There is very little difference between platinum and silver jewelry. Those who are not knowing anything or less knowledgeable in terms of jewelry will fail to differentiate between the two. But with little practice and regular contact with this jewelry can teach you to determine silver jewelry and differentiate it from the platinum jewelry.
Here are some of the ways following which one can tell the difference between the silver and platinum jewelry.
Examine your jewelry
First of all, you have to locate a mark on your jewelry so that you can identify it. Marks can be made on the metals of the jewelry or the back of the clasp of the jewelry. If your jewelry has not any marks, then it is not precious jewelry.
One can look for the marks which indicate silver jewelry or can a stamp with the number ‘999’, which tells us that the jewelry is made up of pure silver. If the stamp is of ‘925’ followed by the letter ‘S’, then it is sterling silver which is 92.5% pure silver.
Platinum is a very expensive metal and that’s why all the platinum jewelry will be marked for purity. One can look for the word ‘PLAT’ or ‘PLATINUM’ followed by the number like ’950’ or ‘999’. Platinum jewelry marked with ‘999’, is the pure platinum jewelry.
Precious metals are not magnetic and hence they didn’t react to the magnet if you run one of those around it. However, some of the platinum jewelry can be attracted by the magnet because of the presence of cobalt as an alloy in the metal to make it hard. If sterling silver is attracted by the magnet, then contact your local jeweler.
Using an acid scratch testing kit
One can use an acid scratch testing kit for the testing of silver and platinum jewelry. If your jewelry has no marks or stamps, then you can use this method to test the authenticity of your jewelry. Purchase this kit from any of the shops and don’t forget to buy gloves so that you can remain safe.
After that, take a black slate and rub the jewelry on it in back and forth motion. Make 2-3 lines on it by using the back part of the jewelry. Apply the towel to the work surface part and protect it from scratches.
After getting rubbed, dip the lines in acids separately. Make sure that you are dipping the lines one by one otherwise it may affect the results. Wear gloves for the protection of your hands.
Now, this is the time to observe the results. If the lines disappear completely, then the jewelry is not of platinum or silver and if the line remains there, then the metal is pure silver or platinum.
The testing solution directly on silver
One is advised not to use this acid test for soft and decorated jewelry as it will hamper the jewelry. One can purchase a silver testing solution directly from a store.
Drop a small amount of testing solution on that part of silver which is inside. If the testing jewelry is a necklace, then use the back part of it. Wear gloves while the testing and avoid using clasps of the jewelry for the test.
The acid will turn into dark brown and then in a different color. If it turns into a different color then the jewelry is pure. If it turns into dark or bright red, then the metal is pure.
Finally, after the test clean your jewelry with water and dry it using dry clothes or towels. While cleaning the jewelry, use a sieve so that it may not fall into the drain.
Testing jewelry with hydrogen peroxide
- Fill hydrogen peroxide in the glass so that the whole jewelry can be submerged inside it completely. You can find it in any of the grocery stores.
- The hydrogen peroxide will bubble immediately when coming in contact with platinum. If you are putting silver, then take it out and a small bubble will form on the jewelry.
- After that, rinse your jewelry well using a sieve in the drain so that you may not lose your jewelry.
These are the ways that can be followed to find that your jewelry is genuine or not. One can follow any of these to check the authenticity of silver and platinum jewelry.
