A stunning obsidian and sterling bracelet by Felipe Martinez who opened his workshop "Piedra Y Plata" in 1950. The surface of the S shaped stones is smooth and highly polished and impeccably fused into the silver. The design beautifully combines movement, line and color. This bracelet,c.1955, is featured in the Morrill book MEXICAN SILVER on page 189 with a green variegated stone rather than obsidian. Measuring 6 3/4" end to end and 1" wide, this piece is in fine original condition and signed for Felipe Martinez, Piedra Y Plata as shown. Exquisite in every way.
