On the other hand, aragonite has an orthorhombic crystal structure that makes it harder than calcite. This gives it greater durability and resistance to scratching and abrasion. In addition, by comparing the two crystals side by side, you will see that aragonite tends to be darker in color while calcite is usually lighter.
These distinct physical characteristics between calcite and aragonite make them ideal for various uses: from jewelry making to rock tumbling applications, each crystal cousin offers unique advantages depending on your needs. Understanding their differences in hardness as well as their respective crystalline structures can help you decide which one fits best for your project or application. Knowing this information will empower you to confidently select the appropriate material for whatever purpose you have in mind.
Chemical Composition
Both calcite and aragonite have the same chemical composition of calcium carbonate, but their distinct crystal structures can make them behave differently in various situations. This is because they are formed from different molecular arrangements, which result in varying crystal formations. For instance, calcite has a trigonal crystalline structure that allows for more flexibility than aragonite’s orthorhombic structure. As a result, these two minerals react differently to certain environmental conditions such as temperature and pressure. In addition to this, the variations in their molecular arrangements also contribute to their distinct physical properties like hardness and solubility.
These two mineral cousins may possess similar chemical compositions, but they are far from identical when it comes to their molecular structures and crystal formations. This helps explain why they react differently under certain circumstances and have diverse physical characteristics. Moving forward, let’s take a look at where these minerals occur naturally in the world around us.
