Hexagon, round, oval and a larger triangle in cobalt blue, not sure it is a salt but certainly useable as one, or for spices, etc. The cobalt blue measures just under 3" at the widest point with and opening of about 2 1/8", 1 1/2" in height, 1 1/4" deep, base about 1 1/4" wide, a solid piece weighing 3.9 oz. The pink oval salt, lower left in pictures, has a nice rose pattern viewed inside or on the bottom, the bottom being etched into the glass. The light lavender salt, lower right in the pictures is hexagon shape, about 1 3/4" at the wide point and shows some UV in black light. The oval gold colored salt by Royal Rudolstadt Prussia, has some paint chips as visible in the pictures. The spoon is plastic.
