This method is best used on scrap gold to be smelted due to the destructive nature of the testing, but can be used on gold pieces to be worn if the testing if done in an inconspicuous spot. PLEASE NOTE: Gold testing acids are made using NITRIC ACID that can harm the skin. Please exercise caution when using this method of testing, including proper protective eye wear and gloves. Nitric Acid can burn the skin and leave stains. This silver neodymium N52 rare earth magnet is perfect for preliminary gold, silver & platinum testing before using test acids or another method. Precious metals are not magnetic, therefore this magnet should not pull anything that is true, genuine gold, silver, or platinum. This method is not 100% accurate, as this will pull pieces that are gold plated and there are certain types of steel, copper, and similar metals that are not magnetic. This is best used as a preliminary test in conjunction with test acids or a gold tester or to verify the hallmark.To use, simply place the magnet near the piece you are testing. If a non-precious metal is detected, the piece will be pulled toward the magnet. Precious metals are not magnetic and pure precious metals should not be pulled toward the magnet. Procedures for Testing Gold, Platinum and Silver:To test for the karat value of gold, platinum and silver, you will need the following materials and tools:Black acid testing stone that is washed thoroughly with water prior to each test OR a needle fileAcidsReference Gold - Either Gold Testing Needles or Verified Gold Pieces Testing for 10K, 12K and 14K:Scratch or Rub the piece onto the test stone, leaving a visible deposit of gold on the stone. Next to this position, scratch the appropriate needle (10, 12, or 14K) - if you do not have needles you can use a gold item that has a known karat value. Place a drop of the appropriate acid (same solution as the needle/gold item you have used) on the stone where the gold deposits are. If the gold is the same karat or higher, the acid will not affect the gold marks. If the gold piece is of a lower karat, the scratched deposit will dissolve and eventually disappear while the mark from the needle will stay. When testing for potential gold plated items such as heavy necklaces and earrings, use a metal file to make a slight gouge in the piece. Place a drop of acid (the acid should match the karat value of the gold on the piece) onto the gouge. If the item is gold-plated, the acid will slowly dissolve the metal underneath. If the item is pure gold, no reaction should occur.By repeated trial, the karat of the gold pieces can be determined to a close approximation.(Caution: Many objects are marked 14K, but were fabricated prior to 1982 when it was legal to mark items 14K, but in reality the gold was 13.5K When testing 13.5K gold the 14K solution will not dissolve the scratch, but will make it lose its brightness and will turn it into a yellow-rusty color) Testing for 18KRepeat the steps from above and apply 18K acid. Any gold that is less than 18K will disappear in less than 30 seconds. Gold that remains on the stone is 18K or higher. Testing for 20K and 24KRepeat the steps from above. Apply one drop of 22K acid to area. The material that starts to disappear first has a lower karat value (20K), while the gold that stays is 22K-24K gold. Testing for PlatinumScratch the test piece on the stone and apply one drop of Platinum Testing Acid to the application on the stone. If the material is platinum, it should keep it's white, bright color. Testing for White GoldThe same procedure and Testing Acid for platinum can be used for 18K white gold . The material on the stone should start changing to a light bronze color in about three minutes. For 14K white gold, the material on the stone should disappear in 15 seconds. Testing For SilverPlace a drop of acid on the object to be tested. 90 to 100% silver, the acid will show a creamy color. 77-90% silver, the acid turns a gray color.65-75% silver, then the acid will show a light green color.
