Seawater is dynamic in composition, and changes with the natural flows around the globe.

Your home-brewed salt water might have salt from mines below Lake Erie, or Himalayan pink salt, or sea salt from a specific location, or from some other source and composition.

They will all be different in chemical analysis. Some will have bromides. Some will have iodides. Some will have mercury. Some will have whale urine. Who knows?

Lab grown diamonds are cheap knockoffs of natural diamonds.

France was successful in making "roquefort" and "champagne" proprietary trade names, ending the ability of other nations to market knockoffs using those names.

I hope the powers that be make the term "diamond" proprietary and force the labbies to use a different term other than "diamond", like "damnonds" or "deamonds" or "shillite".

Again, your lack of precision is astonishing for the "smartest" ass on the board.
