The heart-shaped design makes the earrings look romantic and lovely, suitable for matching with various styles of clothing and occasions. Zirconia is an artificial crystal and is often used as a substitute for jewelry because it looks like a real diamond but is more affordable. This type of earrings is usually one of the favorite accessories for women and can be worn for daily wear or special occasions.
