This necklace has 3 strands of 1/2" square pressed glass beads. After some research I believe these are Antica Murrina Glass Jewelry.
Antica Murrina Veneziana started in the 1960′s when the Voltolina brothers began creating various works of art from glass, using the old tradition of working the Murano glass. The biggest step for them was taken in 1988 when they've added to their business one of Venice's oldest and most important tradition, the unique method of creating glass arts, the Murrina.The Murrina technique of glass making was discovered in ancient Roman times but it became really popular in the 18th century, when the technique was so evolved that it allowed designs to be very elaborate and complicated. Long canes of glass are cut into tiny pieces and put together to form a design. The shape is then heated in the oven until it melts into one piece, to create the famous Murrina.
If you do any research on Antica Murrina Beads, necklaces just like this one are being shown. The beads on this necklace are plainly pressed glass and not uniform in shape with lines showing where the glass went through the side of the mold. I believe this is one of the earlier necklaces of their company. The beads are strung and knotted on a black silk looking string and wrapped at the end to make a hook and loop closure. The longest strand is 21" long with 2 shorter strand the smallest being 18". The beads are an amber and a darker amber or brown with the smaller end bead being made to look like a flower.
