The methods to distinguish between silver and platinum include: checking the imprint, color and texture, firing method, checking for oxidation, weighing, etc.
1. Look at the imprint
Metal jewelry usually has relevant ingredient labels, while platinum jewelry is labeled as "PT, PLATNUM, PLAT"; The identification of silver jewelry is: “S925、Ag925、S990、Au990”; Silver plated and silver coated jewelry are marked as: “SL、FS”.
2. Look at the color and texture
Platinum has a grayish white color and a hard texture that is not easily deformed; Silver has a relatively pure white color, a soft texture, and a shape that is easy to change.
3. Burning method
Due to the different melting points of platinum and silver, platinum and silver have different melting points. Platinum generally does not melt when burned at high temperatures, but silver turns black red after being burned at high temperatures.
4. Will it oxidize
Silver has unstable properties and is prone to oxidation and blackening, while platinum has stable properties and is unlikely to fade. After being left for a period of time, observe the changes between the two. Silver is oxidized and blackened, while platinum remains unchanged.
5. Weigh it
Platinum has a higher density than silver, so at the same volume, platinum is heavier than silver.
