A perfect choice for yourself, or as a gift, our White Topaz stud earrings feature sturdy cast basket settings and beautiful sparkling gems. White topaz is a popular substitute for the birthstone of April, which is diamond. A pair of white topaz earrings is an affordable alternative to expensive diamond studs. A pair of peridot earrings sparkle by day, and remain brilliant at night. The Romans called peridot the “evening emerald†whose vibrant green color remained visible by lamplight.
