From the current level of people's consumption, platinum jewelry is favored by consumers. So let's take a look at the true and false nature of platinum jewelry .
Ways to identify platinum jewelry:
1, the color method: pure platinum is white, shiny, white K gold color is white to beige, silver color is white. The color can be distinguished from the surface.
2, hand rub method: Platinum density reached 21.45, through the same volume of material weight test, platinum has a heavy sense, it is heavier than gold (19.36), heavier than K white gold, but also heavier than silver (10.45).
3. Burning method: The melting point of platinum reaches 1773oC, which is much higher than that of K white gold and silver. Generally, the welding torch cannot melt platinum, and the authenticity can be identified accordingly. And the color of the platinum does not change after cooling.
4. Marking method: Platinum jewelry has a standard stamp. Internationally, it is expressed by PT or PD. For example, the color of PT950 platinum is 950%.
5, gas natural law: put the jewelry on the twisted gas stove mouth, put a few minutes if the jewelry turns red and heat up the gas stove, it is platinum products. This is because platinum can act as a catalyst to promote the exothermic heat of oxidation of gas and air, so that platinum is heated and reddened to ignite the gas.
6, point test method: A will put mercury on platinum, platinum will not be contaminated, and gold, silver will be combined with mercury and contaminated. B. Put some powder into the hydrogen peroxide bottle with a trowel on the side or middle depression of the platinum jewellery. Platinum can act as a catalyst to promote the decomposition of hydrogen peroxide, release oxygen and tumbling up and down.
In summary, the method of distinguishing the true and false of platinum jewelry, I believe you must have some understanding, please pay attention to China Jewelry Merchants Network for more details.
