SO HOW CAN WE TELL IF IT'S REALLY GOLD?
These steps can help you determine if your gold is real, and possibly what the true purity is. There are many suggested ways to test gold, and these are some of the most common:
Step 1:
Rub the piece of jewelry across a piece of unglazed porcelain tile. It should not make a black streak. If it does then it is pyrite.If the streak is golden yellow then it is gold. Unglazed porcelain tile can be found at a hardware store.
Step 2:
Use the Moh's scale to determine the hardness of the metal. Gold has a hardness of about 2.5 to 3 on the Moh's scale. Glass on the other hand has a hardness of 5.5 on the same scale. Try scratching glass with the piece of gold. If it scratches the glass, it is definitely not gold, or is mixed with other metals and the purity is very low.
Step 3:
Hold a magnet near the piece of gold. If the magnet attracts the gold piece, then there are other metals mixed in the gold. This is not pure gold.
Step 4:
Purchase hydrochloric acid or sulfuric acid, rubber gloves, and protective eyewear from a hardware store. Use something like a small piece of glass to drop a very small amount of acid onto the gold. If the gold begins to dissolve, then there is some other type of metal mixed with the gold and it is not pure.
