The standard of choosing sapphire is similar to the diamond 4C standard, but it is different from the important degree of sorting: color (the most important indicators of color gems), transparency, cutting, weight.
Ilons are the most important reference indicators for buying gems, and the value of gems is also highly positively related to color saturation.
A sapphire seeps into the iron and titanium during the process of mineral crystals, so it presents blue. The number is more than the ruby and the particles are large. It is gray blue, green blue, light blue, purple blue and so on.
Thenian sapphire is relatively clean. Occasionally, the straight strap can be seen, rotating the ring surface, and observing different directions from the waist circumference. Different blue and green can be seen. Pay attention to the color of the artificial blue gem is bright and uniform, blue, light blue, purple blue, and there are no defects inside.
2. In addition, non -professional customers buy sapphire, and can also refer to the indicators given on the certificate as the basis for judgment. Common international certificates such as GRS.
Buying high -quality sapphire is mainly based on the following aspects:
The size: the larger the gem, the more precious the sapphire, and the sapphire is no exception. Sapphire is used to carats.
The transparency: sapphire from transparent to opaque. In addition to the transparent sapphire, the more transparent the value of the sapphire is, the higher the value of the sapphire. Many of the opaque sapphire under the naked eye observation is transparent under the flashlight or strong light.
The color: Because the sapphire in the broad sense can have a variety of colors other than red, and the sapphire of various colors has its own characteristics, the choice of sapphire color should be dependent on the specific situation. Overall, the most popular color is the chrysanthemum blue, which is blue with a slightly purple tone. The most famous sapphire of chrysanthemum chrysanthemums is Kashmir sapphire and produced in the Kashmir area. However, due to the high altitude of the production area and snow all year round, the high -quality sapphire produced is very rare (now almost inactive). Therefore Sapphire is almost extinct. The current Kashmir sapphire is only regarded as a variety of sapphires in business, and the high -quality sapphire of the chrysanthemum of the chrysanthemum is called Kashmir sapphire.
In internal parcels: Natural sapphire crystals often have ribbons, small needle -shaped golden red stones, spinels, etc. Another feature package is a fingerprint wrap. The parcel is the mark of the gem, and the natural gem could not be without the parcel. However, too much parcel body will sometimes affect the beauty of the gemstone, and it will also have a great impact on value. Therefore, the more clean inside it is when buying sapphire.
Starlight effects: Sapphire of the same size, color, and quality, if there is a starlight effect (that is, star light sapphire), the value of sapphire is much higher. The starlight effect of sapphire is mostly six shot starlight, and there are rare twelve shot starlight. The more complete the starline, the clearer the more complete, and the higher the value.
The sapphire on the market is mainly sapphire produced by Myanmar and Sri Lanka, and sapphires produced in China, Australia, Thailand and other countries also occupy a certain percentage in the market. Shandong sapphire in China has the ink blue of special beads, and there are fewer internal defects. After the heat treatment is changed (a optimized processing method recognized, it does not need to be specifically indicated during sale), it can show a very bright and rich color. Like to be loved by the working class, it is very popular in the northern market in China.
The as sapphire in the market, the most common is glass. In fact, it is easier to identify glass. The glass came out of the high temperature. After cooling, it contracted naturally, and the plane was sunken inward. This depression phenomenon is not easy to find. You must use the magnifying glass to use the magnifying glass, you cannot focus directly on the line. You should be obliquely focused. It is easy to find the concave surface. The depression is usually glass. The polishing and polishing of gems usually achieve a very flat effect. Another identification method is that there are many types of parcels in the glass, the most common is air bubbles, while gems do not have bubbles. The bubbles in the glass can be found with 10 times the magnifying glass observation.
The also a sapphire as sapphire, an artificial synthetic sapphire. The identification method is to see the texture of the texture first, whether the structure of the texture is naturally crystal, and the natural crystals are often messy and disorderly. Authentic. The synthetic sapphire is often very orderly. Of course, many synthetic sapphires are clean and flawless, which is usually fake. Because natural gems are always impurities, there are almost no cleanliness. This synthetic sapphire is often dazzling in color. The glorious is very shallow, and there is no deep sense of natural color. The natural gem color is high and not dazzling, and the glory shoots naturally from the inside.
It to buy sapphire is best to observe with the naked eye under white light. Do not observe with strong light, because the blue color seen in the naked eye in the white light is the most correct. High -quality sapphire should be transparent. When rotating the sapphire that has been considered, you can see the jumping blue light. It is best to buy sapphire without cracking flaws, and there are obvious cracks sapphire, which is not too valuable. From the colors to evaluate, the blue sapphire with a slightly slightly purple sapphire is the most valuable.
. In addition, if you buy sapphire jewelry, if you are particularly expensive, it is best to ask for an appraisal certificate. This is the practice of the international jewelry industry.

Let ’s provide you when you buy sapphire:
. Color
Under the background of white paper, look at the four aspects of the blue:
positive : Refers to whether the blue is pure blue (some will have purple or green), of course, the better the pure blue. It is easy to see as black. (China
The sapphire produced in Shandong Province is that its color is deep and black and affects the quality level)
Blue is better.
Mless: refers to the degree of uniform color distribution. It should be the more uniform. .
. Bad defects
are often referred to as more or less impurities (also the size of "flower"), whether there are traces and cracks of bumps. Professional observation and evaluation, as long as you look at the transparency when you buy, you can do it (there are many impurities, the transparency is reduced). When buying, you should pay special attention to whether there are traces or cracks of bumps.
. N gems are often cut into a shape (oval, round, pear -shaped ...). See whether the shape of the shape is symmetrical, whether the grinding angle is suitable (if it is not appropriate, it will leak light and reflect the light. Not bright), and whether the polishing kung fu is in place (those who do not polish enough will also make the gemstone reflect light).
. The size of the particle size
Choose small grains (0.5-2 carats); if you make noodles or pendants, select the grains (1-2 carats per grain) or larger grains (2--3 carats per grain), each, 2--3 carats), and each (2-3 carats), each, Of course, the conditional can be selected (more than 3 carats weighs above 3 carats).
In again to mention the precautions when buying:
u003C1> should be avoided when buying. Look at the color under the normal tungsten wire.
u003C2> If you buy the inlaid sapphire jewelry (such as a ring, a pendant), it depends on whether the metal claws are inlaid and the gemstone is inlaid. .
u003C3> The seller should be required to show the appraisal certificate (identified by a qualified department, with legal effect), to distinguish whether it is true sapphire.
u003C4> If the transaction is selected, do not forget to forget it, do not forget to be Ask a regular invoice. In the future, you can use this free cleaning, or if a quality problem occurs, you can protect your legitimate rights and interests.
u003C5> In the current market ) The colors are more bright. "Thai sapphire" is some of which uses China's Shandong sapphire through Thailand to change color (from dark color to lighter colors) to the market in our country. They are all Shandong sapphire. When buying, you can choose according to your preference.
I wish you buy the sapphire of your heart !!!
(Zhongxiang Jewelry) Of course, the sapphire is still selected according to the 4C standard. 4C is: color, clarity, cutting, weight. First of all, it depends on color and fire. The vivid the color, the more pure and uniform, the higher the saturation, and the more the gems have the collection value. Secondly, see the net degree, that is, to see if there are impurities, defects and cracks. Then we look at the cutting workers. If it is face -to -face sapphire, it depends on whether the face is symmetrical and the cutting ratio of the overall gemstone. Finally, in the same conditions, the larger the sapphire, the better.
