The tiny green bowl pictured here was made by wrapping clay around an actual sea urchin — capturing the five pointed symmetry of this echinoderm.

Only sea urchins from Newfoundland are used — all are tiny and all are green.

The $22 bowl is made with the largest sea urchin, it usually measures about 6-7 centimetres (2.5 to 3 inches) rim to rim.
