Thermal conductivity of gem stones (2 replies)

I recently aquired several raw or uncut stones possibly moisanite or saphire have heated a few to glowing  point and dropped in cold water.

    So my question is what other stones aside from the afore menchioned are capable of this type of thermal conductivity?

forgot to say the stones passed the test multiple times with no visible effects.

It will depend on the the individual structure of each mineral sample.  If there are any significant inclusion or fractures planes (which may not be visible) then the stone can fracture quite significantly.  If there no major inclusions or fracture planes then the stone may not fracture.  To determine if it will or will not fracture/shatter you either have to try it or do a detailed microscope and xray examination.  This type of test is expensive.  So just keep trying.  Of course if it shatters it is now worthless, so if you have a lot of money to waste keep at it.
