Methods of detecting precious stones

When buying gemstones, it is very important to know if the gemstone is genuine or counterfeit, you definitely do not want to pay the price of a genuine gemstone and then get a counterfeit gemstone. Recognizing the original pearl, recognizing counterfeit stones

General methods of detecting gemstones

At first glance, you may not be able to tell the difference between a real stone and a variety of counterfeit stones, so you need to do more than just look at the difference.
It is important to know that in counterfeit stones, everything is usually similar to real stone, even in chemical specifications, but the problem is that they are sold as original stones, and this is a scam.

Knowledge of the original pearl, knowledge of stones

That’s why it’s important to be able to distinguish real stone from counterfeit. In most cases, counterfeit stones are artificial gemstones and are worthless compared to the original stones.

In other words, in the laboratory, they have been made as a substitute for the original stone. It is difficult to distinguish them from each other. The artificial stones are made exactly according to the original pattern.
They are made of plastic and you will find that they are not stones. In fact, they are artificial specimens that may deceive you.

The opinion of a person is sufficient.

I made it a lot, how much is it? I want to use it in Nabrien. As a matter of time, it was established by Dar Azim, it was called by Meishond. As for this, it is realistic.

Possibly, Roche is an old person, diagnosing the original sources of volatility, as well as constructed. For example, Ann Ra, Zaban, is a decisive decision, and Ann Rah is in Dasht Dandan.

The facts are realistic, a sense of humor, Shane Manand, finding Meikand, without a reality, is about the gender of Histend. As for its growth, it is volatile, we want to see it. As for the name of it, it will be a matter of decree. We will give you the opinion of Nakhshid Nakhen Dast Khoud Ra. O my heart.

General methods of detecting gemstones

Diamonds

There are many ways to distinguish genuine diamonds from counterfeits. The main test is to see if they can cut the glass or not. A real diamond can easily cut glass, but a counterfeit sample can’t. There are other ways.

One way to test the originality of a diamond is to put your mouth on the diamond and give it your warm breath (so to speak). If the steam on it disappears quickly, it turns out that the diamond is the original. It can quickly dissipate the heat of your breath, but a counterfeit diamond can hold this vapor for several seconds, and if you rub it on them several times in a row, your breath will condense on its surface and not disappear.

If the diamond you are looking for does not work on the ring or earrings, you can pay attention to the reflection of light on it to determine its originality. Diamonds reflect the light shining on them.

That’s why they look great. It’s hard to use this feature to tell if diamonds are counterfeit, because that’s one of the physical characteristics of rocks.

One way to test this is to use a newspaper to pick up a piece of newspaper and wrap it in newspaper. If you’ve been able to read the newspaper text from a stone or even recognize the darkness of the print, it’s probably a fake stone. A real diamond diverts the light and you can’t see the text.

Ruby

Another gemstone is ruby. Fortunately, there are many ways to tell if ruby is genuine. One way is to pay attention to the color of the stone

Ruby should be bright red. Fake rubies are darker. If the stone is dark, don’t immediately conclude that it is counterfeit. It may be original, but it is not ruby. Lal is also a type of gemstone that is similar to ruby but is slightly darker instead of bright red.

Another way is to hold the ruby between two fingers and then rub it with a nail or coin. If the scratch is probably fake, the rubies are known to be hard and durable, so they should not be scratched.

Sapphire

In fact, sapphires are hard to find after diamonds. And you can easily do the same tests you did on rubies.

In terms of color, the actual sapphire is dark blue, and when you move it under the light, it should not reflect any other light and should reflect exactly the same original light. Counterfeit sapphires are usually brighter and brighter than the original.

You can also look for scratches on the surface of the stone because this stone is very strong. It should not be scratched. If there is a hole or scratch on it, it is probably counterfeit.

Another way you can distinguish the original sapphire from the counterfeit is to look for defects on its surface, this is different from scratching. The real sapphire should not be completely flawless, it should also have disadvantages because it is made in nature. If you don’t see any fault, it may be a counterfeit stone.

Emerald green

It can be said that it is a bit difficult to determine whether the emerald is original or not. On the surface of this stone, if it is original, defects and defects can be seen, so look for uneven surfaces, cavities, and scratches on it.

Color can also help. Most people think that the best emeralds are extracted from Colombian mines.

There are many valuable emeralds on the market, but they can be found in other mines, such as Zambia, Brazil and Afghanistan. It is important to know that emeralds from Colombia are different from other green emeralds.

Colombian stones are green-blue in color and have a yellowish-green halo, and their color is quite different from counterfeit emeralds, which are completely green in color. If the emerald in question is light green, it is probably counterfeit.

Jade stone

Because jade, like the other stones mentioned, is not expensive, they are made in laboratories and are beautiful stones. The stone comes in a variety of colors, green, white, orange, and looks like a gemstone.

