A scale developed by Friedrich Mohs to determine the relative hardness of minerals and other objects. The scale assigns the numbers 1 to 10 to specific minerals, softest to hardest respectively, using a scratch test.
A list of ten minerals in a sequence of relative hardness, with which other minerals can be compared.
A sequence of 10 common minerals arranged according to their ability to scratch each other
A collection of minerals ranging from very soft to very hard. Use as a comparison scale during mineral identification. From softest to hardest, the ten minerals are: talc 1, gypsum 2, calcite 3, fluorite 4, apatite 5, orthoclase 6, quartz 7, topaz 8, corundum 9, and diamond 10. Developed by Friedrich Mohs, a German mineralogist in the early 1800's.
A scale developed by Friedrich Mohs to quantify the hardness of minerals and gemstones. It utilizes a scratch test to rate diamonds on a scale of 1-10 (the higher the number, the harder the mineral will be).
The Mohs Hardness scale is a scale that ranges from 1-10 in measuring a gems hardness (resistance to scratching). Ten is considered the hardest point and ranges down to the softer gems. Mohs scale is not an equal scale. The different hardness between one gem to another is not necessarily equal to that measurement. For example, a diamond (10) is many times harder than a ruby (9). The following is the scale in relation to the gem species. 10- Diamond (one of the hardest known substances in the world 09- Corundum (ruby, sapphire) 08- Topaz (blue, yellow topaz) 07- Quartz (smoky, rose quartz) 06- Orthoclase (sunstone) 05- Apatite 04- Flourite 03- Calcite 02- Gypsum 01- Talc
Numerical scale ranging from 1 to 10 developed by Friedrich Mohs that assigns a rating to a gem according to its ability to resist scratching. The hardest is 10 (diamond) and the softest is 1 (talc).
A scale of relevant Hardness, where 10 is the hardest and 1 is the softest. The Diamond ranks 10 on the Mohs Scale.
