Amateur rock hound needs ID help (diamonds?)

[rockfairy]

Hi everyone

I just happily stumbled upon this website while looking for some info about rough diamonds.

I have found a bunch of what I suspect are rough diamonds of various sizes and colours. I suspect I have found alluvial, red and black diamonds while fossicking around Stannifer/tingha/Inverell areas earlier in the year.

I'm looking for some advice on correctly identifying my little treasures. So far I've attempted the at home methods of testing and also bought a diamond tester ( although I think I may need to invest in a better quality one)

I welcome any advice or tips as I just want to learn more.

If confirmed diamonds I would also like to sell some after potentially having them cut.

Cheers
Em the rock fairy

Hi Em. Some pictures shouldn’t be too hard to post. Would help others to help you.

Hi Geoff, thanks for that, I'll take some tonight or tomorrow and post them

Please try and take pics using backlighting, so that colour and transparency can be seen. On top of a torch can work well (with a sheet of white paper between the stones and the torch if necessary to reduce glare).

I think you might be restricted on what you can post before you have 10 posts. You might not be able to post photos at this point?

I don't think that restriction still exists, Phil.

while your at it what are peoples thoughts on these? Found deep in a crevice on a fast flowing creek

Where? Could be Quartz, Zircon, Sapphire, Topaz. Too hard to tell from pics.

Put them on a dark background and take a photo close up. Would help more.

Go upstream and see if a car has been dumped, looks like windscreen glass.

The creeks is through a huge private property No roads up past creek higher than crevice they came out of and the stones cut glass.

Some diamonds will also glow blue under UV light even though all may look the similar to the naked eye. It is highly unpredictable and from appearance one cannot tell which diamonds will fluoresce and which not. On average about a quarter (25%) of diamonds will show some degree of fluorescence from weak to strong.
So how can this possibly help?
Most other fluorescing gems or minerals will consistently fluoresce ie a panful of stones would all fluoresce together or at least a much higher percentage.
So what would be expected if a UV light was shone over the pan of diamonds that looked visually similar.
Really a mixture of some that fluoresced (about 25%) and the rest that didn’t.
A result like that would certainly suggest you take them for more expert physical evaluation.
