A perfect choice for yourself, or as a gift, our Lab Ruby stud earrings feature sturdy cast basket settings and beautiful sparkling gems. Ruby signifies passion and unbridled, unrestrained love, making a pair of ruby earrings a perfect Valentine's day gift. A pair of peridot earrings sparkle by day, and remain brilliant at night.
