The authenticity of diamonds can be judged according to the following 10 methods
1. Observe the "fire color" of diamonds
the brilliance of diamonds is also called "fire color", which can reflect colorful and strange colors, especially soft and cool blue light. Due to the high refractive index and high dispersion value of diamonds, diamonds have this special "fire color", especially those with perfect cutting. Here, consumers can distinguish the authenticity of diamonds by identifying this special "fire color"
2. Whether the diamond is sticky by hand
since the diamond has an affinity for greasiness, if it is a real diamond, gently touching its surface with your fingers will give you a sticky feeling
3. Observe whether there is temperature
place the diamond on your arm or face. If you feel it is warm, it is a fake diamond. Because real diamonds do not transfer heat, no matter how you touch them, they are cool
4. Line test
place the diamond table on a piece of paper with lines. If it is a real diamond, the lines on the paper cannot be seen, otherwise it is a imitation of the diamond. In general, the diamond facet is opaque, so the real diamond cannot see the lines on the paper
5. Lipophilicity test
natural diamonds have strong lipophilic ability. When the oil-based water pen is used to draw real diamonds on the surface, it can leave clear and continuous lines. On the contrary, when the ink is scratched on the surface of the diamond imitation, it often gathers into small droplets and cannot appear continuous lines
6. Breath test
breath on the diamond. If the moisture on the diamond disappears immediately, it is proved to be a real diamond; If the water vapor stays on the diamond for several seconds before it disappears, it is a fake diamond
7. Wiping test
rub the diamond back on fine sandpaper for several times. If there are scratches on the surface, it is a fake diamond, and if there are no scratches, it is a real diamond.

8. Use the chemical properties of diamonds to identify diamonds.
during the identification, the diamonds should be moistened with water first, and then gently scribed with a pencil. On the crystal surface of real diamonds, there is no trace where the pencil cuts. If it is not diamonds, but glass, crystal and other materials, it will leave traces on the surface. In general, the accuracy of this method is high by using pencil to identify the true and false diamonds. However, when identifying, it should be noted that some old diamond jewelry inlaid should not be soaked with water, because if it is inlaid with copper or silver, it is easy to oxidize. In addition, in general, the crystal surface of the diamond also needs to avoid contact with oil, dust and objects
9. Specific gravity test method
there is a specific gravity liquid for measuring gems in the market. Citizens can put diamonds in the specific gravity liquid of diamonds, and diamonds will sink. Gems similar to diamonds floating on the specific gravity liquid are definitely not diamonds
10. Check the inlay
if you want to check the inlay of diamond jewelry, you need a secret weapon, that is, silk stockings worn by beautiful women. Because the exquisite inlays should be perfectly matched, when buying claw set diamond rings or other diamond ornaments, it is best to use the diamond face with claw set on the silk socks. If it is very smooth and does not scratch at all, it proves to be excellent inlay technology, and you can buy it with confidence. On the contrary, it indicates that the inlay is not close enough, and it is better to choose another one
extended data:
diamond refers to the polished diamond, which is a natural mineral and the original stone of diamond. In short, diamond is a simple crystal composed of carbon element formed under high pressure and high temperature in the deep earth. Diamond is beautiful and rare. It is a symbol of love and loyalty and represents eternal love
on May 16, 2017, Sotheby's auction house held a spring jewelry auction in Geneva, Switzerland. A pair of colored pear shaped diamond earrings set a new record in the auction history with a total price of about US $57.4 million, or about RMB 395 million. This pair of pear shaped earrings are produced in South Africa. Except for their different colors, they are almost identical in shape and weigh about 16 carats respectively. Among them, the dark pink diamond is called "Artemis", and the auction price is 15.5 million US dollars (106.7 million yuan). The other diamond is deep lake blue, called "Apollo". Because the color is more rare than pink diamond, the price is more than twice that of pink diamond
in January 2018, in the mining area of Lesotho, an African country, a 910 carat D-COLOR IIA diamond, equivalent to the size of two golf balls, was excavated, ranking the fifth largest in the history of diamonds
Hello, it's really hard to say about diamond rings. The diamond rings in online stores and physical stores have their own advantages. Physical stores have large expenses and relatively high prices due to high store rent and decoration labor costs. The online store has no store rent and other intermediate profit links, which is also based on the reason of small profits and quick sales, so the price is much better than that of the physical store. In fact, in order to buy a diamond ring, in addition to fame, we also need to integrate the price performance ratio of diamonds. The same diamonds, whether placed in physical stores or online stores, are of the same quality. I personally think it is unnecessary to buy them in physical stores at twice the price I think Shihua jewelry is good, small. Enterprise. Goose 596-013-23 thank you. nowadays, many people in the Internet world buy their favorite diamond rings online to send them to their girlfriends
When you go to the shopping mall for appraisal, you can spend only a few tens of dollars. Some don't need money. It's useless to say that. What you see is true!
