Yellow or rose gold fill- you get to choose which warmth of gold you want for the cup studs you'll be wearing most days of the week. Super versatile, easy to wear and stylish to boot. These studs are small but mighty- coming in at approximately 3/8" diameter, they look great on everyone and are attention-getters. Their concave surface captures light beautifully whether it's the bright yellow gold fill or the warmer pink hue of the rose gold fill. Each cup is hand textured and shaped to give a little eccentricity to the surface and edge.
