Platinum and K gold can be distinguished from the following points:
Platinum is a natural pure white metal, and K platinum is an alloy of gold with palladium, nickel, silver and zinc, so it is also called K platinum.
Platinum is relatively rare, and its annual output is much less than that of gold, which is more precious.
The density of platinum is very high. A piece of platinum jewelry is 20% heavier than a similar piece of K gold jewelry.
Platinum is resistant to corrosion and oxidation by strong acid and alkali, and its chemical properties are more stable than that of K platinum.
