Gold-tone and "marble" Jewelry Set - necklace, earrings, bracelet

All items have been worn a few times. I don't know the metal content but all pieces are costume/fashion jewelry and are gold-tone with "marble" look accents. Necklace measures 30" with a 2" extender and lobster claw clasp. The pendant measures 3" including the bail. The bracelet is a bangle style with ball/eye closure and measures 2.5" at the widest part when closed. It is bendable. The earrings are for pierced ears and measure 2.75" from top of hook to bottom of dangle.
