The North Star Signet Ring represents the brightest star in Ursa Minor. A guiding star; a star that is used as a reference point in navigation. Let this ring represent your personal North Star, your guiding light: the values, priorities, or people that keep you pointed towards true north. Garnet is the birthstone of January and has been used in jewelry for thousands of years. Dating back to the pharaohs of Egypt, garnet is believed to protect wearers from evil and disaster.
