You can check the official symbol of gold, which is generally engraved with 999 or 990, or 10K, 18K, 22K, 24K. Anything below 10K is not considered, because the gold content is too low. Of course, fake gold ornaments will also have official signs, so further inspection is needed.
You can check the worn area of gold surface, usually at the edge of gold products, and check the discoloration there. If the gold gradually disappears and becomes another color, then the product is only gilded.
