Review on 💎 Diamond Tester Pen: WECHIC High-precision Professional Jeweler Diamond Tester for Novices and Experts by Hannah Curi

Ordered and first worked once ringside and nothing else. Put the ring back on and it doesn't work there either. Sent it back and chose another one assuming the first one was bad. The second came and it doesn't read anything I touch. Whether something is glass or not diamond is at least slightly emphasized in the video. The only time I get a reading at all is when I touch the metal sides, which I only do to see if something is working. I am now returning a second one for a full refund but unfortunately nothing will replace the time I wasted on this.
