How to identify the authenticity of rubies?

Rubies can identify authenticity from the aspects of color, luster, and cutting technology.
1. Appraisal from the color
The natural ruby ​​is not very pure color even if it is pigeon blood red. The formation of the gemstone causes the color to appear local or a little uneven.
usually the natural ruby ​​color of the genuine product is relatively soft, and the eyes are very comfortable to observe; if it is fake, it will be dazzling to observe.
2. Appraisal from the gloss
The natural ruby ​​and fakes with genuine products have very obvious differences in gloss.
The gloss emitted by the genuine product is gentle and soft, and it will present several different luster; and the fake goods are artificial ruby, which emits glass luster. Under strong light, its glass luster is particularly obvious, which is also a unique feature of artificial rubies.
3. Appraisal from the cutting process
News are one of the very important factors.
The high -quality ruby, the process processing process is very strict, and each link needs to be strictly controlled. The rare natural ruby ​​is not allowed to be artificially damaged. Therefore The gloss is perfect.
The opposite artificial gemstones are casual, and cutting is relatively rough.
The expansion information
Theat is one of the precious varieties in jewelry.
The ruby ​​color is bright. Under the light source, it can reflect the beautiful and moving six -shot starlight. It is commonly known as the six lines. This is caused by the special crystal structure of ruby ​​and is a unique optical phenomenon.
The ruby ​​is transparent, translucent and opaque, and the color is different from the depths of water red, pink, pigeon blood red, rose red. Because large gemstones are very rare, the larger ruby ​​that is usually seen is generally fake.
has two cases of fake rubies:
The first is to impersonate rubies with low -grade red color gemstones, and there are no rowers in the fake ruby ​​unique color and light.
The second is artificial ruby. Artificial ruby ​​is very similar to natural rubies in terms of proportion, hardness, and color.
The intuitive judgment, the artificial ruby ​​texture is uniform, no natural impurities, uniform color and positive, often the particles are large, lack of natural sense.

At present, there are four methods of synthetic rubies on the market: flame melting method, fuse method, water heat method, and crystal tiramium. Different methods are almost consistent with the physical and chemical properties of ruby, so growth characteristics have become important identification characteristics.
. Flame melting method synthesis of ruby ​​(1) Surface appraisal characteristics
1. Original crystal: Flame melting synthetic ruby ​​original crystal is pear crystal, and there are also pear crystal crushing and impersonation of natural ruby ​​wool Case.
2. Color: Flame melting method Synthetic trace elements in ruby ​​are single, and the color is pure and gorgeous than natural ruby. With the development of the synthetic process, the color of the flame melting method is more and more colorful, and the color can only be used as auxiliary appraisal characteristics.
3. Crack -shaped surface texture: Synthetic ruby ​​is sometimes not carefully polished, and it is easier to produce crack -like surface texture. It is also called "fire marks" or "tremor".
(2) Internal synthetic features

1. ) It is an important basis for the difference between the flame melting method to synthesize ruby ​​than the natural ruby.

2. Bubble: Generally, it is spherical, and there are stretching bubbles. It is called "tadpole" bubbles, and the bubbles are often perpendicular to the curved growth pattern.
3. Small powder: Without a complete melting raw material powder, it will remain in the growth crystal.
(3) Luminous
The natural ruby ​​and flame melting synthesis Ruby can be red fluorescent under ultraviolet light. Most natural ruby ​​contains FE elements, which will weaken its fluorescent effect, manifested as inert or weak red fluorescence, while the flame melting method synthesizes ruby ​​to the color element, and the red fluorescent is strong. When observing ruby ​​with Charles filter, the flame melting ruby ​​can show more obvious red. Other methods have similar phenomena to synthetic rubies.
tips
The difference between flame melting method synthetic ruby ​​and natural gemstones: The starline of the synthetic starry ruby ​​is only on the surface of the sample, the star line is complete and clear, and the starline is thinner (Figure 2). The star line in the natural ruby ​​is produced inside the sample. The starline is thicker and may have the characteristics of lack and incompleteness.

