stones hardness rating

One vital factor in measuring gemstone resilience is hardness. In gemology, a stone's hardness is gauged on a scale called the Mohs Scale, which 

This is my little kit, the stones do not wear out and their composition and hardness ratings are universal. The stone hardness doesn’t seem to be a factor, the type of steel is a factor. Shapton likely know the answer, the HR Glass stones were designed to cut the wear-resistant, semi-stainless Lie-Nielsen A2 plane steel, so they know what

Gemstone hardness – Mohs scale of mineral hardness ; 7, Quartz, 100 ; 8, Topaz, 200 ; 9, Corundum (Rubies and Sapphires), 400 ; 10, Diamond, 1600 

Surprisingly, quartz has an absolute hardness 100 rating. Compare that to diamonds, with an absolute hardness of 1,500, and you can see how hard quartz really is. Quartz is a popular choice partly because of its hardness, and partly because it's virtually maintenance free. However, some homeowners prefer the looks of other stones.

Hardness is a measure of how resistant a crystal is to being scratched. The Mohs hardness scale is one method for classifying hardness, with stones rated from one (softest) to

Mohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812)

The Mohs Hardness Scale was developed by German mineralogist, Friedrich Mohs in 1812. The scale consists of 10 readily available minerals of particular hardness

In the beginning, I wanted to try and portray hardness, fineness, and speed. I later discovered that all fall under the hardness of the stone, and hardness was the most important thing to look for. So you will only see a level of hardness listed with any stone on my website. The hardness levels range from Lv1-Lv5+, softest to hardest, respectively.
