Jewelry trap you stare
The "catty" that illegal traders play when selling jewelry mainly includes: only the foreign code, the clone certificate, the smashing inlay, the fish and dragon confusion, the fake filling, the shoddy, exaggerating the grade, missing the invoice and so on.
[Only standard ocean code] According to national regulations, gold, silver and platinum jewelry products should be printed with numbers and letters on their products. However, on the product label, the standard name, component content and special treatment process must be marked with Chinese characters. Otherwise, most consumers are hard to understand.
[Cloning certificate] The identification certificate is the "ID card" for jewellery and jade jewelry. However, the unscrupulous merchants have made a fuss about the jewellery "ID card": there are copying "cloning", there are flowers, and there are a batch of jewels. There is only one "group ID card".
[æªé“镶] A jewel and jade often needs to be inlaid to become a piece of jewelry. Since the inlaid jewels are difficult to accurately identify, the means are even more numerous. Common methods include Tibetan mastiff, spelling, padding, filling, coating, and dyeing.
[Shipping up] For a long time, the jewelry industry has created many superb techniques to improve jewelry, such as irradiation, acid immersion, injection molding, ochre and so on. However, if you do not express to the consumer whether it has been processed, it will be shoddy. For example, jadeite is filled with B and C goods, and irradiated with discolored or dyed pearls.
In this regard, the jewelry appraisers of the Liaoning Provincial Bureau of Geology and Mineral Exploration reminded consumers that when purchasing jewellery, they should pay attention to the identification certificate of jewellery, whether it is formal and effective; shop around, look at more, ask more questions, and ask the key words one by one. The exact meaning; pay attention to whether the craft style is desirable, and understand the potential value of the process and design.
[Listen to gold with your ears]
Look at the color. The higher the color of gold, the more golden the color.
Check hard and hard. Real gold jewelry is softer, the higher the purity, the softer it is, the more easily it can be bent, while the metal products such as thin gold and copper are harder.
Listen to the sound. The real gold jewelry fell to the ground without metal sound, and the voice was low and dumb.
Burn with fire. True gold jewelry will not change color after burning, and other metal products will oxidize and turn black after seeing fire.
[Taste the diamond with your tongue]
Oily test: Using a special pen or ballpoint pen with oil-based ink, draw a line on the diamond's countertop, leaving an unbroken straight line. Other imitations are intermittent dots.
Water Drop Test: Water drops will remain spherical on the diamond for a long time, while water droplets on the imitation will spread out in a relatively short period of time.
Harmonic test: Harmony on the diamond, such as the water vapor on the diamond immediately disappears into a true diamond; if the water vapor stays on the diamond for a few seconds before disappearing, it is a fake diamond.
Sensory test: Diamonds are much cooler than imitations when exposed to the diamond and its imitations at room temperature.
