Description

Gold Testing Needles for determining 8k, 10k, 12k and 14k gold karat values

To successfully complete the steps to determine gold karat values, it is necessary to have:

Gold testing needles

Gold testing acids

Testing stones

First step: The testing stone has to be thoroughly cleaned with test acid neutralizers. Using water to wash the testing stones is not as accurate.
Second step: Scratch the gold piece, which needs to be tested, on the testing stone.
Third step: Next to the place where the gold piece was rubbed, scratch the suitable testing needle (8k, 10k, 12k, 14k).
Fourth step: Place a drop of the matching testing acid (8k, 10k, 12k, 14k) on the testing stone where the gold was scratched.
Reading the results: If the color of the scratch spot for the gold piece turns out to be the same as the color left from the mark of the testing needle, then the gold tested has the same karat or higher. If the color becomes faded and eventually disappears, then the gold has a lower karat value.
