Product Description
The Hardness Pick Set for Mineralab ID 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.
What is included in the Hardness Pick Set?

Four double-ended picks, color-coded, with eight points comprising 2,3,4,5,6,7,8, and 9 on Mohs’ hardness scale, as shown above.

Not what I wanted but Excellent quality
I wanted the Deluxe harness kit. After the order was placed, a representative called me to say that they did not have the kit with the wooden block. Only the kit in the plastic case. I agreed to take that. The hardness picks are good. Mark Cox on Aug 15th 2024

Great product
Just got into rockhounding and searched everywhere for the best hardness tester. Every person I spoke to recommended the Deluxe Hardness Pick Set from Mineral Lab. Received the set and was not disappointed. Quality product. I would recommend this set to anyone looking for a hardness pick set. The set I bought came in a wood case, the lid to the wood case once removed can be screwed to the back to support the set to keep it upright. They also have a set in a sturdy plastic case if you need to have a more rugged case for out in the field. Paul R. on Feb 20th 2024

All in one, easy to use and maintain
Straightforward simple to use easy to understand. Found a unique feature accidentally. While testing a gemstone that had a chipped culet, the color treatment scratched at 7, well before the stone scratched. When I refaceted the culet I found a clear stone at 8.5 not a pink one!

Quality product!
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

Indispensable Product
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

Highest quality Hardness kit on the market
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.

Mohs hardness tester for Mineral identification.
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
