A gold testing kit with a testing stone is a commonly used tool for assessing the authenticity and purity of gold. This kit includes a testing stone made of black slate and a set of acid solutions of varying strengths to distinguish between the purity of 10K, 14K, 18K, and 22K. Silver and Platinum metals 

To use the kit, you would typically rub the gold item against the testing stone to create a streak or mark. Then, you would apply the acid solutions to the mark and observe the reaction. The acid solutions are designed to react differently depending on the purity of the gold.

For example, if the gold is genuine and of high purity, it will not react or show any discoloration when the acid is applied. However, if the gold is of lower purity or contains other metals, it may react and show discoloration or fading.

The specific acid solutions provided in the kit may vary, but they commonly include acids like nitric acid or aqua regia. It is important to follow the instructions provided with the kit and take necessary safety precautions when handling acids.
