Is there a convenient list/graph which details the elasticity of certain stones... how much they expand and contract with heat/cold?
I was thinking about mounting a Turritella shell on a cab to create an interesting pendant. One of my ideas was to create a cab that had a window through it - in which a shell can be anchored at the top and bottom of the window (so the wearer could view both front and back of the shell).
The Turritella shell has been "chalcedony replaced" ... turned into an agate. So it might have a ratio of expansion and contraction different from the stone (window) of the cab... say... Aventurine or Jade.
I do not want the Turritella shell falling out of the mount on a hot day or shattering on a cold one from compression.
In general... This topic might also apply to intarsia cabs as well???
