Solid copper washers have been used to make these earrings. They have been textured, using a ridged hammer, which makes them catch the light as they move.  The earwires are sterling silver (Eco Silver) which contrasts beautifully with the copper. They have been photographed on a piece of Malvern stone in the rockery in my front garden, which shows off the copper colour, with smooth pebbles above, reflecting the circular shape.