A quick way to tell if it’s genuine is to find out which country the stone belongs to. There are two types of real jade stones. One is the Jadeite model, which belongs to Myanmar. The other is the nephrite found in Colombia. It is also mined in Taiwan, Australia and the United States.

If you don’t know where the stone is extracted, there are other ways to determine if the stone is the original or not. One way is to check the density of the stone.

Jade stone has a high density and is usually heavier than it looks. There are several ways to calculate the density of a stone. One way is to mix the two stones. If it sounds plastic, they are probably counterfeit. They are real. Another way to check the density is to lift the stone in the air. If it looks heavier than other stones of the same size, it’s probably the original.

The last method is to test its strength. Like other stones, jade is very strong and must be able to draw a line on the surface of glass and metal.

Amethyst

Another popular stone is amethyst. Usually, these stones are not counterfeit because they are not expensive. However, there may be counterfeit samples on the market. If you want to buy this stone, you must be able to identify the original counterfeit sample. Like a pearl, you can tell by holding an amethyst. Is it the original stone or not?

Make sure it is not in anyone else’s hands before you touch the stone. When you hold it in your hand, keep it cool and feel it for a few seconds until it warms up. If it’s hot as soon as you hold it in your hand, it’s probably counterfeit. Another way is to test for its hardness.

Another way is to try to line the glass with a stone. If you want to draw a line on the glass with amethyst, there will be a white mark.

Seven ways to distinguish between precious and semi-precious stones

Gemstones and precious gems have a diverse and beautiful world, and this diversity sometimes causes problems in distinguishing these stones from each other and how to use them. Even kings and nobles sometimes struggled with these problems to such an extent that some risked their lives to prove their accuracy and honesty in recognizing a stone. Ruby is one of the most precious stones that jewelers and collectors have always had trouble recognizing.

Birthday Stone Cycle

1. For many years, there have been methods for visually detecting stones, but the important thing is that we must first make sure that the stone we have is a piece of gemstone and is different from mineral stones and glass. If this stone is hard and sandy, we should not consider it a precious stone. Also, if the softness of the stone is such that its shape and form can be changed with a simple tool such as a hammer and pliers, surely this piece of stone cannot be a price. Gemstones are usually known for their crystalline shape and can only be changed by abrasives and cutting machines. Even pearls, which are widely used in the jewelry industry, are not considered gemstones. Even the trunk of a fossilized tree cannot be considered a gemstone despite its brilliance, color, and beautiful lines on its surface.

2- The second and, of course, the most important way to identify precious stones is to pay attention to their hardness. Recognizing the hardness of a stone may not lead to an accurate diagnosis of the type of stone, but in any case it helps a lot to include the stone in the list of possible stones. To accurately estimate the hardness of rocks, special tools must be used that use diamonds. The possibility of scratches on the stone after the test makes it possible to use special glass instead of diamonds, which reduces the accuracy of your device, and to ensure this hardness test must be repeated several times.

3- The next step is to pay attention to whether the crystals of your crystalline stone are easily separated from it at any angle. Different rocks in this feature also differ from each other and it is not easy to separate the stone crystals from it. Stones such as quartz and mica can be easily identified in the same way, but if you are worried about damage to your gemstone, you can skip this step.

4 – Another interesting way to identify gemstones is to create a colored scratch on a ceramic surface, the color of which will indicate the type of our stone. By referring to scientific tables and comparing the colored lines of different stones, you can clean your stone from other stones.

5. The crystalline shape of the rocks can also be a good visual indicator for stone detection. Using the world’s most up-to-date experience and knowledge is very important in this part of your experiment. The shape of the atoms and molecules of each stone causes the stones to have their own unique shapes, making them different from other stones.

6. The color of each stone is one of the first signs of visual recognition of any stone, but we must note that color can not be a reliable criterion for diagnosis. For example, rubies can be found in a variety of color ranges, and this variety of colors can confuse pink, green, or yellow rubies with other gemstones. There are even colorless crystal stones that are very similar to diamonds and may mislead us in our diagnosis.

The Chinese are heavily crystallizing and simulating, and they have completely attacked the most important part of the diagnosis, the eye diagnosis. The creation of non-homogeneous impurities and mixed and scattered colors indicates that it will soon be much more difficult to diagnose. But on the other hand, we have to keep in mind that the technology of making artificial stones can never affect the results of accurate tests. On the other hand, laboratory equipment is becoming more accurate day by day.

7- Today, one of the most basic methods of stone detection is the use of professional stone testing equipment. The discovery of various minerals and the similarity of the appearance of some stones after cutting, creates various problems in the evaluation of precious stones, the advancement of science and technology in the field of growth of crystals quite similar to natural minerals and the invention of various methods to improve natural gems. In general, the word petrology was coined in 1891 by Pinker Ton. The name is derived from the Greek words petra meaning stone and logos meaning discussion.
