We love these star-shaped stud earrings and we think you will too. They're made from sterling silver and feature a 4mm amethyst CZ crystal - the birthstone for the month of February if you're looking for a birthday gift for your loved one. Alternatively you could buy them just because you love the colour - we won't tell! They weigh 1.5 grams and come with butterfly backs. Check out the full range for more colours.
