Thomas Sabo Hallmarked 925 Sterling Silver Glam & Soul white imitation pearl ear studs. The core of the imitation pearl, crafted by hand, is made from glass and is coated in more than 10 layers of finely-ground mother-of-pearl dust. The result of this time-intensive manufacturing process is pearly jewels with iridescent colours, whose mother-of-pearl shimmer creates a wonderful highlight. Size: 0.7 cm
