Variations on a spiculum

This photo presents 3 examples of pendants that are based on a spiculum shape. For some time I am experimenting with this form. If you are not sure what a spiculum is than go ahead a read the following explanations.




The free dictionary defines speculum as follows: spiculum - small pointed structure serving as a skeletal element in various marine and freshwater invertebrates e.g. sponges and corals.

Metal smith Andy Cooperman explains
 A spiculum is a hollow cylinder-- a tube-- that is
    tapered, usually to a point, on either end.  Sort of a marquis or
    bean pod shape.  It is most often formed from sheet, using cross peen
    hammers and a grooved work surface to roll up or coax the metal into
    form.
