Just to let you know I will be using it in my presentation. Gemologist, Appraisal Lab, Consumer Fraud Expert , GemPrint Center, Diamond Switch Case Consultant. Anything use where cutting or polishing is important, you'll usually find diamonds being used. Also note than many industrial users are buying synthetic diamond too. Automobile glass winshields are polished with diamond compound.
Many diamonds also conduct electricity well also.
They are widely used in satellites, communication devices, etc. Small diamoonds also are mixed into nail polish to add some sparkle as well as hardness. Thank you Rock Doctor for your reply. I'm working on the presentation at the moment. I will be mentioning this forum within the presentation.
