Vintage Hobe Sterling Silver and Lucite Necklace

This vintage HOBE pendant necklace features a marbled Lucite oval slab with silvertone accents. The pendant measures 1 inch across by 3 inches high. It hangs from a Mexican 925 sterling silver neckband. The pendant is marked HOBE on the back. Would guess this to be from the 1970s or 1980s. It's in excellent condition.
