Gemtone Gold Testing Kit, 10K 14K 18K Testing Solutions with Stone, Professional Jewelry Purity Test Set, USA

Great kit good value works as it should.

A pretty easy and reliable testing kit. It comes with instructions but you can go online and find the testing process as well. So far, I tested it on known true gold and known fake costume jewelry and it was accurate every time. The testing stone is pretty small, so you will have to ensure it's always clean or purchase a separate one. The biggest upside is the amount of testing fluid included. If you compare this kit to many others, this one has enough fluid for many tests. Others were noted to include enough fluid for 3-4 tests at maximum.

Works great!!! Very easy to use and very accurate!!

La verdad ahora voy más tranquilo y confiado cuando quiero comprar algo de oro. Excelwnte kit de prueba para no ser víctima de los estafadores

El único detalle, la piedra venia partida en una esquina

It was accurate on everything that I tested, which was 10 karat and 14 karat gold.

Works great! The stone is quite small but other than that, the test kit worked well!

My gold testing kit was a disaster not accurate for 14 Kt turned brown and the 18 Kt not working well So for long years I work with precious metal and it time not was good my Testing Key I’m Used it brand before without any issue
