These earrings remind me of one of  the 260 black and white striped columns located in the courtyard of the Palis Royal in Paris.  They feature a black and white striped gumball that measures approximately 15 mm in circumference and a frosted and etched  glass Swarovski component with a solitary crystal in the center of the oval.   The earrings are finished with oxidized black lever back ear wires that feature a small round crystal in the front.  The total length of the earrings is about 2 and 1/2 inches long.
