For the longest time, I have had this orthoceras pendant, and I never knew what to do with it, until now!  I paired it with white howlite since they both have the same unique gray tones.  Orthoceras is an extinct nautiloid, which have been carefully preserved in stone for millions of years.  

Materials are: white howlite faceted beads, an antique silver plated metal claw pendant, white leather cord, wood and horn beads, an orthoceras stone pendant, a silver plated brass oval cross pendant, with a silver plated brass necklace clasp and extender chain.  Length of necklace is 18.5", white howlite beads are 1/4" wide, and orthoceras pendant is 2 5/8" long and 3/4" at its widest point.  It is slightly on the heavier side, so it is not for those who are unaccustomed to wearing slightly heavier pieces.
