Q: Does it test non flat items such as jewellery

No. At least you need a 3mm diameter measuring place

Q: What percentage level of confidence does this device give for differentiation of 999,925,916 gold coins

How the measurement works: A. Soundvelocity known 1. Enter the sound velocity of the material to be tested into the device, e.g. Gold 999 2. The device outputs a value for the thickness of the measured test piece during the measurement, e.g. 3mm 3. If the measured value (in this case: 3 mm) matches the actual thickness of the test object, the test object is made of the set material (here: Gold 999) Sound velocities can be found in our tutorial and can be found on Google or Wikipedia. B. Soundvelocity unknown 1. Test a specimen of known material e.g. 925 silver 2. Determine the soundvelocity by changing it until the thickness indicated on the unit matches the actual thickness of the sample, e.g. 2mm 3. Now you have the soundvelocity of silver 925 and you can test more specimens on silver 925.
