It's not just the Mohs number that matters; crystal structure and chemical composition also play a vital role in determining hardness. Crystals with a stronger bonding force between their atoms tend to be harder than those with a weaker bonding force. For example, the cubic structure of diamond ensures a rigid and compact molecular arrangement, giving it exceptional hardness. In contrast, the hexagonal structure of calcite, a relatively soft mineral, results in a weaker bonding force, making it more susceptible to scratching.

Hardness is not merely a theoretical concept; it has practical applications in the field of gemology. By assessing the hardness of a gemstone, jewelers can determine its suitability for various purposes. Harder gemstones, like diamonds, are more resistant to wear and tear, making them ideal for everyday jewelry. Softer gemstones, such as amber, require more care to prevent damage.
