[QUOTE="SWright, post: 44657, member: 1541"] Hi all Diamonds are generally quite easy to tell from other stones. First they are heavy and will get trapped in any sluice, second they cannot be wet - this is a strange thing but trust me. It means that diamonds will always, unless disturbed, be found on the bottom of a stream like gold - or on clay bottoms. They will generally retain their octahedral (Diamond shaped) shape even after travelling long distances. Shattered ones only occur in or near primary deposits and will more often than not be a part octahedral shape. If you think you are in a diamond producing area, like Beechworth, first jig your material, then pan it. If there are any white, or suspicious stones that are not obviously other stones such as sapphires, zircons and such, then you can do a simple SG test or have them X rayed. araluen [/QUOTE]
