What Is the Range of the Mohs Hardness Scale?

Understanding the Mohs hardness scale is crucial for anyone interested in gemstones, whether you're a collector, a jeweler, or simply someone shopping for jewelry. At Robinson's Jewelers, we believe in educating our customers, and today, we're exploring the Mohs hardness scale, which measures the resistance of minerals to being scratched. This scale is instrumental in helping determine the durability and wearability of gemstones in jewelry.

The Mohs Hardness Scale Explained

The Mohs hardness scale ranges from 1 to 10, with 1 being the softest and 10 the hardest. Talc, a very soft mineral, has a Mohs hardness of 1, while diamond, the hardest known natural material, is rated at 10. This scale helps jewelers and consumers understand how well a gemstone can withstand scratches and daily wear.

For instance, diamonds (10), rubies (9), and sapphires (9) are on the higher end of the scale, making them excellent choices for engagement rings and other jewelry intended for everyday wear. On the other hand, materials like talc (1) and gypsum (2) are considered too soft for most types of jewelry.

Choosing the Right Gemstone

When selecting a gemstone for your jewelry, consider its Mohs hardness rating. Stones with a Mohs hardness of 7 or higher, such as topaz, quartz, and amethyst, are more resistant to scratches and suitable for rings and bracelets. Those with lower hardness are better suited for earrings or pendants, which are less exposed to abrasive forces.

At Robinson's Jewelers, we offer a wide selection of gemstone jewelry, catering to various tastes and preferences. Understanding the Mohs hardness scale can enhance your appreciation for gemstones and help you make informed decisions about your jewelry purchases.
