These 9ct yellow gold stud earrings feature genuine green peridot gemstones. Naturally they can be worn any time of the year, but peridot is also the August birthstone if you are looking for a gift for someone with a Leo zodiac sign. With a face size of 7.5mm x 5mm and measuring 11mm from front to back, these earrings are stamped with a 375 metal mark and look great in our craft packaging.
