Liyolabs from Etsy has created these awesome retro video game rings.
Each design is created from a Mario level which is then printed onto plastic rings. The rings are edged in gold paint and sealed with acrylic for water resistance. Designs include Koopas in Sun and Desert, bullet bill, goomba, and para beetle, and Legend of Zelda. I think they look pretty fantastic to be honest and cute and they are available to buy for $7. Check out her Etsy for more wonderful designs.
