown angle, while still having the same crown height as the diamonds being simulated.

- Thermal conductivity. This is probably the most important property of diamond from a jeweller's perspective: all they need do is apply the tip of a thermal probe to a suspect diamond. CZs are thermal insulators whilst diamonds are among the most efficient thermal conductors, exceeding copper.

- Color. More precisely, the lack of color: Only the rarest of diamonds are truly colorless, most having a tinge of yellow or brown to some extent. By comparison, Cubic Zirconia can be made entirely colorless: equivalent to a perfect "D" on diamond's color grading scale. Furthermore, the fancy colors of Cubic Zirconia in no way approximate the shades of fancy diamonds...
