See below for silver and gold testing instructions!
How to Test (Gold): Scratch the metal in question onto testing stone; be sure the testing stone is clean and free of any other materials. Once you have a visible line to work with, place a small drop of the closest acid solution to the karat you estimate the metal might be. If the acid solution dissolves the metal, the metal is LESS than the karat that is displayed on the acid testing solution bottle. If the metal sample stays and does not dissolve, it is at least the karat of the acid testing solution used or possibly higher.
How to Test (Silver): Scratch the metal in question onto the testing stone; be sure the testing stone is clean and free of any other materials. Once you have a visible line to work with, place a small drop of the silver testing solution and look for one of the following results: Dark Red = 90-100% Purity; Light Red or Brown = 80%-90% Purity; Light Green = 65%-75% Purity; Creamy white results can indicate that the item is sterling silver; lastly, green results can indicate that the item is silver plated.
Incredibly lightweight and compact, the ToolTreaux 6pc silver and gold testing kit is great for on the go testing or travel if needed. Suitable for those in jewelry sales and appraisal, jewelry making and design, to include with gold prospecting equipment and gold panning kits and more.
