Gregory Pyra - Poland (b. 1951) A contemporary and elegant design, Polish born Gregory Pyra's jewelry pieces are original hand sculpted works of art. The jewelry is made with a European technique using a torch that melts sterling silver and 18k gold into unique, never repeated shapes. This remarkably comfortable ‘C’ ring features iolite, and amethyst gem stones paired with faceted and polished blue glass. A one of a kind work of jewelry art. Artist hallmarked. size 6
