Strictly geometrical yet highly ergonomic AAA supports the anatomy of the human hand. The ring’s inner radius is designed to achieve maximum wear comfort. Thus enhanced curvature ensures the ring feels light and loose on the hand. Shapes range from bi-concave to bi-convex, colors from black to white. The natural cloud patterns make every ring unique. Every A is AAA and is part thereof. Palladium and a concrete matrix developed for the purpose complement each other. Both materials dispose of virtually the same coefficient of expansion which in combination with the UHPC’s compressive strength of approx. 200 MPa enhances the product’s longevity.
