Thomas Sabo Sterling Silver Collection Royalty Stud Earrings These high-quality ear studs are made of 925 Sterling silver with an 18ct yellow gold platting and designed with attention to detail. A dark blue glass-ceramic stone and a synthetic spinel in light blue sparkle within their centre. Their colours reflect the nocturne sky, and the sparkling effect resembles the stars at night. The faceted stones are roundly cut and set into the earrings by hand. They are fashionable pieces of jewellery for every day and can be combined within the ear candy style with other ear jewellery.
