What is the Mohs hardness scale and why is it important?

When it comes to selecting an engagement ring, the beauty and brilliance of the gemstone are top priorities, but there's another critical factor to consider: durability. The Mohs hardness scale plays a significant role in determining how well your gemstone will stand up to daily wear. At S.E. Needham Jewelers in Utah, we understand the importance of choosing a stone that will not only dazzle but also last for generations.

What Is the Mohs Hardness Scale?

The Mohs hardness scale, developed by Friedrich Mohs in 1812, is a ranking system that measures a mineral’s ability to resist scratching. The scale ranges from 1 (softest) to 10 (hardest), with talc at the lowest end and diamond at the highest. Each mineral can scratch those below it on the scale, but not those above it.

Why Is the Mohs Scale Important for Engagement Rings?

Your engagement ring will likely be worn daily, which means it needs to stand up to potential knocks, bumps, and scratches. This is where the Mohs hardness scale comes into play. Knowing the hardness of your chosen gemstone ensures it can withstand everyday activities, such as washing dishes, typing, and gardening, without losing its shine or getting damaged.

For example:

  • Diamonds rank at a 10, making them the hardest known natural material. This is why diamonds are the most popular choice for engagement rings—they are virtually scratch-proof.
  • Sapphires and rubies (both forms of corundum) rank at 9 on the scale, making them excellent alternatives for engagement rings due to their high resistance to scratching.
  • Moissanite, another popular engagement ring stone, comes in at a 9.25, offering great durability and sparkle at a more affordable price than diamonds.

Gemstones on the Lower End of the Mohs Scale

While some gemstones may be stunning, their lower Mohs hardness may make them less suitable for engagement rings that will be worn daily. For example:

  • Opals (5.5-6.5) and emeralds (7.5-8) are more prone to scratching or cracking. While they can be used in engagement rings, extra care must be taken to avoid damage.

If you have your heart set on a softer gemstone, consider a setting that offers more protection, like a bezel setting, or wear the ring occasionally rather than daily.

How the Mohs Scale Impacts Your Choice

When choosing a gemstone for your engagement ring, it’s essential to consider how active your lifestyle is. Do you work with your hands frequently? Do you want a ring that can endure daily wear and tear without frequent maintenance? If so, choosing a stone with a high Mohs hardness rating—like a diamond, moissanite, or sapphire—will ensure your ring maintains its beauty over time.
