Triton is the son of Poseidon and the messenger of the sea. Like his father he carried a trident. However, Triton's special attribute was a twisted conch shell, on which he blew like a trumpet to calm or raise the waves.
The contour of this conch shell, also known as triton shell, is used for the design.
When you are concidering a steel ring, I recommend to order a 1/2 size bigger than your normal ringsize.
Steel is less dimensionally accurate than other Shapeways materials, which means the ring shrinks in size (about 0,6mm in diameter) during production.
