This incredible amethyst cake may look like it'll crack your teeth, but in reality it is 100% edible.
Created by award-winning cake designer Rachael Teufel, the design is made from granulated sugar, rock candy and multicoloured chocolate.
Teufel, who is the owner of Intricate Icings Cake Design, made the cake for an industry event but the pictures have quickly gone viral.
The masterpiece took around 20 hours to create in total, including 16 hours to craft it and a few hours planning.
"I was given several pieces of inspiration to draw ideas from, including actual geodes, a beautiful illustration and a variety of table decor items like plates, chargers and geometric floral arrangements," Teufel told The Huffington Post. "I knew I wanted to create a show-stopping cake and use the geode as the focal point, creating an awe-inspiring visual experience for the guests."
