These minimalist round gold knuckle rings in 2mm, 4mm, and 6mm are awesome! They are simple and elegant in design, and the gold sheen is very beautiful, and they look very layered when paired together. The material is sturdy, comfortable to wear, and perfect for stacking, which can show personality without losing elegance. I really like this fashionable and versatile ring, which is definitely a good choice to enhance the overall look! Highly recommended!
