Which stone sparkles like a diamond?

Another artificial rival to the diamond.
Moissanite is a stone obtained by mixing silicon with carbon under high temperature.

  • Moissanite is often mistaken for a diamond due to its brilliant shine. Due to its high refractive index, moissanite sparkles approximately 25% more than diamond.
  • The dispersion index, that is, the play of light, is also more than twice as high in moissanite as in diamond.
  • The purity of moissanite is higher – various impurities may be present in the diamond.
  • When exposed to ultraviolet light, a diamond will have a bluish glow, while moissanite may reflect grey, green or yellow. This method is not always justified, since ideal stones do not create this effect.
  • The presence of double refraction, when the light passing through the stone is split into two, indicates that it is moissanite and not a diamond.
  • The price of a diamond increases in proportion to the square of its mass. A 2 carat diamond will cost the same as 4 1 carat diamonds. The price of moissanite for 1 carat is unknown, it all depends on its total weight and color. In most cases, it ranges from 1 to 5% of the cost of large natural diamonds with similar characteristics.

But still, it is practically impossible to distinguish these stones from each other at home.
Technologies for creating artificial materials and growing synthetic analogues of natural stones are progressing. Having the same properties and structure, they cannot be distinguished “by eye” from precious stones. In such cases, to identify a synthetic stone, professional expertise is needed, which is carried out using serious equipment, and the researchers have deep knowledge and skills. Currently, the instrumentation base of the Hematology Center of Moscow State University makes it possible to determine all types of stone refining that are found on the market.
Evaluation of stones is not limited to determining their mass. Diamonds have gradations in color, clarity, and cut quality. Diamonds are assessed according to Russian and international systems.
Independent gemological examination is the only way to protect against counterfeits.
BENDES studio experts described several effective ways to verify the authenticity of diamonds:

It is advisable to use not one of them, but several.

  • When purchasing, you should immediately check for a certificate, which will be the first check of the stone for its authenticity. When issuing a certificate, experts determine its main characteristics: color, clarity, weight, cut quality. To check the certificate itself, its number must be entered on the official website of the company that issued it. We wrote more about the certificate and performance requirements in the article How to distinguish a genuine GIA certificate from a fake?
  • For diamonds, it is important that real, not exaggerated color and clarity characteristics are indicated. For each diamond, the seller must have an appropriate certificate and an expert opinion. In the expert opinion, you need to pay attention to the weight, size, type of stone (natural or refined), a diagram of internal and external characteristics, expert signatures, laboratory details and contacts, and a counterfeit-proof hologram of the form. The number and date of issue are confirmed on the laboratory website.
  • When purchasing a product, you need to find out the number of faces in the stone. The classic diamond cut has 57 facets. If the number of faces is smaller, then the glow and refraction deteriorate. Small diamonds of this cut are inferior to cubic zirconia.
  • The quality of the cut is determined using complex measurements and tables. The buyer can define it as follows: the cut is bad if the stone does not shine.
  • When you hold the stone in your hand, it will not immediately heat up, but will remain cool at first.

To distinguish a stone at home:

  • Test with a glass of water: if you throw a gem into water, it will immediately sink to the bottom. The glass imitation will float on the surface.
  • Temperature contrast: the stone should be heated over an open fire for 30 seconds, then sharply lowered into a glass of ice water. After cleaning a diamond, you will not find a single change. Any other mineral, including imitation diamond, will turn into crumbs, crack, or other defects will occur.
  • Drawing experiment: draw a line or a cross on a piece of paper with a pen and place a stone on it. If the design is visible through the stone, it is not a diamond. But it should be noted that moissanite will pass the test.
  • If you have a 10x magnifying glass handy, you can look at the inclusions. If the inclusion resembles a fine hair or a long thin scratch, it is not a diamond, but moissanite or cubic zirconia. Possible inclusions of diamonds are described in the article

Diamond, being the hardest gemstone, confidently holds the championship in the Mohs mineralogical hardness scale.

Despite its significant cost, a diamond has always been a desirable acquisition for every woman. Unscrupulous sellers still do not neglect this circumstance, actively offering counterfeit gemstones on the market. That is why every potential buyer should know how to distinguish a real diamond from a doublet.

  2. Effective Ways to Verify the Authenticity of Diamonds

The advent of diamond substitutes such as cubic zirconia and satéur have made it increasingly difficult to justify spending large sums of money on traditional diamonds. To the naked eye, these gemstones appear almost identical to real diamonds. Thus, there is considerable debate about the differences between cubic zirconia and diamonds, and whether you should choose one over the other. While moissanite, lab-grown diamonds, and Satéur are some of the most popular diamond alternatives, this article will focus on the comparison between diamonds and cubic zirconia (CZ).

Cubic Zirconia vs Diamonds – What You Should Know

There are two types of diamonds: natural and man-made. In terms of appearance and composition, they are similar. Natural diamonds are mined from the earth’s reserves, while man-made diamonds are produced in a laboratory. These two types of diamond are similar in many ways. However, natural diamonds are expensive due to their natural origin and rarity. A lab-made diamond is cheaper and more accessible on the jewelry market.

