Mineralab manufactures two different versions of our Mohs' Hardness testing tool:

  1. Our original Deluxe Hardness Pick Set and Mineral Identification Kit geared toward rockhounds, mineral enthusiasts, and science teachers, and
  2. Our Mohs' Hardness Test Kit for Industrial Applications customized for industrial uses such as Concrete Hardness Testing, and for scratch testing of other industrial materials.

Currently, we are out of stock on both versions because of pandemic-related supply chain issues for some of the raw materials we use in manufacturing.  Our best estimate of re-supply is mid June.  You can pre-order here if you like, which fixes your place in line.
