Hope you never have a fire where you keep your diamonds as they
burn real good. All they are good for is industrial use. Diamond is
only carbon that made under pressure and De Beers
Roy- Yes they are only carbon. However a house fire would not harm
them. It takes a s**t ton of direct heat to smoke a diamond. Even
then they can be re faceted to their original shine. If they "burned"
they wouldn’t survive the heat and pressure it takes to make them.
Trust me on this. I’ve done restoration to house fired damaged
jewelry and silverware.
