Finding Diamonds

09/16/2010 4:14 AM

Hi guys haveing been told that raw diamonds flouress when black lite is shone on them i had a thought that if i towed a black lite behind a quad bike and then had a means of looking at the lite through a optical device then a sprectrum interface of some description then to a laptop on my handle bars of the quad i could cover alot of ground looking for diamonds and if i found one i could see the sign on a bargraph or similar scale on the laptop,Now i would presume there are going to be alot of varibles so the question is,is this a viable way to go about this and where would i look for the bits and pieces to do the project .Thank you,Peter Evans.

Try close to volcanos. There you'll have a small chance. But you'll have more luck in the jewelry store.

Why don't you volunteer at your local social service agency.

That won't be a huge waste of time and money like your (searching for the kindest word here) "project".

It might also provide some personal satisfaction, unlike your diamond fiasco.

How do you ripen a raw diamond?

Flourescence + dirt = 0. They'd have to just be laying there, wouldn't they. You should probably direct your efforts more towards RF or sonic considering the density of the "quarry". Good luck! If it works my fee is one great big one.

I don't know if it is true that (raw) diamonds fluoresce when illuminated with 'black light', but IF they do, the emission spectrum will probably vary depending on the impurities in the diamond that give the diamond its color. A LOT of things fluoresce when exposed to black light, so you'd need to know what the possible spectra are when diamonds fluoresce, otherwise you could be continually stopping to check to see if the item is a diamond or a piece of common quartz.

Of course, you'd need either to operate at night to see the diamond fluorescence or have your search contraption completely block out sunlight, since sunlight will wash-out the fluorescence. Even then, the dirt that coats the diamond would likely block the effect so you might miss a huge diamond.

But, it would give you an excuse to go ride your quad bike for a while without your wife complaining you promised to take her shopping for shoes. /"Honey, I'm gonna go try to find you a big diamond."

Might be good to try (if they flouress) at a park where lots of people have gathered over the weekend for some concert or large event and then Sunday night when everyone is gone you can cruise all over the park and look...

Or buy a metal detector and get some exercise while walking through the park on Monday morning when everyone is back at work - that way you can not only find diamonds set in rings you can find other rings and lots of spare change (yes I am speaking from experience).

To find diamonds you have to be in the right place. Volcanic area, kimberlite is the associated mineral. You can ride your bike a long way without any chance of finding a diamond, if you are in the wrong terrain. And of course, it would have to be lying clean on the surface.

Also, not all diamonds are fluorescent. Interesting thing about diamond fluorescence - it actually makes the diamond worth less.

Ok let me explain a little bit about where i,m looking .i live on the west coast of Australia in what is known as the pilbra,reputably the oldest part of the world so old in fact that NASA scientists often come hear to study the hematites at a place called the north pole incidentally customs and the federal police are currently investigating the theft of some of these precious rocks by unscrupulous international thieves apparently from japan, so rumour has it.Any way as you could imagine this area is full of all sorts of minerals ranging from rubies emeralds gold etc etc.you could say it's like an Aladdin's cave.It is also rumoured to have diamonds and because of the area's vastness and inhospitable critters such as the perente dragon ,death adders and various other dangerous animals not to mention the extreme heat and the sometimes impassible terrain i require a system to use in conjunction with a quad bike to scour the creek beds at nite looking for this elusive booty instead of sitting around the camp fire eating greasy sausages drinking Melbourne bitter beer and listening to the wild dogs lurking in the shadows,So i hope this gives you guys a bit of a picture where i go looking for different rocks and minerals i have heard that deberes surveyed a area close to where i thinking of and found red diamonds now wouldn't that be a buzz to find some of those,if they exist.I need some teco help to do this i think

i made a mistake there not hematites they are stromatolites sorry

Oh - is that where you are, well that makes sense to try and rig up a black light to an atv. Possibly the Lake Thetis area, or the Hamelin Pool Marine area near Shark Bay perhaps. I would think the dried creek beds near Lake Thetis would be a good spot to start. Yes, NASA is keenly interested in that area, some of the oldest known fossils are there too. You could secure an inexpensive inverter, connect to your tv battery and have an AC powered black light plugged into the invereter. Mount it a few feet in front of the atv so you can watch the ground in front of you. Good luck, sounds like fun.

I have been giving this quite alot of thought and maybe there is another way of finding then .As diamonds i think are crystals shoulden't they activate within a certain frequency like radio crystals and if so could you recieve or identify them somehow.Perhaps if this could be done it wouldn't matter if the diamonds had dirt on them or were a little bit under the surface.

If there was a way of detecting diamonds remotely, such as by using radio waves or similar, then it would not be necessary to crush all the rocks at diamond mines like Argyle up into small pieces to release the diamonds. You could sort out the rocks at a much larger size.

I spent some time at a brain storming session once, addressing just this issue. There were quite a few people from different fields in the group, including an Emeritus Professor of Physics. The conclusion was that it was not possible to reliably detect diamonds inside rocks. So the process remains, in essence- crush, screen, gravity separate, sort by x-ray fluorescence.

So I think we can forget about mounting a radio frequency detector on the quad bike.

hi thanks for that i arn't really looking for diamonds in there carrier rock rather trying to find them in the creek beds where they have wound up over the time we enjoy the journies we take to these remote places and have come across a few interesting specimans including emeralds some of which are quite facitable and deep and clear in colour along with amathest ,jade,devils dice,etc thank you for your reply.Bye the way what we have done is hook a frequency generater up to an amplifier and run 20m x 20m copper wire in a square to find gold with a detector it works quite well.
