Lapis Lazuli Rough

Another science question?

What is a mineral's hardness?
How do we use Moh's scale of hardness?
Please answer

Moh's Scale Is Still Used in Mineralogy & Gemmology
Crude but Practical

In 1822, Friedrich Moh, a German mineralogist devised a crude but practical method of comparing hardness or scratch resistance of minerals. It has become universally known as Moh's scale or Mohs scale as the grammatically challenged would call it.

Comparative not Scalar
It should more accurately be called a table, because it is not to scale, that is the numbers allocated to different minerals are not proportional to their actual scratch resistance, so that the scale is really an ordered list.

Starting From Scratch
Moh took ten well known, easily available minerals, and arranged them in order of their "scratch hardness".
If a specimen to be tested can be scratched by a known mineral from the list, it is softer than that mineral. If it in turn will scratch another known mineral, it is harder than that mineral. This gives a very quick and easy field test for hardness. As such is it very useful for mineralogists. It is too destructive to be commonly used in gemmology, but is available, and can be valuable on Rough Gemstones.

Don't Try This At Home
A crude form gets used on shop windows by people testing out their diamond rings, in the mistaken belief that only diamond will scratch glass.

Measures of Hardness
There are many different aspects of materials which could be considered as a measure of hardness. Hardness can mean resistance to scratching, indentation, bending, breaking, abrasion, cleavage, or fracture. It is easy to confuse durability or toughness with hardness.

A very simple example is to consider a glass ball and a rubber ball. Glass is harder than rubber, but rubber is more durable. Try bouncing both on a hard floor, the glass ball will shatter, whereas the rubber ball will bounce.

The aspect of hardness which is measured by Moh's test is the scratchability of a mineral.

Other Scales
Other scales of hardness include Brinell's Vicker's, Knoop, Meyer, Rockwell, and a rebound (dynamic or absolute hardness) test measured with a sclerometer.

The hardness of each mineral relative to the others varies according to which test is performed, and also hardness can vary according to the grain direction, or crystallographic orientation, of the specimen. We have given typical Brinell hardness figures for each of the minerals in the table. Diamond's hardness cannot be measured on the Brinell scale, because a diamond indenter is used for the test itself, but it is many times harder than corundum.

Sapphire and Ruby are the well known varieties of corundum.
Amethyst, citrine, rock crystal, and cairngorm are all varieties of quartz.

Importance for Gemstones
Generally, high scratch resistance is desirable for gemstones, and a Moh's hardness of 7 or higher is important. The principal reason is that a common cause of abrasion is sand, which is silica grit (quartz), and is commonly present in dust. Stones which are softer than quartz are not suitable for everyday use as facetted jewellery gemstones, particularly in rings, although many are beautiful and attractive.

Some gems, such as pearls, Coral, turquoise, lapis lazuli, amber, and Opal are quite soft, but are usually polished into cabochons or beads, rather than facetted, and therefore do not show scratches so easily. All these gemstones have been successfully used in jewellery for many centuries.

Harder than Diamond: It surprises most people to learn that things exist which are harder than diamond.
