Some gemstones withstand everyday wear, while others crack at the slightest touch. Some are delicate while others are strong. But how do we differentiate between them and choose the one that matches our lifestyle? The answer is simple: a Mohs scale rating.
Whether you are new to gemstones and are shopping for something that withstands daily wear and tear, or are looking for just another stone for your jewellery, learning about the Mohs Scale is very important. Read the blog below to learn more about the Mohs scale and make the right choice next time you shop for gemstones.
Mohs Scale 101: Here’s What You Need to Know
The Mohs scale is a simple 1-to-10 scale for measuring how scratch-resistant a mineral is. The rules are simple enough: higher-numbered stones can scratch lower-numbered stones, but lower-numbered stones can’t scratch higher-numbered stones. Talc is super soft at a 1, so you could scratch it with your fingernail, and diamond tops the charts at a perfect 10.
However, here’s a twist. The ratings on the scale are relative rather than absolute. That means the jump in hardness between numbers is not uniform. For instance, a diamond rated 10 is four times harder than a sapphire rated 9.
Another important distinction to bear in mind is the difference between hardness and toughness. Hardness is just a measure of a gem’s ability to resist surface scratching. Toughness, on the other hand, is a measure of how well a stone resists breaking or chipping when a hard blow is applied. A very hard stone can chip if it is hit at just the wrong angle. The Mohs scale is still useful for judging everyday wear and tear, such as scraping against a desk, reaching into pockets, or bumping into car doors. Anything below a 7 is generally too soft for carefree daily wear. Everyday dust contains small particles of quartz, which sits at a 7 on the scale and over time can dull softer stones.
The Right Gemstones for Everyday Wear
Ultimate Champions: 9+
If you want jewelry you can wear and forget about, you need stones that are safely on the higher end of the scale. Diamonds are king in everyday wear. They are the hardest natural substance on earth, a perfect 10. This amazing scratch resistance is exactly why they have been the worldwide favourite for engagement rings and everyday stud earrings for generations. They can take just about anything your routine throws at them and still keep their brilliant sparkle.
Behind them directly are sapphires and rubies, both members of the corundum mineral family and both a fantastic 9. These gems are incredibly durable and come in a stunning spectrum of colours, making them perfect for everyday statement rings and bracelets that will likely bump into things from time to time.
Everyday Contenders: Around 8 and Reliable
Chrysoberyl options like alexandrite are an 8.5 if you’re after beautiful alternatives that are still really durable, while topaz and spinel are a solid 8. These gems are good at resisting micro-scratches caused by dust and everyday contact.
Gems Under 8: Handle with Care
But what about stones that need a little more attention? Emeralds are a variety of beryl, and they score a decent 7.5 to 8, but they have a lot of natural tiny internal fractures. That means they are scratch-resistant but are easily chipped if you hit a hard surface. Gems such as opals, pearls, and tanzanite fall below the ideal threshold for carefree daily wear. While beautiful for special occasions, these softer stones can be scratched easily or become dull if you wear them during household chores or strenuous activities.

FAQs
Do lab-grown diamonds score well on the Mohs Scale?
Yes, lab-grown diamonds, just like natural diamonds, score a full 10 on the Mohs scale. Since these have the same chemical properties as natural diamonds, they are equally durable and excellent for everyday wear.
How should I store my delicate gemstones?
Delicate or softer gemstones, such as opals and pearls, should never be kept with harder gemstones, such as diamonds, as doing so can cause accidental scratches. The best possible way to store your softer gemstones is to keep them in cloth pouches or separate jewellery compartments.
Does a high score on the Mohs scale mean that a gemstone is unbreakable?
No. The Mohs scale only measures a gemstone’s resistance to scratching. This means that even a gemstone like a diamond, which scores a 10 on the Mohs scale, can chip or split under a strong impact.