Cubic zirconia looks like a diamond, but it is not. It is completely made in a laboratory and has little in common with a diamond, except that it looks like one from afar. While diamonds are made of carbon, cubic zirconia is made of zirconium oxide. The debate between cubic zirconia and diamond will never end as both gemstones have their own advantages and disadvantages.

Satéur Gems® are the closest thing to a diamond and Ultimate Satéur Gems® pass the diamond test without any problems. As far as we can tell, this is the closest stone to a diamond.

The good thing about cubic zirconia is that it is made in a lab and does not have the history of conflicts, ethical issues, and sustainability issues like natural diamond, which often has some questionable history.

Cubic Zirconia vs Diamonds – Durability

Diamonds are more durable than zirconium in terms of strength. On the Mohs hardness scale, diamond is rated 10, while cubic zirconia is rated 8.0 to 8.5. This means that diamonds are durable and can be worn regularly without the risk of damage, chipping, or scratching compared to cubic zirconia. Diamond requires less maintenance, but cubic zirconia needs to be polished more often to maintain its shine. When durability is what you’re looking for, a diamond will offer you more in the long run. At this stage, the determining factor should be the price of the cubic zirconia or diamond.

Cubic Zirconia vs Diamonds – Color

When it comes to color, the fact that cubic zirconia is made in a laboratory means that its color can be adjusted as desired. On the other hand, diamond occurs more naturally, so colorless diamonds are not as easy to obtain. Such colored stones are rare and expensive. For diamonds, they are graded on a color scale from D (colorless) to A (yellow).

This doesn’t mean that there isn’t colored cubic zirconia, you will find that it is just as affordable as colorless ones. A colored diamond is more expensive than a colorless or off-white diamond.

Satéur Gemstones® are colorless and look just like diamond to the naked eye. This stone looks exactly like a diamond without being expensive.

Cubic Zirconia vs Diamonds – Purity

When purchasing a colorless diamond, clarity is the deciding factor that directly affects the cost of the stone. Diamonds come in varying degrees of clarity, from flawless to included.

For diamonds, clarity is the main determining factor in setting the price. Definitely, flawless diamonds are more expensive than diamonds with inclusions. Cubic zirconia is made in a laboratory, so it is impeccable in terms of purity. This is the main difference between cubic zirconia and diamond that buyers should be aware of.

Cubic Zirconium vs Diamond – Dispersion

When a gemstone is said to have fire, it refers to its ability to scatter light into different colors of the rainbow. This dispersion makes the stone sparkle with fire. Diamonds have always been prized for their ability to brilliantly refract light thanks to their dispersion coefficient of 0.044.

Cubic zirconia has a higher dispersion index of 0.066. This causes cubic zirconia to have a tell-tale “rainbow effect” dispersion when light shines on it. This fact is another difference between cubic zirconia and diamond, although it is less noticeable when the two stones are smaller. The difference is more pronounced in larger stones.

Some jewelry lovers don’t like the flash of color that cubic zirconia and other diamond alternatives exhibit when caught in the light. Not everyone likes the vibrancy of colors that these gemstones exhibit. Smaller stones have a less brilliant shine and should be considered in this case.

Cubic Zirconia vs Diamonds – Refractive Index (RI)

When it comes to cubic zirconia versus diamond, the difference in their refractive index is due to the angle at which light hits either gemstone. When light bends and reflects, it sparkles differently in the gemstone. Cubic zirconia has a brighter luster while diamond has a brighter white luster.

Cubic zirconia has a refractive index of 2.15-2.18, while diamond has a higher refractive index of 2.42. Diamond retains more light than cubic zirconia. The only diamond substitute gemstone that comes close to this is a diamond. Satéur Gems®.

Cubic Zirconia vs Diamonds – Density

Cubic zirconia has a higher density than diamonds, making it on average heavier than diamonds. Comparing cubic zirconia to a diamond of the same size will show that cubic zirconia is heavier.

Cubic Zirconia vs Diamonds – Value

The advantage of buying cubic zirconia is that it costs much less than diamond. This is the most affordable gemstone alternative to diamond. When it comes to cubic zirconia compared to the price of a diamond, you will find that the former will be inexpensive.

A flawless 2 carat D color diamond typically costs around $50,000, while a 2 carat cubic zirconia will only set you back $50!

Many jewelry buyers have wondered if cubic zirconia really has any value other than it looks beautiful and diamond-like.

In truth, in terms of financial and investment value, cubic zirconia is simply worthless. It has no second-hand market value and should not be considered an investment in any way.

On the other hand, a diamond is a valuable stone that can be considered an investment (although whether a diamond is an investment is debatable). It can be passed down from generation to generation as a family heirloom and can truly last forever.


So which one should you choose when considering cubic zirconia or diamond?

The class, elegance and prestige of diamonds is undeniable due to their natural beauty, unique characteristics and, of course, impressive marketing tactics. If you have the means, a diamond is certainly an attractive choice.

However, Satéur offers products that give off the same shine, but at a fraction of the price.
