wikiHow had several different ways to test. Some of the the methods needed scientific equipment, so I ruled them for my informal experiment. I decided to use the streak test. I rubbed the pieces of jewelry across an unglazed porcelain tile (which I had in the backyard from an unfinished craft project). wikiHow said that if the jewelry left a black streak then it wasn't gold, and if the streak was golden yellow I had real gold.
I took a handful of jewelry outside and started rubbing. Much to my amazement, I DID get different color streaks from different pieces!
These were not gold:
- My college ring (I knew this wasn't real; I never would have paid for the real thing)
- A garnet ring from my mother-in-law
- An opal ring from my mom
- My Dad's wedding ring
- An old cocktail ring from Mom
- A bracelet marked 14k on the inside (yes, I threw in a ringer for verification)
