Platinum looks similar to silver but is worth significantly more. Other than a stamped inscription there is no quick method to 100% ensure the presence of platinum in a marketplace setting. Here are the best steps to help accurately identify platinum in your home.

Identify Platinum

Step 1

First look for the most obvious signs by looking for the symbol "PT" on the inside of a ring or the back of a watch. If there are no markings on the back of a watch that you suspect might be platinum, open the back part of the watch and look for an inscription on the inside of the back cover.

Step 2

Platinum has a very high melting point and will not discolour when exposed to heat like other metals. Place the jewelry in a metal spoon and hold it over a gas stove flame (use oven mitts to hold spoon). If the spoon changes colour and the jewelry piece does not than there is a high probability that it is platinum.

Step 3

Purchase a test kit that uses acid to check for the existence of platinum. By rubbing a jewelry piece on a test stone you can then check for a reaction with a drop of acid on the metal residue streak. Platinum is very stable and will not react immediately to the acid drops like other metals. These test kits cost about $20.
