Artsy Lucite Jewelry Set

Eclectic artist-made lucite necklace and earrings set. Necklace features a sterling silver rope chain with fluorescent lucite bars in orange and yellow; the centerpiece is a cantilevering silver bar in a rigid silver frame. Lightweight (hollow?) silver earrings resembling an industrial rod with fluorescent gold lucite at base. These items were originally purchased from an art gallery in Traverse City, MI, but artist is currently unknown. There is a small silver tag bearing the makers mark "mnp" near the lobster clasp. In addition metal stamps on the necklace claps include what appears to be a "925" designating it as sterling silver and the word "Italy." Gently pre-loved.
