Real vs Lab Created Gemstones:
What is the difference between Real, Lab Created, Russian Formula Cubic Zirconia and Simulated Gemstones?
 
Real or Natural Gemstones:
Real gemstones are just that, real and natural, as they were created in nature. Natural gemstones may be treated by various methods to make the color appear as we would expect them to look. Some treatments are permanent and some are not. For an example of gemstone treatment, Tanzanite in its natural state is a brownish color, but when heat treated, Tanzanite becomes the beautiful blue-purple gemstone that we admire. Due to the rarity of Tanzanite, all offerings of this gemstone whether in sterling silver rings, lockets, sterling silver bracelets, or earrings by Glittering Treasures are Russian formula cubic zirconia. These are the finest man made gemstones of this type available on the market today.
 
Lab Created Gemstones:
Lab created gemstones are made of the same mineral composition as natural gemstones, and are created in laboratories with equipment that simulates the high pressures and heat that nature used to create the real gemstones far beneath the surface of the earth. A lab created gemstone is identical to the natural gemstone it replicates in color, hardness, composition, luster, and looks.
The only difference between a lab created gemstone and a natural gemstone is that the natural gemstone most likely has flaws called inclusions, and lab created gemstones have no inclusions, as the mineral composition, heat, and pressure are controlled in the laboratory.
The flaws or inclusions in natural gemstones are caused by minute traces of minerals that are trapped within the gemstone during crystallization, and are the result of certain extraneous gases and other minerals being mixed in the molten mass prior to its cooling and crystallization. Natural gemstones with fewer inclusions are given a higher clarity rating, and thus a higher value when being appraised.
It seems odd that when comparing the price of a lab created gemstone which is flawless, against a natural gemstone which has inclusions, that we would knowingly pay for a natural gemstone, many multiples of the price of an identical flawless lab created gemstone, but this is a result of our culture, and the jewelry industries marketing efforts. In today’s marketplace there are many variables that urge consumers to choose jewelry made with stones other than diamonds or natural gemstones. Remember a lab created gemstone is identical to a natural gemstone, except that the lab created gemstone is flawless. Because of the high price of natural gemstones many gemstones sold today are lab created and just as beautiful and long lasting as their natural counterparts.
Sapphires and Rubies are in the Corundum family of gemstones, and are fairly easily created in the laboratory, therefore lab created Rubies and Sapphires are very common. Emeralds and Aquamarines in the Beryl family of gemstones, and Emeralds and Aquamarines are not easily made in the laboratory. Lab created Emeralds are very expensive to make and not as readily found in jewelry. Lab created Aquamarines are not as expensive to make as Emeralds. This is why Aquamarines are commonly made into jewelry.
 
Simulated Gemstones:
Simulated gemstones are created in a laboratory environment, but they differ from natural gemstones and lab created gemstones in many significant ways, and are only made to look like a natural gemstone. Simulated gemstones in most cases do not have the same mineral composition, color, hardness, luster or looks of a natural gemstone or lab created gemstone.
Russian Formula Cubic Zirconia Gemstones: Of the five classes of cubic zirconia, Russian Formula are the finest as they never lose brilliance or color. Of the five major classes, Russian Formula CZ stones have set the world standard for brilliance, cut, and clarity for the past four decades.
Colored cubic zirconia stones: From time to time we receive questions about the varied shades of our Russian formula cubic zirconia stones. What many people do not realize is that the very finest cubic zirconia stones—just like natural gemstones—come in varying shades.
Natural stones can have many different shades from darker to lighter. In fact, all natural stones except perfect blue-white diamonds have these variations.
Cubic zirconia stones too, have these variations due to the highly sophisticated process of vacuum induction used to create them. In this process, a large free form piece of cubic zirconia is created as the various ingredients in cubic zirconia are added into a vacuum.
For stones other than diamond cubic zirconia (e.g., ruby, sapphire, emerald, peridot, or tanzanite) permanent coloring is added at this stage, meaning the color is found throughout the stone, not just on the surface. Many lower quality cubic zirconia stones only have a coloring on the surface which means that they will lose their brilliance over time, but Glittering Treasures uses only the highest quality class of cubic zirconia stones...Russian formula.
 
Different renderings of cubic zirconia stones have slightly different shades, and cubic zirconia stones cut from different locations on the newly created free form cubic zirconia will have slightly different shades.
 
Typically larger stones are cut from the center of the free form and smaller stones from the extremities, making the larger stones a deeper, darker color and the smaller stones with lighter variations. Regardless of the cut, the cubic zirconia stone you get will have a beautiful, realistic ruby, sapphire, emerald, tanzanite, or peridot appearance with its own unique shade.
Glittering Treasures offers some simulated gemstones and crystal gemstones but each is clearly stated in the write up of the piece. Most gemstones found in our sterling silver rings, women and men’s birthstone rings, gemstone rings, bracelets, pendants, and earrings are either natural, laboratory created gemstones or Russian formula cubic zirconia stones. Each item, regardless of the makeup of the stone is 100% customer satisfaction guaranteed. You may be assured that you can shop with confidence at Glittering Treasures.
