[QUOTE="Heatho, post: 327024, member: 487"] I wonder how many poor diggers destroyed their beautiful diamonds...... They will generally shatter as they are so brittle, I guess depending on how hard they are struck. Actually diamonds from the Copeton/Inverell area are the hardest that have been discovered anywhere. To facet them you need to make paste from the same diamonds from the same area, well so I have heard. I havent belted a sapphire with a hammer yet, though I did belt a piece of spinel one time with a hammer on concrete, first whack didn't do much, second whack it sounded a bit different and third whack sent razor sharp small shards flying everywhere, the whole stone basically disintegrated.
