Review on 💎 Gemoro Testerossa Diamond, Moissanite, Sapphire Bead Jewelry Making Kit by Kelly Caballes

. The Diamond tester worked perfectly. I found him to be very reliable and tested all types of jewelry with him, only once did he find moissanite. This was probably because there was oil on the diamond. Make sure the diamond and tester tip are clean. The tester's tip is also spring-loaded, making it more durable and less likely to bend when the tip is pressed firmly against the diamond. Very comfortable in the hand. Supplied with rechargeable batteries that were dead on arrival and a base to recharge the batteries. The first tests I put in 3 regular AAA batteries and they worked fine, then I put the batteries in, charged them on the base station and they worked fine too. The tester's voice is clear, precise and understandable. With the tester you have both voice and visual recognition. During the test, one of the 4 LEDs also lights up. Green for diamond, blue for moissanite, pink for sapphire and red for metal contact. It comes with a pre-program in English, but other languages can also be programmed. I made this purchase on Amazon and it took about 3 days for shipping.
