Red wine bracelet clasp

O.K., so it is not exactly a glass of wine, but it is close in color. I fell in love with these deep red vintage pieces when I saw them. It is red without being bright-like a good claret. The piece begins with a gold base upon which the red glass was laid down. The red is swirled so that there is a lot of interesting texture on top the glass. The pattern is almost like a vine wandering across the top. The vintage centerpiece is set in a hand-made sterling silver box clasp. The centerpiece is 14 mm by 18 mm. The clasp is 32 mm from ring to ring.
