Platinum is naturally white in color and is the most expensive of all precious metals. In the modern world, platinum jewelry is a symbol of respectability and confidence. How not to be mistaken when choosing jewelry from this material?
Instructions
Step 1
When buying a piece of jewelry, be sure to look at the brand first. This mark has a different shape for different precious metals. For gold and platinum, a blade is used. In addition, you will see 900, 950 or 850 fineness on platinum products. While gold jewelry is 375, 500, 583, 750, 958.
Step 2
To distinguish platinum from white gold, note that platinum items are heavier. For comparison, hold in your hand two wedding rings, one made of platinum and one made of gold. Platinum should be about a third heavier.
Step 3
It is possible to determine that a piece of jewelry is platinum by wearing it. Platinum is a very durable metal, therefore, jewelry made of it does not deteriorate, practically does not scratch or wear off. While white gold has its own color due to a variety of impurities or rhodium plating. Therefore, over time, a product made of such a metal may acquire a gray-yellow tint, and the coating may wear off in places. Silver, in spite of its external resemblance to platinum, is a fairly soft metal.
Step 4
If you are not afraid of chemical experiments, you can do the following test at home. Apply 1 drop of gold chloride solution to the clean surface of the product. Evaluate the result in 40 seconds. This solution will have no effect on platinum. A dark green spot will appear on the silver.
