Skala twardości Mohsa − dziesięciostopniowa skala twardości minerałów charakteryzująca odporność na zarysowania materiałów twardszych przez materiały bardziej miękkie. Została stworzona w 1812 roku przez niemieckiego mineraloga Friedricha Mohsa.Twardość poszczególnych minerałów nie jest ułożona proporcjonalnie i liniowo, lecz ma charakter porównawczy.

Jul 05, 2019· Gemstone hardness is one of the primary factors when making this comprehensive determination of wearability. For example, gemstones such as opal (Mohs 5.5 - 6.5), moonstone (Mohs 6 - 6.5) and pearl (2.5 - 4.5), are considered to have poor wearbility and should, therefore, be worn in earrings and pendants. If you have your heart set on wearing a ...

L'échelle de Mohs fut inventée en 1812 par le minéralogiste allemand Friedrich Mohs afin de mesurer la dureté des minéraux. Elle est basée sur dix minéraux facilement disponibles, classés du plus tendre au plus dur. Comme c'est une échelle ordinale, on doit procéder par comparaison (capacité de l'un à rayer l'autre) avec deux autres minéraux dont on connaît déjà la dureté.