The pinch gold red stone buns in Starlight Ruby are often smaller than the needle in natural starlight gemstones, and the curved growth pattern is obvious (Figure 3) Essence

. The melting agent synthesis of ruby ​​(1) Surface identification features
1. Original crystal: The molten melting method synthesizes ruby ​​crystal is mainly plate -shaped and granular.
2. Color: Following agent is rich in color, including various reds of different shades.
(2) Internal synthetic features
1. Metal tablets: The melting agent method synthesizes the inner of the ruby, the platinum slices peeled from the platinum pupa, the platinum tablets can be triangular, hexagonal, or irregular multilateral shape. The probability of platinum slices is low.
2. Following agent residual: The most important solid bag in the molic agent synthesis of ruby ​​is the residual of feldling agent. These fuse remnants often have specific colors and forms (Figure 4-6).

. Water and heat method synthesize ruby ​​(1) Surface appraisal features
1. Primitive crystal: Water heat method synthetic ruby ​​crystal is mostly thick plate -like to plate -shaped, each can be seen on the crystal surface. Planting growth pattern.
2. Color: At present, the synthetic ruby ​​synthesis of the water on the market may have various colors with light red to dark red. Often, the transparency is very high and the interior is very pure.
(2) Internal synthetic features
1. Species: Water -Heat growth crystals need to use species chips. The species chip has obvious boundary lines with ruby ​​on both sides, but often removes during grinding. There are sometimes some irregular crystal buds and fog buns on both sides of the chip.
2. Growth pattern: The growth pattern is often different, and the shape is jagged, ripple -like (Figure 7, 8).

3. The "nail -shaped" fluid bodies of the species sometimes become very small in nail -shaped wraps, manifested as a densely rooted and directional arrangement.

4. Metal parcels: They are decentralized or localized, which can have a polygonal shape such as triangle and quadranges. It is opaque under transmission light and can have metal luster under reflection light.
Note! As synthetic technology becomes more and more mature, the characteristics of synthetic rubies are not obvious than before, and even internal characteristics are the same as natural ruby. To determine the natural nature of rubies, you need to go to a professional appraisal agency for testing. rn合成红宝石的命名：Synthetic Rubyrnrn天然红宝石的命名：Natural Rubyrn以GUILD证书为例：rnrnrnr n

There are many people and rights, the more red the gems are! With the advancement of technology and the price of rubies rising one after another, more and more people have seen their attention on forgery ruby. If it is too inconvenient to send it to the inspection one by one, Yicheng summarizes six easiest ruby ​​appraisal methods. The first step of screening with the naked eye, and it is more convenient and fast to send it to the laboratory. Babies who like rubies quickly learn!
Observation color: Because the natural growth environment is very harsh, natural ruby ​​is often uneven in color. It can be visible inside
Ruby is extremely pure, with high saturation, and unnatural colors.
Observation of gloss: Diamonds have several different gloss. Ruby generally has glass luster or strong glass luster. When we pick up a ruby, we can observe whether it is glass or strong glass luster, especially under the irradiation of strong light, the color will become more bright, and the local or overall has unique silk -shaped flashing, gloss Quite strong.
Observing dual -color: Natural ruby ​​often has obvious dual -color, and the method of observing dual -color is also very simple. Red changes, while other imitation products do not have this characteristic.
Observation Ruby with cat eye or starlight effect: Ruby with special optical effects is a special ruby. When observing it, it should be observed. In addition, the starlight is divergent, which is relatively irregular, and there are bright spots in the middle; the lines of the synthetic ruby ​​float on the surface, and the lines are clear and obvious. The star line is more regular.
Observation and cutting: We generally observe that high -quality natural red and sapphire processing are very careful during processing, and they are carefully polished during the processing process. It is rough during the processing process. It can be seen that polishing marks and tremor or fire marks caused by rapid polishing are often polished.
