Diamonds Eduion - PureGemsJewels
Because our simulant diamonds are almost as hard as a natural diamond, we are able to polish and cut the stones into beautiful gems that are nearly indistinguishable from the real thing. This is why we offer our lifetime warranty on every stone, because we are confident that our stones will not fade, yellow, or lose their brilliance.
Super Hard Ceramics – They don’t get much tougher | …
Boron Carbide, for instance, is currently the hardest material produced in tonnage quantities and is the third hardest material known to man after diamond and cubic boron nitride. Not far behind it in the hardness stakes comes silicon carbide, more commonly known as carborundum, steeped in history since it was first mass-produced in 1893 and probably the most common of all industrial abrasives.
