Types of Man-Made Gemstones

 

Laboratory Created Gemstones used in making jewelry:

Simulated Ruby Jewelry Making ComponentThere are a couple of types of simulated gemstones that are available. Simulated Sapphire Jewelry Making ComponentOne type of simulated gemstone is a laboratory created gemstone, made to be chemically identical to the naturally occurring gemstone.  At right you can view man made ruby gemstones and at left you can see man made sapphire gemstones.  Because these gemstones are made to be chemically identical to the naturally occurring gemstone these man made or laboratory created gemstones are slightly more expensive than the Cubic Zirconia discussed below. 

Cubic Zirconia Gemstones:

The second type of simulated gemstones are made from Cubic Zirconia.  Cubic Zirconia, also called CZ, is a man-made clear crystal, or it can be colored in a variety of different colors.  CZs are made of the chemical zirconium oxide (ZrO2) and can be cut, faceted and polished like all gemstones.  CZs have a very high refractive index which is the property that allows them to reflect a lot of light in a manner similar to a diamond.  The refractive index of CZs is close to the refractive index of diamonds  and for this reason, both CZs and diamonds have that sparkle that makes these stones so special.  The hardness of a CZ is 8.5, which is less than a diamond (hardness of 10) but more than quartz (hardness of 7).  Having a hardness of 8.5 is very important because it means that CZs are durable and impervious to scratches from dust or sand (frequently dust and sand are composed of quartz with a hardness of 7).  The bottom line on CZ's is that they look so similar to diamonds that most jewelers had to have new tests developed that would allow them to test the difference between the two.  Visually, it is practically impossible to view a CZ and determine whether it is a diamond or not.  Upon visual inspection, many jewelers will assume that a flawless, perfect stone with absolutely no inclusions or clouding is a CZ because it is hard to make a perfect diamond in nature, but easier to make a flawless CZ in the lab.  CZs are suitable for every day wear because the only naturally occurring materials that are harder than a CZ are diamonds, sapphires and rubies.  Naturally occurring dust and sand do not include diamonds, rubies or sapphires so dust and sand are not able to scratch a CZ. 

 A round 8mm CZ is the same size as a 2 carat diamond.  Fortunately for us, they don't cost the same.  A round 6mm CZ is the same size as a .84 carat diamond, and a round 4mm CZ is the same size as a 1/4 carat diamond. 

If even a jeweler can't visually tell the difference between a CZ and a diamond, and the CZ is strong enough so that it won't become scratched or dull, isn't it worthy of consideration?  You can view several of the colors of CZs here.

Simulated Ruby Jewelry Making ComponentSimulated Sapphire Jewelry Making ComponentSecurity Warning!

These stones can not be easily distinguished from the real thing.  For this reason, we strongly suggest that they not be worn in an environment where personal safety and security could be an issue.  Remember, given that a pair of 2 carat, flawless, white diamond earrings could cost $10,000 and that our white 2 carat CZs can not be distinguished from a diamond visually, please do not wear these earrings in places where 10,000 temptations might be too hard to resist.  We do not want anyone to get hurt because they were wearing jewelry made from our products. 

Caring for your CZ Jewelry

Now that you've made your CZ jewelry, let's also discuss how you care for your jewelry.  With CZs you care for them the same way you would care for a diamond.  Skin oil and the film from soap can dull the shine of your CZ.  They won't damage the stones, the film will just reduce the shine and sparkle of the stones. The bottom line in caring for your CZs is to keep them clean and free from any oily films.  Clean your CZ with a cleaner that will dry without leaving a film.  Soaps or detergents can be used to clean your CZ, but be sure to wipe the stone dry to remove any soap film.  Ultra-sonic jewelry cleaners can be used with CZs
