Diamonds will encounter something that will cause black spots

Hello, what is the clarity of your diamond? SI, P, or VS.

If the SI and P grades, it is normal to see black spots, cracks or something on the surface of the diamond, and natural diamonds will have inclusions (impurities) or cracks (if there is a bare diamond certificate, you can check whether the position marked on the certificate is consistent, if you set it, it means that you have it before you sell it.) If it doesn't match, it may be that you bought it after you bought it, and there are many reasons. The particularly clean ones are VS, VVS, and IF levels.

In another case, diamonds are more oily, so they are easy to stick to dust or other things, you can try to rub it with alcohol to see if the impurities on the surface are still there.

In the last case, it may be a new break by external forces, if it is not the above two situations.

The above is my opinion, I hope it can help you, if you find it helpful, please choose me, I will continue to answer the follow-up questions for you.

Diamond has a hardness of 10, which is the elemental substance of carbon. It has all the chemical properties of carbon element. There is almost no reaction at room temperature, as for how many years to keep it without decay, it depends on how long you want it to keep it, if you protect it well, it will never change, if you burn it, then it will become CO2 in less than 1 second.

Diamond is also the most stable substance in the world, and basically does not react with other substances, especially air, which will cause diamond deterioration and oxidation. But diamonds, like other items, can get soiled or dusty. Various solvents, powders, soaps, and even oils produced by the human body can form a thin film on the surface of the diamond, reducing the diamond's luster.

In addition, there is a lot of dust in the air that can adhere to the surface of the diamond. At the same time, I will introduce you to a good way to clean diamonds: first pour a little wash into a bowl and stir with hot water to foam, then put the diamonds into the bowl, wipe them with a soft brush, after the brushing is finished, take out the diamonds and put them in a metal mesh or tea strainer, rinse them with warm water, and then dry them with a soft cloth.

The presence of black dots in a diamond indicates a flaw.

The clarity of the diamond is mainly the clarity of the diamond, whether there are impurities inside the diamond, and it is generally necessary to observe it through a high-powered microscope to see the nature, size, location, and quantity of internal impurities. The less impurities inside the diamond, the purer the value, and the better the transparency. Diamond clarity.

There are 13 levels, and you can see the level comparison according to the picture above.

That is, a 10x magnifying glass.

How much of the contents of the lower diamond. GIA divides the diamond clarity into FL, IF, VVS1-VVS2, VS1-VS2, SI1-SI2-SI3, I1-I2-I3 and other grades, decreasing from front to back.

When considering the purchase of SI1 grade, this clarity is more cost-effective and looks better, and the naked eye cannot see the internal flaws of the diamond.

The color of diamonds is divided into 23 grades, from D grade high-quality colorless to Z grade pale yellow or brown, the grade is decreasing gradually, and the quality is also decreasing

Colorless level: D, E, F, the types of colorless level are very rare, among which D color is a very good grade color, and it is also the color grade that many diamond rings like to use.

Near-colorless levels: G, H, I, J, almost no colors are visible to the naked eye, but when compared with colorless levels, they will be relatively colorful.

Mild yellowish grade: K, L, M, straight ** is generally difficult to see the color, if it is more than 1 carat diamond, the color will be relatively obvious.

Yellowish grade: N, O, P, colors that can be seen even with the naked eye, few people will choose such a diamond ring.

As for the P-grade and later, it is less likely to appear in the public's field of vision, because the jewelry industry has a very strict control over the color grade of diamonds, and most brand diamond rings use colorless grade diamonds.

It is normal for natural diamonds to have black spots. ScintillationThe scintillation of a diamond is a flash, that is, the reflection and flash of white light on the surface of the diamond, light source, and observer when they move relative to each other. Colorless, transparent, well-crystalline octahedral or curved poly-shaped diamonds that exhibit good sparkle even without cutting.

Dispersion or fireThe various crystal planes of diamond are like prisms, which can decompose the white light that enters the crystal through refraction, reflection and total reflection into the constituent colors of white light - red, orange, yellow, green, blue, indigo, violet and other colors.

Extended Materials. In diamond crystals, carbon atoms are connected to each other in a tetrahedral bond manner to form an infinite three-dimensional skeleton, which is a typical atomic crystal. Each carbon atom forms a covalent bond with four other carbon atoms in a sp3 hybrid orbital to form a tetrahedron.

Since the C-C bond in diamond is very strong, all the valence electrons are involved in the formation of covalent bonds, there are no free electrons, so diamond is not only hard and has an extremely high melting point, but also does not conduct electricity. In industry, diamonds are mainly used to make probes and grinding tools for drilling, and are also used to make high-end ornaments such as hand ornaments, which are very expensive.

A diamond's inclusions refer to all the characteristics that affect a diamond's clarity. Different types of inclusions have different degrees of impact on clarity, and there are two main types: inclusions and external blemishes. Inclusions are imperfections that are within a diamond or reach the surface of the diamond.

It is important to observe inclusions because they are the main factor in determining a diamond's clarity grade.

