The Deluxe Hardness Pick Set from Mineralab is unique in that, unlike other mineral hardness testing tools that use minerals or crystal points for the "scratch test", Mineralab’s picks are made of metals and alloys of hardness values equal to 2 through 9 on Mohs’ hardness scale. And because the picks are made of metal, they are easily ground to sharp points which will not break off and which can be easily sharpened.
Why measure the hardness of a mineral? Because hardness is an important and quantifiable physical characteristic of a mineral, and in your effort to identify an unknown mineral, the hardness, if known, combined with other properties, can narrow your search to just a handful of possibilities.
How do you use the hardness picks? Simply scratch a smooth surface of your unknown mineral with the picks of various indicated hardness. As an example, if a No. 5 pick scratches the mineral, but a No. 4 pick does not, then your mineral’s hardness is 4.5. Then compare this against the included table of minerals listing hardness values to aid in identifying the unknown mineral.

The Mohs Hardness Testing kit arrived quickly especially as it was posted from USA to Australia. It arrived exactly as described and I have already used it to help identify an unfamiliar rock. I would recommend Mineralab to other rock hounds and I will definitely use the supplier again. Terry Nesbitt on Jul 1st 2021

I have been using them they work great Ronald P Alexander on Dec 23rd 2019
Never make do with make do tools again. These picks let you test different minerals in different parts of a rock with certainty and ease. No more trying to scratch something with a penny or a knife, no more guessing. This is the second set I’ve bought, this one as a gift for a young university geology student. No one regrets buying good tools. These are _great_ tools. Thomas Farley on Oct 2nd 2019

jeologlar ve gemologlar için çok gerekli bir ürün. teşekkür ederim (A very necessary product for geologists and gemologists. thank you) Ayşe KIZILKAYA on Mar 7th 2019
We just received our order, the quality of the workmanship is exceptional. this is the best looking tool in my shop. high quality workmanship, we recommend to everyone wanting to know more about the hardness of the stones. The hardness stone directory chart for most common minerals is a must appreciated bonus.

I first heard of this from a friend who has had one for some time. He uses it frequently and says it is a standard for mineral id. I haven't had a chance to use it yet but I will soon. Ron Bice on May 15th 2017
