Color Rings by Israeli designer Itay Ohaly are pieces of jewellery carved from layers of coloured paint applied to a wooden table.
Ohaly spends months applying a layer of acrylic paint per day, then slices through the thick surface to create the raw material for the rings.
The rings often include slices of timber from the table beneath the paintwork.
Here's some info from Ohaly:
The rings were carved out of an old painting table, taken from a children's furnitures carpentry.
It takes 4 month of daily painting to reach this thickness, creating a new material to work with.
The layers are acrylic paint, while the wood is a part of the original painting table.
