Easy to distinguish between diamonds and fake ones


The diamond's main features are: excellent thermal conductivity, a high hardness, typically adamantine luster beautiful pastel dispersion, high refractive index, a homogeneous body, sharp engraved personally upon rib as well as the standard cut diameter and weight of the corresponding sex. Identify the genuineness of the diamond generally start from several angles.
First introduce several daily life more simple, without the help of a professional tool for the identification of methods:


I 〖stroke, identification method〗
Due to the lipophilicity of the diamond, you can oil pen (or pen) at the counter of the diamond plan, rest assured, genuine diamonds will not leave scratches, draw the line is coherent, real diamond no significant line or discontinuous, is likely to have a problem (taking into account the quality of a ballpoint pen, you can draw a few times).


II 〖breath identification method〗
Good heat transfer capacity of natural diamonds, heat scattered quickly. To test the diamond near the mouth gently exhaled air tested diamonds cast a mist, then immediately watched the mist of the diamond volatile situation for natural diamonds, the fog will immediately dispersed, and vice versa will fog remain for some time, will be dispersed in the counterfeit diamonds.

III〖Dripping identification method〗
The upper facet of the diamond wipe clean with the end of the toothpick dip drop of water droplets on it, real diamonds on the water droplets will show moderate small round drop shape. Fake diamonds on the water droplets will spread quickly.

IV〖Pencil identification method〗
Diamond moistened with water, using pencil carved on it, real diamond surface without leaving traces of pencil across. Transparent crystal, glass, tourmaline fake diamonds will leave marks.

V 〖to characterize identification method〗
The hardness of diamonds are strong in the top left, blades, and other difficult nicks. In addition, the diamonds in the glass gently draw, will leave an obvious white marks. Fake diamonds are no such phenomenon.

VI 〖light resistance identification method〗
Real diamonds with single refraction, radiant, dazzling brilliance of the characteristics on the hands you can not see the hand lines. Crystal posing as fake diamonds, its dispersion, low refractive index, visible through the crystal, hand lines.
Diamond wipe countertops (Diamond biggest facet) down on a piece of paper of lines, diamond cut standard of comparison, through diamonds to see less than lines on paper, while the vast majority of imitation Products allows sufficient light to pass through, at least part of the line can be seen.

VII 〖hand touched identification method〗
Because diamond oil kind of affinity human finger skin secretion of some trace grease with your fingers to gently touch diamond crystal face, there will be a sticky feeling. With a magnifying glass, but this method requires some experience, try a few times by hand to slowly cultivate a feeling. For polished diamonds inlaid hand touch, take a magnifying glass to view, you will find the diamond the the diamond substitutes or other precious stones stains more grease.

VIII 〖contact identification method〗
Diamond is crystallized carbon, excellent thermal conductivity paste Touch Diamond, tongue, cheeks, back of the hand, the human body is a constant temperature, if the diamonds will warm up, and that is imitation. Real diamond paste touch for a long time it is cold.

Let's introduce some identification with the professional tools or complex point:

IX 〖cut mirror identification method〗
Diamond cut mirror to observe, within the natural diamonds will find bright, has many complex facets. And other counterfeit goods bland, cut, or even can not see.

X 〖thermal conductivity meter identification method〗
Identify genuine and fake diamonds accurate and reliable diamond tester (ie, thermal conductivity meter) measured the thermal conductivity of various diamond substitutes or counterfeits distinguish between true and false diamond problem solved. Diamond thermal conductivity meter to detect the maximum thermal conductivity of diamond this feature, if it is a natural product, thermal conductivity meter can be called a beep and red, which is the most accurate and convenient method for the identification of diamonds.

XI 〖hardness tester identification method〗
Standard hardness tester to measure the hardness is also simple and reliable method of identification of diamonds. Standard hardness tester is a size of only 65 × 55 × 23 mm rectangular box, lifted the lid, inside lined with four precision-ground, surface smooth as a mirror standard hardness piece Mohs hardness were 6,7,8,9. Characterize the hardness of 9 standard piece can draw scars is a real diamond, where the program does not automatically prove its hardness is less than 9 or equal to 9, are fake diamonds diamonds.

XII 〖certificate query identification method〗
Purchase polished diamonds inlaid jewelry merchants usually jewelry certificate of authenticity. This is the most accurate and detailed quality description of the diamond. The appraisal certificate provider with industry professionals, the reliability of the certificate can simply related sites to check the authenticity of a position of authority. As long as the query to relevant sites jewelry appraisal certificate number, and basically do not doubt the authenticity of the diamond
