How To Tell Cubic Zirconia From A Diamond
Diamonds are one of the most popular gemstones in the world. They have a high value and can be worn for any occasion, from casual to formal. Cubic zirconia is also a diamond substitute that has been around since cubic zirconia was first created. It has many similar properties as diamonds, but it is much cheaper than cubic zirconia and does not require as much maintenance to keep looking nice.
This article will discuss how you can spot cubic zirconia from diamonds before you make any big purchases!
What Is Cubic Zirconia?
If you look at cubic zirconia side by side with natural diamonds up close, there will be some apparent differences between them!
The only difference cubic zirconia differs from diamond is that cubic zirconia can be created synthetically, whereas diamonds are naturally occurring minerals found deep below the earth's surface.
Moreover, Cubic Zircons do not sparkle like diamonds because they lack specific diamond properties such as refraction or dispersion (dispersion makes diamonds shine brightly under natural light).
The Differences Between Diamond And Cubic Zirconia
When looking for differences between cubic zirconia and diamonds side by side, there will be some critical differences between cubic zirconia and diamonds.
Cubic zirconias will not sparkle like a diamond because they lack specific properties of genuine diamond, such as refraction or dispersion (dispersion makes diamonds shine brightly under natural light).
Cubic zirconia also lacks the 'fire' seen in diamonds, which is caused by their high purity. Another difference you might notice is that cubic zirconia stones tend to appear more yellow than white even when placed next to each other.
How To Spot The Differences Between A Diamond And Cubic Zirconia
The following tips can help tell a CZ from a real diamond.
- Weight test: If the stone is loose and may be weighed, it's simple to tell if it's a CZ because it will weigh about 1.7 times as much as a diamond of the same dimensions.
- Fog test: If you breathe on a CZ, as you would do to fog a mirror, it will stay hazy for several seconds, while a diamond's fog will dissipate almost immediately. This is because diamonds have greater thermal conductivity than CZs.
- Newsprint test: The stone must be loose for this test. Turn the stone upside down on a newspaper or magazine page. You will not be able to distinguish letters with a diamond because of its high refractivity (it bends light more than CZ), but you will be able to make out sections of the print using a CZ.
More Ways To Find Out If A Diamond Is Real
The following are some other indicators that a stone may be cubic zirconia or another simulant:
- If the setting is made of base metal, gold plated, or silver, it is highly unlikely to include genuine diamonds. The stamp 14K, 18K, or PLAT should clue you into the fact that the setting is made of precious metals. It's not definitive; CZ can be set in any material - but it's a sign.
- If the stone is colorless and has no visible inclusions under a microscope, it's unlikely to be a real diamond. This isn't definitive, since some genuine diamonds are colorless and flawless.
- It is unlikely to be a real diamond if the facet junctions are slightly rounded or the stone has any noticeable scratches when viewed under a magnifier. Diamond's extreme hardness allows it to be faceted into razor-sharp edges, making it highly unlikely to be scratched or scuffed while being worn.
Although taking the stone to a professional jeweler is always the best option, other home testing is feasible. When in doubt, bringing the stone to a qualified expert is usually the best course of action.
The majority of jewelers have easy electronic testers that can quickly determine if a CZ is a substitute. Trained gemologists can do all of the tests necessary to make many important distinctions.
Where To Purchase Real Diamonds
Natural diamonds are the king of gems for a reason. They are rare, exquisite, and valuable. However, raw diamond mining and processing are costly. Therefore, their supply is restricted, resulting in a scarcity that enhances their value.
Therefore, it is essential to buy from a reputable source. This may be a jeweler or, for high-value stones, an independent diamond merchant.
We have diamonds that have been graded by the most renowned gemological institutions, including GIA, IGL, IGI, and AGS. Shop with us today to find the perfect diamond for any occasion!
