In gemology, gemstones are typically categorized into two groups: precious stones and semi-precious stones. The four main precious stones are diamonds, rubies, sapphires, and emeralds. All other gemstones—such as quartz, agate, and carnelian—are considered semi-precious. Despite the term "semi-precious," these stones can vary greatly in beauty, rarity, and value. Each type has unique properties, identification methods, and cultural significance.
One of the most popular semi-precious stones is tourmaline, known for its wide range of colors. Crystal, or quartz, is another widely used stone, often associated with clarity and energy. Lapis lazuli, with its deep blue color, has been valued for centuries, while topaz comes in various hues and is often used in fine jewelry.
Other common semi-precious stones include garnet, peridot, tiger's eye, labradorite, and moonstone. Obsidian, a volcanic glass, is also popular, especially in decorative and spiritual applications. Malachite, with its striking green patterns, and turquoise, known for its vibrant blue-green shade, are also widely appreciated.
In addition to mineral-based stones, organic gemstones such as amber, pearls, and coral are included in the semi-precious category. These materials have their own unique characteristics and are often used in both traditional and modern jewelry designs.
With the growing popularity of crystal jewelry, many semi-precious stones have gained more attention. They are now commonly featured in fashion accessories, home decor, and even wellness practices. As a result, the term "crystal" is sometimes used more broadly to refer to all these beautiful and diverse stones.
Whether you're collecting, wearing, or simply admiring them, semi-precious stones offer a fascinating world of color, texture, and meaning. Their affordability and variety make them accessible to a wide range of people, ensuring their continued appeal in the world of gemstones.
