The easiest way to identify sapphires, the easiest way to identify sapphires

The so-called sapphire mirror is mainly polished from sapphire crystal, so what is sapphire crystal? Sapphire crystal: synthetic of alumina, with a hardness of 2200 2300 Domain, its hardness is second only to diamond, completely preventing surface wear.

Sapphire crystal can't be ground on the ground or on ordinary glass? No, because the ground or ordinary glass may contain diamond or diamond powder and sundries, if it touches it, it will scratch the sapphire crystal; Another situation is to encounter a softer substance than the sapphire crystal sticking to the sapphire crystal, resulting in the sapphire crystal being scratched, which is an illusion scratch, which can be polished and restored by the master. To identify whether the mirror is a sapphire, you only need to identify whether the material is sapphire crystal, and there are two simple and effective methods:

Drip method: drop a drop of water on the glass, and the water droplets diffuse to indicate that the material of the glass is ordinary crystal, if the water droplets do not diffuse, it is a sapphire. ②

Nail scraping: Scratch the glass with your nails, if there is a sense of blockage, it means that the material of the crystal is ordinary crystal, if it feels smooth and has no resistance, it is sapphire.

If you drop a drop of water on the crystal and the water droplets diffuse, it means that the glass is made of ordinary crystal, and if the water droplets do not diffuse, it is a sapphire.

1. The biggest feature of sapphire is that the color is uneven, and it can be seen that the parallel hexagonal cylinder is arranged, with straight color bands and growth lines of different shades.

2. The development of poly sheet double crystal, common louver double crystal pattern. The cracking is mostly split along the double crystal plane.

3. Strong chromaticity, sapphires from different origins in the world have their own characteristics in addition to the above common characteristics.

Depending on the geological origin, there are two categories: one is sapphires from Myanmar, Sri Lanka and Kashmir, India. The other category is sapphires from Australia, Thailand and China.

Sapphires from Myanmar and other properties are bright blue because they are colored by titanium, with silk rutile and fingerprint-like liquid inclusions.

Serial-like rutile inclusions produce six- or twelve-shot starlight and are a high-quality gemstone variety. Sapphires from Australia, Thailand and China are colored by iron because they contain more iron, so the color of the gemstones is very dark, and the reflective effect of faceted gemstones is not very good.

The easiest way to identify sapphire: Ha gas test, sapphire identification certificate, mutual scraping method, lighting method, and looking at the pattern.

1. Ha gas test.

It is necessary to do it when we breathe, and it is also an effective way to identify sapphires. Record the time it takes for this layer of fog to fade slowly but eventually disappear. The fog on the surface of a natural gemstone disappears in just a few seconds, while an artificial sapphire takes about 5 seconds.

2. Sapphire identification certificate.

For any gemstone, a grading report is a must, after all, it plays a very important role in the gemmologist's ability to detect the authenticity of sapphires and determine the type of gemstone. After the gemstone has been analyzed, the gemologist will issue you a report. The report will state whether the gemstone is natural or synthetic, whether it has been treated, and many other properties of the gemstone.

3. Mutual scraping method.

If you have two sapphires, and one of them is absolutely real, use the real one to scrape the other. Gemstones of the same hardness will not scratch each other, so when both sapphires are **, scratching each other will not cause any damage to the gemstones. If a real sapphire scratches another piece, the other piece is fake, or at least defective.

4. Lighting method.

For gemstones, it is shiny, and for sapphires, it can also be identified by the lighting method, if the gemstone is real, you will only see the same reflected light as the gemstone's color. If the gemstone is fake, i.e. made of glass, then you will see light of other colors in addition to the same color as the gemstone.

5. Look at the lines.

The authenticity of sapphires can also be identified by looking at the grain. Natural sapphire can be seen from its appearance clear and natural lines, and the lines have three layers, and the characteristics of its internal crystals are more obvious. Fake sapphires do not have natural textures and have a messy internal crystal structure.

Thank you for your patience, dear The easiest way to identify a sapphire? The easiest way to identify a sapphire is by looking at its characteristics such as color, transparency, hardness and luster. Here's how:

1.Color: The color of a sapphire should be dark blue or light blue, if the color is too light or too dark, it may not be a true sapphire.

2.Transparency: A true sapphire should have some transparency that allows the internal structure to be seen through the light.

If it's completely opaque, it may be artificial or something else. 3.Hardness:

Sapphire is very hard and can be scratched with a steel knife or a glass knife with a silver pat. If you can scratch the marks, it is not a real sapphire. 4.

Luster: Real sapphires have a good luster and can reflect beautiful brilliance. If it doesn't shine or has a dull and enviaging hue, it may not be a true sapphire.

The easiest way to identify sapphire:1. Look at the ridge patternTo identify the authenticity of sapphire, you can see the texture, natural sapphire can see clear and natural lines from the appearance, and the texture has three layers, and the internal crystal structure is also more obvious. Fake sapphires do not have natural textures and have a disordered internal crystal structure.

2. Lighting irradiationSapphires can also be identified by illumination, and when Pi Yinxiang places the sapphires under the light to observe, the real sapphires will show a lighter color in strong light, but will appear dark blue or blue in daylight. The counterfeit sapphire is made of topaz or plastic, and does not change in any way under the light.

3. Test the hardnessIdentifying the authenticity of a sapphire can also test its hardness. Sapphire has a hardness of 9 on the Mohs scale, second only to diamond and moissanite, if you use a topaz or other gemstone with a hardness of 8 to scratch the sapphire, the surface of the sapphire will not be scratched, if there are scratches on the surface, it means that the sapphire is synthetic.

Summary. The method of identifying sapphires is as follows: Color:

The color of the sapphire should be a vibrant, full, uniform blue with no variegation or spots. The darker and fuller the color, the higher the value. Transparency:

Sapphires should be transparent or translucent, with no visible cracks or bubbles. The higher the transparency, the higher the value. Cut:

The cut of a sapphire should be symmetrical, with no visible cut marks or blemishes. The finer the cut, the higher the value. Weight:

The heavier the sapphire, the higher the value. However, weight is not the only criterion, other factors need to be considered. Impurities:

Impurities in sapphires can affect their value. Some common impurities include iron, titanium, chromium, etc. If the sapphire has a high level of impurities, its value will decrease.

The method of identifying sapphires is as follows: Color: The color of sapphires should be vivid, full, uniform blue with no variegation or cherry spots.

The darker and fuller the color, the higher the value of the chain filial piety. Transparency: Sapphires should be transparent or translucent, with no visible cracks or bubbles.

The higher the transparency, the higher the value. Cut: The cut of a sapphire should be symmetrical, with no visible cut marks or blemishes.

The finer the cut, the higher the value. Weight: The greater the weight of a sapphire, the higher its value.

However, weight is not the only criterion, other factors need to be considered. Impurities: Impurities in sapphires can affect their value.

Some common impurities include shed iron, titanium, chromium, etc. If the sapphire has a high level of impurities, its value will decrease.

Can you add, I don't quite understand it.

Hardness: Sapphire is very hard and can be tested with a hardness tester. If the hardness of a sapphire is higher than 7, then it can be confirmed that it is a real sapphire.

In conclusion, identifying sapphires requires a combination of factors, and it is recommended that you consult with a professional or a regular jewelry store before purchasing sapphires to ensure that you are buying a sapphire that is in the state and in the right direction.
