These are a pair of handmade birch wood earrings. They are round earrings and the diameter is about 5 centimeters. The wood has a special pattern that you rarely see with birch wood. The weight is about 2 grams per earring.
The birch branch from which these earrings are made had been in the forest for some time. As a result, the wood was affected by fungi. The nice thing about this is that the fungi have left a beautiful dark drawing in the wood. This made it possible to get a pair of handmade wooden earrings from this beautiful piece of birch.
