Consider the following simple
example. Dust rates 7 on the Mohs hardness scale. Yes, dust! The stuff that floats in
the air! It has the potential to scratch a variety of surfaces. In the event that you
are a daily glasses wearer like me, you've undoubtedly run into this problem: after a
few cleanings, your glasses will appear slightly hazy and you'll have to blame dust and
other particles for it.
The same stands true for gemstones, as well.
Attempting to clean a gemstone with no proper care will almost likely result in it being
scratched by dust, among other things. As a result, be careful while selecting a
gemstone engagement ring or any other ring design. Your best option is to choose a
gemstone that is at least 7.5/10 in grade on the Mohs hardness scale, and ideally
higher. The closer to 10/10 (diamonds) your gem is, the more durable it will be on your
finger.
