Great for figuring out diamond jewelry
Works really well at detecting real diamonds from fake diamonds which makes it a great value for the money and very easy to use and it's very accurate and is a size that most hands can hold

Wonderfully simple
Inherited some jewelry and not sure if precious gems or not. Tested gave me the answers and saved me the expense and trouble of going to a jeweler

Works Great But Came With Dead Battery
It took a bit of trial and error and re-reading the detailed instructions to get it to work. But once we figured it out, it's very easy to use. The one main complaint is a minor one: the battery that came with the Diamond Tester died after just a few minutes of use. Fortunately, it's a common battery (9V) and we have spares, so we were able to get it up and running again. Despite the challenges, it seems to work well and is reasonably priced.

Works well :)
Nice little tester ! It’s pretty light weight and fairly quick. And it fits in my purse without taking too much space. I was able to go through a few pieces that where given to me over the years and compare it with an older tester I have and it read the stones correctly . I tend to go to estate sales so these come in handy :)

find a better option
fix the battery holder damnit, a bunch of reviews are saying this and the instructions are bare minimum but I figured it out. I wouldn't consider it the best there is no secure place to put the battery. it legit has no secure holder the connectors are loosely just sitting inside as you see in other review photos. I at first assumed it got that in shipping but... WRONG it arrives this way naturally with no damage to packaging. soon as you place the battery in the unit will lose power soon as the battery shifts out of position of the connectors due to it having no placement in the area whatsoever. you just place the battery in and angle it right enough for the lights to stay on. as far as accuracy it definitely can tell glass from diamond and moissanite. it definitely feels cheaply made like you could drop it and it'll break or step on it accidentally and break. due to the battery situation the functionality is lacking and I feel like you could just find better value for your buck where quality of the consumer is put in the front.

Aquí tienes una reseña lista para publicar 😊 ⭐️⭐️⭐️⭐️⭐️ Muy práctico y fácil de usar Este probador de diamantes es muy útil y funciona perfectamente. Es fácil de usar, solo se enciende y en segundos indica si la piedra es real o no. Las luces LED son claras y fáciles de entender, incluso para personas sin experiencia en joyería. El tamaño es compacto, ideal para llevar o guardar sin ocupar espacio. El material se siente resistente y llegó bien empacado. Excelente relación calidad-precio, totalmente recomendado para uso personal o como herramienta básica de joyería. 💎✨
