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.

All new design for the lanyard. The lanyard can now be install and removed without tools.
Softer design with double sided logo. Most lanyards have the logo on one side only.
We sell a lot of loupes to customers who have lost their loupe in the field. Using a lanyard keeps the loupe handy and with you rather than sitting near that last rock you examined. Now.... where was that?
Here is a heavy duty 3/4" nylon loupe lanyard with a quick release buckle. Disconnect the buckle when you don't need the neck lanyard. But don't set the loupe down and walk way!
This lanyard may be used for any purpose but we've had it custom manufactured specifically for use with the BelOMO loupe. Open the buckle to remove and swing the BelOMO loupe open to remove to lanyard. Open the buckle, swing the loupe open, slip the the long side of the buckle around the post, close the buckle and close the loupe and the lanyard is installed.<
