“Diamonds, pearls, sapphires, emeralds —visions of beautiful women loaded with jewels. This talk isn’t about that aspect of jewels. No, sir. Today I’m going to talk about the way jewels are pulling their weight in the war. Do you realise that seventy-five per cent of the diamonds produced annually arc employed in industry and the jobs that they carry out are of vita] importance? Not all industrial jewels arc produced naturally, in fact the majority are synthetic and man-made. Their value lies in their extreme hardness which makes them suitable for forming cutting tools for metals and for bearings in precision instruments.”—S. A. Gregory, in “Science Notebook,” a B. overseas series.
