Question: want to buy a yellow crystal bracelet gave my girlfriend, how to identify it’s true and false?
Best answer: yellow crystal bracelet is now deeply loved by women, the method of identification of yellow crystal has the following:
First, optical identification
Glass is a non-crystalline homogeneous body, the crystal is a crystalline heterogeneous body, rotating 360 degrees in the polarizer is like a dark change is the natural crystal, there is no change is false crystal. In addition, some natural crystal such as amethyst has dichroism, fake crystal is not.
Second, thermal conductivity test
The thermostat will be adjusted to the green 4 grid test gem, natural crystal can rise to yellow 2 grid, when the area rose to a large yellow, and fake crystal does not rise.
Third, hair identification method
Natural crystal is a birefringence, the yellow crystal on the hair, gently turn the spar when you turn to a direction when there will be double shadow phenomenon, and pseudo-crystal can not do.
Question: want to buy string of rosewood hand string to the elders to wear, and now the market so much rosewood hand string, then how to identify it?
Best answer: rosewood hand string texture hard, delicate, shiny, with a special Cartier love ring replica aroma, widely loved by the people. So what is the method of identification of rosewood hand string?
In a variety of hardwood rosewood wood texture is the most fine, the heaviest weight of wood, wood is not obvious. Rosewood wood flowers on the white wine, wood flowers will be immediately broken down into pink, and the formation of more sticky gum with wine, dumping can be even into the line, which is an effective way to identify rosewood.
First we identify from the color. Rosewood sub-new, old two. The former color is more red, while the latter color is purple; new red sandalwood soaked after the water fade, the old sandalwood immersion does not fade; in the new rosewood on the color can not afford, the old red sandalwood hit the color of a rub off. This is also the most intuitive way to identify rosewood bracelets.
Second, we can observe the texture of rosewood bracelet to identify. Rosewood texture curly obvious, known as “cowning pattern”. Rosewood chord cut along the trunk of the spindle or wood texture direction, not through the pith and parallel to the ring or with the wood rays into a vertical longitudinal section of the gold filament thin sparse, looming, visible regular peaks.
And finally through the test method to identify. Rosewood wood fine, but the weight is very heavy, into the water that sink; scraped some rosewood, into the alcohol, alcohol will become wine red or red sandalwood across the paper, leaving the red scratches that is true Of the rosewood bracelet.
Q: want to buy a bracelet to a friend, is to buy ice jade bracelet good? Or Xiuyu bracelet good? What is the difference between them?
Best answer: Xiuyu Chinese history of the four famous jade one. Xiuyu and ice kind of jade is very similar, then we Xiuyu and ice kind of emerald in the end what is the difference? First of all from the density point of view, the density of ice jade emerald than Xiuyu large, that is, and the emerald on the palm of your hand weigh compared to Xiuyu on the palm of the hand almost no weight. Second, from the gloss point of view, the ice is the jade luster of the unique glass luster, and Xiuyu is the ordinary waxy luster. Finally from the color point of view, Xiuyu’s background is obvious yellow-green tones, and ice kind of emerald most of the background is white.
If you are from the durability, ice hardness of jade than Xiuyu high, but the toughness of Xiuyu than emerald high, so if you are often easy to knock to the words, then the Jade bracelet is good, Do not wear ice kind of jade, and Xiuyu bracelet will be more appropriate; but from the benefits of the human body, both are similar.
Question: Now jade is deeply loved by us, there are a variety of jade on the market, then how can we identify good jade?
Best answer: What is the true and false identification method of jade? I believe for the love of jade who are want to know.
Jade can be divided into two kinds of soft jade and jade, jade, also known as jade. From the chemical composition point of view, soft jade is calcium, magnesium and iron silicate, and hard jade is sodium and aluminum silicate.
Here to talk about authentic jade true and false way:
First, water identification method
Will drop a drop of water on the jade, if into a dew-like, long time is Cartier nail bracelet replica true jade
Second, hand touch method
If the real jade, hand touch with a sense of cold lubrication.
Third, observation method
Jade will be observed in the light, the color is clear, the green is evenly distributed jade.
Fourth, tongue identification method
Tongue licking really jade astringent feeling, and false jade is no
Q: water foam and ice kind of jade from the appearance looks very similar, then the two specifically what kind of difference?
The best answer: water foam is a kind of ice and jade looks very similar to the “ice” jade. The main mineral composition of water foam is albite, water foam and ice species of emerald differences are the following: First, the water foam is not obvious, this is very different from the ice kind of jade; two, both Density, water foam than the ice kind of emerald light on a lot; three, both in the refractive index, gloss, grain and other aspects are also different.
So when you buy ice in the emerald can be divided by the weight of the way to distinguish between the water foam and jade, for the novice, in order to insurance, or the seller issued a certificate of identification, and the certificate to do a retest to prevent false certificates.
Other answers: because they are transparent, but the ice emerald issued by the fluorescence is more introverted, and water foam issued by the light more divergent, in fact, like a crystal of water, pure white, transparent. The ice kind of jade often have some background color.
Question: Recently want to buy a group of amber hand string to give away, but I heard that there are a lot of false amber on the market, then how to identify it’s true and false will not buy fake it?
Best answer: Amber is now sought after, many unscrupulous traders to see the interests of the amber market, there have been made of synthetic resin resin amber to pretend to be natural amber, let us look at how to identify amber.
First, natural amber texture light, into the water will sink, but the amber put in 1: 4 of the salt, the natural amber will float up, the fake will sink. Amber density between 1.05-1.10, the texture is very light.
Second, if the individual on the sound and color feel better words. Can be identified by the following method, the amber on the hands of gently rub will be issued soft and slightly dull sound, fake sound will be more crisp. Natural amber in the sun, the angle is different, the color depth and refraction is different, and the fake no such effect. Put amber on the detector under the UV irradiation, natural amber will be issued green, blue, white and other fluorescence, and fake will not change color.
Third, if the simple identification is not afraid of damage caused by amber, then, through the acupuncture and ether method. With hot red amber skin, natural amber will be black, but not sticky needle, and rosin taste. Fakes will be sticky needle also drawing, and even plastic taste. Or with ether nail polish with water, wipe the surface of amber, natural amber no reaction, and fakes will be corroded.
Fourth, there are some empirical methods to identify, the accuracy is relatively low, but better than easy. (1) friction with static: the amber in the clothes after the friction can attract small pieces of scraps of paper. (2) feel: a neutral gem, the general situation will not overheating too hot. While the imitation of amber with glass will have a cool feeling.
Other answers: As the amber counterfeiters are also constantly innovation, so look at amber is not true, alone, a way is obviously not enough, to multiple analysis, but amber is nothing more than plastic, waste suppression (that is, The so-called second generation amber) and Coba.
One, placed in the saturated salt water (water has been fully melted salt, was saturated, has been unable to dissolve the salt), the real amber is drift up, if not drift, it is to buy plastic
Second, is the effect of UV fluorescent lamps, to see whether the natural color
Third, feel, amber is not as slippery as plastic
Fourth, look at the pattern of amber inside. Because some of the use of waste to suppress, but also with salt water floating in the UV fluorescence Dengxia color change and feel and other amber characteristics, because his nature and the same as the amber, but is suppressed, but this international standard can not be called For the amber, but because each year the formation of amber is not the same, pressed out, then the edge of the Department will have vascular lines.
