A pair of channel set, clip earrings in white paste and mother of pearl.  'Channel Set' is where stones are set into a channel - between 2 pieces of metal - rather than by claws or stuck in.  Gem stones jewellery is often set in this way.  It was popular in costume jewellery in the Art Deco period - and continued into the 1950/60s.  They were probably made in Germany.  This pair have channel set white paste stones with a piece of mother of pearl in between.  Sets of this jewellery were made and these earrings would be very useful for someone seeking to match up a necklace or bracelet.  They are in good condition and measures approx 1/2 x 3/4 inches.
