Robert Lee Morris Gold Plated Pushed Pebble Station Necklace. A common theme with the RLM forms are soft pebble and stones that have an indented concave well in it . Like the sandstone boulders out in New Mexico where water and wind have carved smooth indentations, like soft craters. This is a station chain made of a variety of these golden pebbles, soft to the touch, like worry stones in ones pocket. Gold plated brass, so it has a nice weight, and is 30″ long, able to be worn doubled.
