Product Description

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. 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 hardness is 4.5. Then compare this against a table of minerals listing hardness values to aid in identifying the unknown mineral. The Deluxe Hardness Pick Set from Mineralab is unique in that, unlike other mineral hardness test tool that use minerals or crystal points, Mineralab picks are made of metals and alloys of hardness values equal to 2 through 9 on Mohs hardness scale. 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. Included in the Mineralab's Deluxe Hardness Pick Set: * Four double-ended picks with eight points comprising 2 and 3, 4 and 5, 6 and 7, 8 and 9 on Mohs' hardness scale. * High quality brass pinch vises. * A glass plate (hardness of about 5.5) which, when scratched, quickly distinguishes hard from soft minerals. * A second hardness plate with a hardness value of 3 5. * A white streak plate for testing a mineral's streak color. * A magnet to test magnetic rocks such as magnetite and pyrrhotite. * A 100 grit polishing stone to keep the points sharp. * An attractive, mahogany-finished and compact wooden case. * Hardness Table for 300 minerals * Complete usage instructions. Other Features: * All points are stamped with the indicated hardness value, and the pick body is color coded for quickly finding the desired pick. * Hardness points can be easily and inexpensively replaced without having to replace the pick bodies. * 1 year warranty.

Deluxe Mohs' Hardness Pick Set for Mineral Identification Review

This Mohs' harndess pick set is made by Mineral Lab. The picture looks much bigger than the real set itself. You can get it cheaper here at Amazon.com than from Mineral Lab. Postage is a little bit stiff for such a small set. Comes with four metal pens with two hardness picks on each end (i.e. 2 & 3; 4 & 5; 6 & 7; 8 & 9). The 2 & 3 and 8 & 9 are almost worthless since I use mostly the middle two. Not the easy things to use. You have to keep the pick sharp and then you really have to press down to test the stones. Also, the numbers on the picks are difficult to read. I kept getting confused the 4 with the 7. You can almost buy one set and make it into two sets by purchasing extra replacement points from Mineral Lab and then turning them into two sets. The customer service of Amateur Geologist was extremely helpful but that of Mineral Lab was not quite as friendly. Is it really worth the money? It is really hard to say. I think it should sell at around the $ 45 to % 50 range. Also, the sharpener comes with the kit is way too small. However, this is the only hardness pick set available in the States.
