Scratch the piece to be tested over the surface of atesting stone press firmly, leaving a visible deposit,preferably a line 1'' long.2. Add a drop of the 10K solution to the scratched area.If the solution dissolves the scratch on the stone, theobject is less than 10K gold or not gold at all. If thesolution leaves the scratch intact, the object is 10Kgold or greater than 10K gold.3. Repeat the scratching and testing with the 14Ksolution. If the solution dissolves the scratch on thestone, the object is less than 14K gold (if the scratchdissolves slowly and leaves rusty color particles, it isprobably 12K gold). If the solution leaves the scratchintact, the object is 14K gold or greater than 14K.CAUTION: Many objects are marked 14K, but werefabricated prior to 1982 when it was legal to markitems 14K, but in reality, the gold was 13.5K. Whentesting 13.5K gold, the 14K solution will not dissolvethe scratch, but it will make the scratch lose itsbrightness, making it turn a yellow-rusty color.4. Repeat the scratching and testing with the 18K and22K solutions (if available) to determine the karat ofthe object. When the solution dissolves the scratchslowly and leaves rusty color particles, the testedpiece is probably two karats lower than the solutionbeing used. For accurate testing, we recommend thatthe user becomes familiar with comparative testingusing standard gold testing needles.Note: Heavyweight items such as chains and coins maybe plated. Make a deep notch in the piece and performtesting on the metal inside.TESTING FOR SILVERSimply scratch the test stone with your jewelry and apply a drop of the silver acid solution to the stone and watch the results appear! The color reaction of the solution on the jewelry will be as follows:90%-100%= Creamy color77%-90% = Gray color65%-75% = Light Green colorTESTING FOR PLATINUM AND WHITE GOLDTransfer a drop of the platinum test solution to the jewelry. If the area stays a white, bright color, it is real Platinum. Platinum test liquid can also be used for 18k and 14K white gold. In the case of 18K, the solution on the jewelry should start changing to a light bronze color in about 3 minutes. For 14K white gold, the solution on thejewelry should disappear in about 15 seconds!If you have any further questions, please feel free to contact us.
