Sometimes the best designs are the simplest designs. These rings focus on the beauty and brilliance of the gemstones and the sheen of the 14K gold that encompasses them. The birthstone of June, Alexandrite is an amazing and mysterious stone. A created alexandrite ring is a unique and entertaining attention getter. The birthstone of December, the tranquil azure color of a blue topaz ring can evoke thoughts of warm Caribbean seas on a cold winter day.
