14-Karat gold and freshwater pearls. Hoops are 3/4″ across. Artist’s card included. About the Artist: Tom Kruskal’s designs are rooted in his interest in mathematics and music – which lend a sense of proportion, balance, movement and grace to his work. The designs are all original and grow out of hours of his personal experimentation. Tom Kruskal’s jewelry is completely hand fabricated in New England using a cold forging technique followed by heat treating; this process allows the jewelry to be remarkably graceful and sculptured – yet exceptionally strong.
