You should also look at the color of the light as it enters and escapes the surface of the stone. If you turn both a diamond and a CZ upside down, the bottom of a diamond will give off the entire rainbow of color reflections, whereas CZs usually have more exclusively orange and blue flashes. This is because cubic zirconias and diamonds have different refractive indexes.

A cubic zirconia is a real cubic zirconia, but it is not a real diamond. However, there are a few types of stones that are used as diamond simulants, and cubic zirconia is by far the most common and the most realistic.

In fact, Simon G. engagement rings feature cubic zirconia center stones. By using cubic zirconia, our customers have more control over the shape, style, and cost of their engagement ring. Some of our customers even decide to keep the CZ center stone until a later date, offering them greater budget flexibility.

If a piece of diamond jewelry seems too low for what you are getting, ask to see the certificates to ensure it is a real diamond and not a fake stone or synthetic being passed as the real thing. Of course, the best way to avoid any pitfalls is to shop with a reputable jeweler.

For decades, Simon G. has crafted generational jewelry to be passed down and cherished in your family for many years to come. Using the highest quality precious metals and gemstones, Simon G. has created a legacy in transforming creative concepts into breathtaking pieces.

The best approach for restoring the shine & brilliance of your cubic zirconia rings is largely decided by the setting it has been mounted in & the different gemstones that have been joined in the piece. Soft metals can easily get scratches & gemstones of low density can be forever scarred unless handled properly.

CZ can be cleansed utilizing methods that are acceptable & pretty much similar to cleaning diamonds. Even a good-quality jewelry brush will not scratch the crystals. With this knowledge, you must always pick the best cleaning method for the most delicate material used in the ring.

Utilizing polishing cloths manufactured from soft cotton fabric is deemed one of the least harmful materials for cleaning zirconia rings. Just rub the CZ engagement ring & setting carefully to remove dirt, oils & restore its original sparkle & shine.

Warm water & liquid soap will do wonders for restoring a crisp, clean look to CZ rings. You can wash the jewelry piece with your fingers pretty gently or with a soft cloth. However, do not skip to rinse the ring completely to eliminate all traces of detergent, or your jewelry piece might get a filmy residue that will dull the brilliance of your gem.

These sorts of cleaners are the first choice for most jewelers. These machines carry a water reservoir that cautiously holds the jewelry. At the same time, it is attacked with hundreds or thousands of ultrasonic waves that loosen the debris ambushed within the setting.

Cleansing cubic zirconia rings or CZ Jewelry is an essential part of preserving the brilliance quality of each piece. However, for the jewels themselves, the frequency of the cleansing is actually more significant than how those purifications are carried out.

However, since many Cubic Zirconia jewelry pieces incorporate other gems, it's always a great idea to seek professional cleaning advice from your local jeweler to avoid damaging your pieces. In addition, you can contact professionals at Chic Jewelry & ask for help.

Harold Adamson worked in Hollywood, California, famously creating jingles for Desilu Productions, including the theme for "I Love Lucy." One day, Harold brought his stepson, Lloyd Crisfield, to the studios in hopes of inspiring him to work in the arts! Lloyd, strolling around the Hollywood studios, gazed in awe at the bustling movie sets. He watched the gorgeous stars as they arrived stylishly attired in their designer dresses, accented with glimmering diamonds and pearls. He thought to himself, "Every woman should feel this luxurious!" Understanding the power and emotion of jewelry, Lloyd was inspired in that very moment. In March of 1961, he walked into his stepfather's offices at Desilu and announced,"I am going to create a jewelry brand like no one has seen before!" Without hesitation, CRISLU was born. It was designed for you, your mom, your sister, and every other woman in the world who deserves to experience luxury and opulence. All at an affordable price.

Leave your diamonds in the jewelry box and show off your Crislu jewelry!

Cubic zirconia (abbreviated CZ) is the cubic crystalline form of zirconium dioxide (ZrO2). The synthesized material is hard and usually colorless, but may be made in a variety of different colors. It should not be confused with zircon, which is a zirconium silicate (ZrSiO4). It is sometimes erroneously called cubic zirconium.

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

Cubic zirconia is crystallographically isometric, an important attribute of a would-be diamond simulant. During synthesis zirconium oxide naturally forms monoclinic crystals, which are stable form under normal atmospheric conditions. A stabilizer is required for cubic crystals (taking on the fluorite structure) to form, and remain stable at ordinary temperatures; typically this is either yttrium or calcium oxide, the amount of stabilizer used depending on the many recipes of individual manufacturers. Therefore, the physical and optical properties of synthesized CZ vary, all values being ranges.

Under shortwave UV cubic zirconia typically fluoresces a yellow, greenish yellow or "beige". Under longwave UV the effect is greatly diminished, with a whitish glow sometimes being seen. Colored stones may show a strong, complex rare earth absorption spectrum.

The high melting point of zirconia (2750 C or 4976 F) hinders controlled growth of single crystals. However, stabilization of cubic zirconium oxide had been realized early on, with the synthetic product stabilized zirconia introduced in 1929. Although cubic, it was in the form of a polycrystalline ceramic: it was used as a refractory material, highly resistant to chemical and thermal attack (up to 2540 C or 4604 F).[3]

In 1937, German mineralogists M. V. Stackelberg and K. Chudoba discovered naturally occurring cubic zirconia in the form of microscopic grains included in metamict zircon. This was thought to be a byproduct of the metamictization process, but the two scientists did not think the mineral important enough to give it a formal name. The discovery was confirmed through X-ray diffraction, proving the existence of a natural counterpart to the synthetic product.[4][5]

As with the majority of grown diamond substitutes, the idea of producing single-crystal cubic zirconia arose in the minds of scientists seeking a new and versatile material for use in lasers and other optical applications. Its production eventually exceeded that of earlier synthetics, such as synthetic strontium titanate, synthetic rutile, YAG (yttrium aluminium garnet) and GGG (gadolinium gallium garnet).

Some of the earliest research into controlled single-crystal growth of cubic zirconia occurred in 1960s France, much work being done by Y. Roulin and R. Collongues. This technique involved molten zirconia being contained within a thin shell of still-solid zirconia, with crystal growth from the melt. The process was named cold crucible, an allusion to the system of water cooling used. Though promising, these attempts yielded only small crystals.

Later, Soviet scientists under V. V. Osiko in the Laser Equipment Laboratory at the Lebedev Physical Institute in Moscow perfected the technique, which was then named skull crucible (an allusion either to the shape of the water-cooled container or to the form of crystals sometimes grown). They named the jewel Fianit after the institute's name FIAN (Physical Institute of the Academy of Science), but the name was not used outside of the USSR.[citation needed] This was known at the time as the Institute of Physics at the Russian Academy of Science.[6] Their breakthrough was published in 1973, and commercial production began in 1976.[7] In 1977 cubic zirconia began to be mass-produced in the jewelry marketplace by the Ceres Corporation with crystals stabilized with 94% yttria. Other major producers as of 1993 include Taiwan Crystal Company Ltd, Swarovski and ICT inc.[8][5] By 1980 annual global production had reached 60 million carats (12 tonnes) and continued to increase with production reaching around 400 tonnes per year in 1998.[8]

Currently the primary method of cubic zirconia synthesis employed by producers remains to be through the skull-melting method. This method was patented by Josep F. Wenckus and coworkers in 1997. This is largely due to the process allowing for temperatures of over 3000 degrees to be achieved, lack of contact between crucible and material as well as the freedom to choose any gas atmosphere. Primary downsides to this method include the inability to predict the size of the crystals produced and it is impossible to control the crystallization process through temperature changes.[3][9] 041b061a72
