Just doesn’t grab precious metal. Cheap but kind of useless

The Gemtone Scratch Testing Stone sets a new standard for precision and reliability in metal testing. While this product includes only the testing stone itself, its exceptional performance outshines competitors, making it a must-have tool for anyone working with silver, gold, and other precious metals.One of the standout features of this testing stone is its black color. Unlike traditional white or light-colored stones, the black surface enhances visibility and readability of test results, making the testing process more efficient and accurate. This simple yet effective design choice significantly improves the user experience.Measuring 6â€x3â€, the testing stone offers a generous surface area for conducting tests on various metals, while remaining portable enough for on-the-go use. Whether you're in the workshop or out in the field, this testing stone provides the versatility you need to conduct tests with ease.Durability is another key advantage of the Gemtone Scratch Testing Stone. Constructed from solid materials, it feels sturdy and reliable in hand. The addition of a rubber anti-slip backing not only enhances grip but also contributes to the product's longevity, ensuring it withstands frequent use over time.Having tried other testing stones in the past, I can confidently say that the Gemtone Scratch Testing Stone surpasses them all. Its superior design, visibility, portability, and durability make it the go-to choice for professionals and hobbyists alike. If you're serious about metal testing, invest in the Gemtone Scratch Testing Stone for accurate results every time.

It's good value for the money but it's a glass stone that dolls really quick after several uses

Useless without acid to color the stone. When I read the information it said nothing about not coming without the acid and I guess I am too new to the testing process to understand that it was necessary until I received the stones and then received this information.

Well a some what very expensive item in comparison to other sellers .I assume d this would include acids for doing test s,after trying to find out via Rufus .I was unable to get info I wanted .the advert info is a bit confusing .no instructions as advised on the item itself were included.abd any acids have to be ordered separately ,and a hefty delivery charge on the top of the purchase .I'm sure the other less expensive stone will do the job.sirley they all do the same.some acids don't guarantee English instructions???? So I'm not too happy so far.but will update of any thing else I've found .good luck ???
