At home density test - Specific Gravity
At home density test - Specific Gravity
Dry weight / Submerged Weight = Specific Gravity
The home version isn’t perfect, but it would catch many of the common metal fakes.
A 0.01g string error puts this at a 10.494
Fun to play with and kind of magical that someone thought of this.
Always best to use multiple testing methods.

Any difference in sound is a strong indication that further testing is needed. Always use multiple testing methods.
