  • Mineral Hardness Scale Ruler

    The Mineral Hardness Ruler is a stimulating visual aid, educates in one phase of mineralogy, and provides the standard ruler measurement scales needed in classes.


    Rockhounds, mineral enthusiasts, students, teachers, geologists, and any one interested in rocks and minerals will find the Mineral Hardness Ruler a handy visual aid for quick information on mineral hardness.



    The two-sided, flexible, glossy, vinyl ruler consists of five scales: three measurement scales and two mineral hardness scales. The measurement scales are in standard ruler measurements of tenths of inches, sixteenths of inches, and millimeters. Mohs' relative hardness numbers are integrated into the inch scales, while a separate scale exists for an absolute mineral hardness scale by Rosiwal.


    On one side of the ruler are pictures of the ten common minerals, in full color, selected by Mohs for his relative hardness scale. On the reverse side of the ruler are six common items with their relative hardnesses. These items, along with known minerals, can be used as a handy field kit to test the relative hardness of an unknown mineral.


    Hardness is one property of a mineral that can be used to distinguish among similar minerals. A given mineral can scratch any other mineral of the same or softer hardness. Over a hundred years ago, the German mineralogist Frederick Mohs devised the relative hardness scale that has found favor with mineralogists for over a century. Others, such as Rosiwal, formed absolute hardness scales using the same minerals as Mohs. For example, diamond, the hardest substance in Nature is not twice as hard as apatite, 10 versus 5, but over twenty thousand times as hard, 140,000 versus 6.5.

  • Lanyard, Plain Black, 3/4in Nylon, with Quick Release Buckle and Split Ring

    Lanyard, Plain Black, 3/4in Nylon, with Quick Release Buckle and Split Ring

    Heavy duty 3/4'' plain black nylon loupe lanyard with a quick release buckle and a split ring. This lanyard may be used for any purpose but we've had it custom manufactured specifically for use with the BelOMO loupe.

    Important: We offer this lanyard for no additional charge when you buy the combo package of the BelOMO loupe with attached lanyard. Attaching the lanyard requires a screw to be removed so let us do it. We've been doing it for years and you save money!

    Use the split ring on loupes with a mounting hook. To use the lanyard with a BelOMO loupe remove one screw on the support shaft of your BelOMO loupe, swivel the frame out of the way and slide the end over the support shaft then install the screw again. Don't use the split ring to attach the lanyard to the loupe. (We suggest that you purchase the loupe with the lanyard already installed.)

  • Deluxe Moh's Mineral Hardness Pick Set

    The Deluxe Moh's Hardness Pick Set now comes in two case types. The wooden case is small enough to carry and the top screws into the base to make a perfect desk stand. The plastic case is longer but the thinner size makes it easier to carry in your field tool set.

    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 Mohs' 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.

    What is included in the Mineralab's Deluxe Mohs' 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 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.

    • Complete usage instructions.


    Other Features:

    • All points are stamped with the indicated hardness value, and each double-ended
      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.

    • Compact. The wooden storage case is only 7" tall by 2.5" wide.

    • Also use to test hardness of various materials encountered in the industrial,
      excavation, and archeological fields.

    • 1 Year Warranty
    If you are ordering only a Deluxe Moh's Hardness Pick Set you can save money on shipping by choosing USPS Priority Mail. We will use a USPS Priority Mail Small Flat Rate Box and I'll adjust your total to pass the savings back to you.
