Silver and Shell Turtle Bracelet Closeup 2

A set of pieces I just made; a necklace, bracelet, and hair dangle.  Featured are silver-tone turtle beads in four styles, a silver and shell turtle center-piece, and gemstone beads (amethyst clearly; I am uncertain what the others are, as they come from the collection my mother left me when she passed), though from their sheen they may be opal or rainbow quartz of some sort).
