Circular curved silver stems tipped at both ends with peacock cultured freshwater button pearls. The unique lustre of pearls depends upon the reflection, refraction, and diffraction of light from the translucent layers. The thinner and more numerous the layers in the pearl give a finer luster. The iridescence that pearls display is caused by the overlapping of successive layers, which breaks up light falling on the surface. These cufflinks are a limited edition of 100 pairs and are made to order with delivery in 28 days.
