I used Inkscape and GIMP to process the original image source (symbol of Freyja). Then, I modelled the amulet in Blender.

In Norse mythology, Freya is a goddess associated with love, sex, beauty, fertility, gold, seiðr, war, and death. Freyja is the owner of the necklace Brísingamen, rides a chariot pulled by two cats, keeps the boar Hildisvíni by her side, possesses a cloak of falcon feathers, and, by her husband Óðr, is the mother of two daughters, Hnoss and Gersemi. Along with her brother Freyr, her father Njörðr, and her mother, she is a member of the Vanir.
