Jasper stone is composed of silica which gives this stone an opaque appearance. Does not matter which type of jasper you consider, each and every jasper specimen contains tiny quartz crystals that have gained a distinct color and pattern because of mineral impurities present in trace amounts, such as the presence of iron in the case with red jasper. On the Mohs Scale of Mineral Hardness, jasper ranks 7, which makes it a dependable stone in the field of jewelry making. Because almost all jaspers have vibrant colors and patterns, lapidaries and jewelers fashion them into polished cabochons, thereby highlighting the intense colors and patterns of the stone. Although jasper is considered the zodiac stone for Virgo, Aries, and Scorpio, different types of jasper stones are considered apt for different zodiac signs. For instance, the red jasper is considered beneficial for Aries and Scorpio because it supplies them with extra endurance. Similarly, the bloodstone jasper is the traditional birthstone for the month of March.
