The light foil overlays allow the base colour to be clearly seen and the foil is mainly on the raised part of the scales giving the leather a 3D look.
If there is only one colour listed, eg Gold, it means that we have overlaid a heavy foil in gold on a base colour.
The heavy overlay lets a very small amount of the base colour show through, the scales are not as visable and there is more sheen.
Because the leather is a natural product and is not uniform, every single piece of jewellery we make is unique. If you are buying a pair of earrings we try our very best to have both earrings look the same as possible buy cutting them out of leather next to each other.
