Watch out for all the red flags. Hand stamped, no stamp, no manufacturer trademark, tests 14 and then 10 and then 18 depending where you test it. Also, real karat gold can falsely test higher if it has a finish on it. Known 10K will test in the low 14K, for example, but once you gently clean a skinny area, it will test correctly. This is also true with 14 that will test 18 and with 18 that will test 22. Beware of the higher karat finish used by manufacturers. Once you clean the area with the pumice, it will test correctly.
Always stand the item up (never lay it flat) and test the gently cleaned skinny area that is facing up toward you.
Find a skinny, edge, opening, etc where the plating wears away fastest and always file that area to test, or if it's not a heavy piece, gently clean the area with the pumice attached to the pen cap, and then test so it gives you proper reading (see my Top 5 Testing Tips)
Sadly, even Spectrometers (Xray machines) will test gold plate as real unless you file into it. Your diluted karat acid will test gold plate as real. Actually, KEE has caught the non-gold that our spectrometers and diluted acid misses. You need to follow my Top 5 Testing Tips. KEE is very accurate, more accurate than diluted acid, and by far more accurate than any other electronic gold tester. Your best bet is to go on JHJ and do a keyword search, KEE Tester; you'll be able to see what thousands of pawn shops and jewelers have experienced with SHR's KEE. Watch my videos; review the gold plated and gold filled testing QuickKEE video.
