Set of 4 Gold Silver Platinum Jewelry Tester Scratch Streak Stones to use with Acid Test Kits 10K 14K 18K 22K 24K Minerals Precious Metals Detector

Love this. Had to order more because I put them in a tote or bag and never found them again

Works good

These items have revealed some great finds! Well worth the money

These plates are absolute garbage. Complete false advertising, showing pictures of scratch stones with pure black and pure white surfaces. They are pretending to be the nice ceramic scratch plates that are solid black or white... what you actually get is cheap greenish frosted glass with a black or white sticker on the bottom. Not only that, they barely work. It's almost impossible to get any sterling or gold to scratch onto these since the surface is too smooth. Anything that does get on there simply floats to the surface when you add the testing acid and gives you false negative results. Utter trash and a complete waste of money.

Great loupe at a great price! Great size for beginners!
