The Mohs Scale – A List of Gemstone Hardness

Asaf Levy 26 Jul 2020

It’s often said that there’s nothing harder than a diamond, and we are often asked if a diamond is used to cut another diamond (the answer is yes)… But have you ever wondered how we know this? The answer is simple – the Mohs scale of hardness.

In 1812, Friedrich Mohs – famous geologist and mineralogist created a scale of mineral hardness grading from the softest (1) to the hardest (10). The scale was created using the simple technique of one mineral’s ability to visibly scratch another.

The softest mineral that features on the scale is Talc at 1, and everyday objects of hardness such as pencil lead (1.5), finger nails (2.5) and window glass (5.5) can help you get a true value of the scale.

We’ve taken a list of some of the most popular gemstones that are used in jewelry (some of which you’ll find on our website) to help you see the hardness of your favorite.

Gem Hardness
Diamond 10
Ruby 9
Sapphire 9
Chrysoberyl 8.5
Topaz 8
Spinel 8
Emerald 7.5 – 8
Aquamarine 7.5 – 8
Morganite 7.5 – 8
Amethyst 7
Quartz 7
Tourmaline 7 – 7.5
Citrine 7
Tanzanite 6.5 – 7
Peridot 6.5 – 7
Jasper 6.5 – 7
Tiger’s Eye 6.5 – 7
Zircon 6.5 – 7.5
Bloodstone 6.5 – 7
Onyx 6.5 – 7
Moonstone 6 – 6.5
Opal 5.5 – 6.5
Lapis Lazuli 5 – 6
Turquoise 5 – 6
Malachite 3.5 – 4
Coral 3 – 4
Pearl 2.5 – 4.5
Amber 2 – 2.5

Whilst this scale is a guide to mineral hardness, it does not always factor in other elements of a gemstones structure when you are considering stones for day to day wear. Emeralds for example are well documented as having many inclusions within the stone, these can often weaken the structure and make them more susceptible to scratching and even chipping – and some styles are not suitable for everyday wear. Citrines, however, are not recommended to come into contact with heat as they can fracture.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