The types of inclusions are as follows:

Crystal] crystal refers to all mineral crystals with obvious three-dimensional morphology in the diamond, and the crystal can be divided into colorless or light-colored inclusions and dark or black inclusions.

Dots] The smallest visible inclusion inside a diamond looks like a small white dot under 10x magnification.

Cloudy] A hazy or milky inclusion with no clear border in a diamond, which may be made up of many tiny dots, or it may be a cavity. Clouds are often distributed according to the diamond's axis of symmetry (related to the diamond's growth history), and sometimes there are some black dots of varying sizes in the white cloud.

Feather-like fractures caused by cleavage or tension in the diamond. If the pinnae is relatively large, it is called a "crack", and sometimes a semicircle of pinnae can be seen.

Whiskered waist (raw edges, beards).

The whisker-like cracks that exist on the waist are deeply disturbed into the inner part, resembling an old man's beard, and are caused by excessive coarse grinding.

Internal Texture] The growth marks caused by the irregular arrangement of atoms inside the diamond are often flat and straight, and if they are white, colored or reflective, they will affect the clarity.

Twin crystal center] the center point of the dislocation of the dust loss crystal structure, often accompanied by dots. 【Concave crystal plane】

The original crystal plane that recesses into the inside of the diamond from the surface.

Laser holes] Holes left by the use of laser beams and chemicals to remove dark inclusions inside the diamond, resembling white funnels or pipes, can be filled with high refractive index glass.

Wound marks (marks).

The surface of the diamond is struck by an external force into a root-like shape that protrudes into the inside of the diamond.

Summary. Dear, I am happy to answer for you how to solve this problem of black spots visible to the naked eye of diamonds. Kiss and kiss, the solution to the black spots visible to the naked eye of the diamond is that it can be replaced.

Dear, I am glad to answer for you how to solve this problem by digging the black spots visible to the naked eye in the diamond canopy. Kiss and kiss, the solution to the black spots visible to the naked eye of the diamond is to replace the shaku core.

There is only one way.

Kiss, take out your diamond certificate and take a look. Black dots visible to the naked eye. If you go to change it, you will definitely say that what you buy is the ** that ruins the quality of this world. If you don't return to the game, there is also an after-sales exchange, and you can increase the price by 30% for a better one.

Si1 clarity, H color can generally be seen.

Generally not visible.

Unless it is not SI1 clarity, H color.

Summary. Hello, I am happy to answer your question, how to solve the problem of black spots visible to the naked eye of diamonds The answer to your problem is: if the diamond does not have black spots visible to the naked eye when buying, it may be stained with oily black substance in the later stage, and it can be washed with water.

Hello, I am happy to answer your questions, how to solve your problem with black spots visible to the naked eye of diamondsThe answer is: if the diamond does not have black spots visible to the naked eye when buying, then there is early hunger may be stained with oily black substance in the later stage, and you can wash it with water.

However, if there are black spots visible to the naked eye when you do not buy it, it means that there are major flaws in the diamond dowel, indicating that the diamond clarity is very low, basically below the SI, and the general diamond clarity is above the SI, and any flaws in the diamond cannot be visible to the naked eye, and it is possible to find it by relying on a magnifying glass of more than 10 times the distance of the free observer.

The presence of black spots visible to the naked eye of diamonds cannot be solved by any means, because the black spots visible to the flesh are defects, and the clarity of diamonds with the defect of pure silver leakage is generally below the SI grade.

Summary. The black spots visible to the naked eye of the diamond may be caused by dirt on the surface of the diamond, which can be scrubbed with a small amount of soapy water dipped in cotton, then washed with water, and finally dried with a soft cloth to remove the dirt on the surface of the diamond. If the black spots persist, try applying an alkaline detergent, such as urea or toothpaste, to the surface of the diamond, then rinse it with water and dry it with a soft cloth.

If the black spots persist, try using an alkaline detergent, such as urea or toothpaste, to apply it to the surface of the diamond, then rinse it off with water and dry it with a soft cloth.

Fellow, I really didn't understand, I can be more specific.

Hello, glad to answer for you! The black spots visible to the naked eye of the diamond may be caused by dirt on the surface of the diamond, which can be scrubbed with a small amount of soapy water dipped in cotton, then washed with water, and finally dried with a soft cloth to remove the dirt on the surface of the diamond. If the black spots persist, try using a base-varying wildcast cleaner, such as urea or toothpaste, and apply it to the surface of the diamond, then rinse off the void with water and dry it with a soft cloth.

Thank you for your patience. The above is all my answers, if you are satisfied, please give a thumbs up, and I wish you a happy life again, thank you.

It is very normal for natural diamonds to have black spots.

Of course, black spots affect their value, generally identified as flaws, according to the size and number of black spots, identify the level of defects, if the naked eye can not see, it is still passable, generally ten times magnifying glass can be seen, according to how much to determine the clarity level, generally set at the level above SI, if it is visible to the naked eye, it will be set at the level below SI. Seriously affect its value.

It may be that there is no cleaning, and the dirt formed by the oil on the bottom is sent to the store to be washed.
