Tgis Laramar Stone is imported from the Dominican Republic. The blue looks like the sky and the ocean. The white looks like the sky. Its name when I was there is from the man who discovered the mine, his name was Larry and his daughter Marlene, thus the name arrived!! The stone is very large  approx. 2" long. The open cuff is  for a larger wrist size although it is adjustable when you squeeze it. The beauty is when you look upon it you will truly enjoy its character. Indeed it is a rare treasure one of a kind piece.
