Hey there! As a supplier of round shape moissanite, I often get asked about the hardness of these beautiful gemstones on the Mohs scale. So, let's dive right in and explore what makes round shape moissanite so tough.
First off, what's the Mohs scale? It's a scale that measures the hardness of minerals. Developed by Friedrich Mohs in 1812, it ranks minerals from 1 (softest) to 10 (hardest). Talc, for example, is at the bottom with a rating of 1, while diamond sits at the top with a 10.
Now, where does round shape moissanite fit on this scale? Well, moissanite typically has a hardness rating of 9.25 on the Mohs scale. That's pretty darn hard! To put it into perspective, only diamond is harder than moissanite. This high hardness means that round shape moissanite is extremely resistant to scratching.
If you're thinking about getting a piece of jewelry with round shape moissanite, this is great news. You won't have to worry too much about everyday wear and tear scratching up your gemstone. Whether it's brushing against your clothes, hitting against a table, or just the general hustle and bustle of daily life, round shape moissanite can take it.
This hardness also makes round shape moissanite a great choice for engagement rings. Engagement rings are worn all the time, and they're bound to encounter some knocks and bumps. With a hardness of 9.25 on the Mohs scale, your round shape moissanite engagement ring will stay looking shiny and new for years to come.
Let's compare moissanite to some other popular gemstones. Take sapphires, for instance. Sapphires have a hardness of 9 on the Mohs scale. While that's also very hard, moissanite is just a little bit tougher. Emeralds, on the other hand, have a hardness of around 7.5 - 8 on the Mohs scale. That means they're more prone to scratching compared to round shape moissanite.


One of the reasons round shape moissanite is so hard is its chemical composition. Moissanite is made of silicon carbide. The strong bonds between the silicon and carbon atoms give moissanite its high hardness. These bonds are difficult to break, which is why moissanite can withstand a lot of pressure and abrasion.
Now, I know you might be thinking, "If it's so hard, is it brittle?" Well, moissanite is not very brittle. It has good toughness, which means it can withstand impacts without cracking or breaking easily. Of course, like any gemstone, it's not indestructible. If you were to hit it with a hammer or subject it to extreme force, it could break. But under normal circumstances, round shape moissanite is quite durable.

In conclusion, the hardness of round shape moissanite on the Mohs scale is 9.25, which makes it an excellent choice for jewelry. It's scratch - resistant, durable, and has a great sparkle.
