Ruby isn't just the birthstone for july, it's also the perfect colour for the festive period. These gold plated sterling silver studs feature a single 4mm cubic zirconia crystal placed into a rub over setting. This type of setting means the full focus is on the rich ruby stone! The studs measure 5mm high x 5mm wide x 4mm deep and have 11mm pins. They weigh just 1g for the pair so they are also super lightweight! Pair with a set of smaller emerald green studs to create a dazzling christmas look!
