Another point of interest at this time, is Quartz, so from the book,

QUARTZ,Including varieties
Agate and Chalcedony
Silcone dioxide
Hardness 7
Crystallized quartz is very seldom Fl: however, the agate and chalcedony varities will often fl green or yellowgreen,

back asap,

Re: A girls best friend?

Opps, starting a new page makes comparing the pics a little hard, so I suggest bring up another AGF window, and flick between pics in page 1, and page 2, please note, flicking between the pics gives a real true idea of turning out the lights or blocking natural light, and turning on a ultravoliet light,and see the goodies glow,

I have recoloured the previous pics 1 and 2 to show best i can, what I do see when using my uv light today,

(2)

testing

dredger, that is cool! What are your thoughts on the different colors and how do the colors relate to types of gemstones?

Maybe I missed something? I will re-read the posts.

Very clever Dredger, so you are seeing the same colors that I see. I saved your pics in my photo program so easy to compare. There are many minerals that fluoresce these colors, but I don't understand why there are not larger pieces of the same material

Re: A girls best friend?

Hey Geo.

:confused: I don't know much about types of gemstones, but I think only Diamond opal and Amber are the only one listed in the uv light booklet, I think uv light reacts with other Gemstones and glass or minerals containing uranium but have feeling I know too little more to comment,we know from the hand book.

Quote, From the Versalume by Rayteck, portable ultraviolet lamp, hand book / bible,: smile:

DIAMOND
Native Carbon
Hardness 10
Gem diamonds have been found that fl in a variety of colours including green, orange,red and blue, usually best LW. blue is the most common fl colour. Diamonds react well to the longest ultraviolet rays and even to shorter wavelengths of visible light. the blue-white colour of a fine diamond is often enhanced by daylight fluorescence. Unquote,

Which does not say the quality of the diamond " can " be determined by uv light, ?? and nowhere in the booklet says much about quality of anything,??. Also I heard a voice from somewhere that man made diamonds do " not " glow, no sure about though, cause the only diamonds i would look for would be from a river,

Opals do glow well, and at this time opals are recovered from the opal tailings mounds by or on a conveyor belt below uv lighting, they are finding plenty of good opal thrown away by the old miners, or walking around the mining sites at night, with a uv light in u hand, but u have to watch out for the open shaft in the darkness, :smile:

I think the real benefit here is the situation that I found myself in, many years after I started gold panning I was not aware of diamonds in the area, I did not know what they look like, and I found them when I used uv light, and did not know anything or do anything cause I did not know the value that was and is there ,until I looked on e-bay, :confused:
Back soon bob,:smile:

Yes interesting, but it appears to me that the general size shown in your pic is much smaller then I experience, and I think too small to be payable diamonds, ????. if they are diamonds, ??:confused:

I have no reason to think these are diamonds. Even if they were there would be no value. The blues are a bit larger, but all are very small.

Re: A girls best friend?

Hi,
Diamonds do fluoresce blue. I shall try to explain a bit more.

How to identify a diamond in the field. If you can do buy a hand-held electronic diamond tester.

It is relatively easy a few things to remember.

1) All diamonds have a natural oily layer on them that repel water.

2) A diamond does not get hot

3) It is a crystal and many have triangular shapes on the sides.

4) It can be any color but it will have the same characteristics

5) All diamonds have a very special shine to them in their uncut state one you will never forget once you have seen one.

6) Carry a 10 x loop (Magnifying glass) with you it helps to show the inside of the stone and usually there are maybe one or two spots in them or a small shift in the crystal itself.

7) The usual diamond shapes are: Octahedron, Dodecahedron, Cubes

Whole and Irregular Shapes
8) A diamond does not get wet so blow your hot breath on it and there will be no moisture on it.

9) Place the stone on a newspaper if it is not completely cloudy. Try seeing the print through the stone. If you can read the print or see it clearly, the stone is likely a fake. This test can have mixed results if your stone is very cloudy

10) Scratch the surface of a small compact mirror. A real diamond should have no trouble scratching your mirror. You can also try rubbing the stone with sandpaper. A real diamond should not be scratched


Rough diamonds that are modified forms of the octahedron, dodecahedron and cube and display both rounded faces, points and ribs are referred to as whole diamonds. If the same conditions prevail and the rough is elongated its known as an irregular. These shapes are common to river bed and alluvial placer deposits reflecting the rounding of edges that occur through weathering and transport from their surface origin to the place where their found as a placer deposit.
Hope this helps.
Andy

Re: A girls best friend?

Thanks Geowizard,

A little more diamonds also fluoresce blue, then yellow, orange, green and white. It all depends on the color of the stone. However some diamonds do not fluoresce. So this is not a standard you can hold for all diamonds.
The pure diamond does not fluoresce it is the impurities in the stone that does.
As soon as I figured out how to put pictures on I will show a bit more.
Below is a standard diamond grading scale for those lucky ones that find a big stone!

The Color grading chart
Color Description
D
E Colorless diamond
F
G
H Nearly colorless diamond. Appears colorless when set into a piece of jewelry
I
J
K
L Faintly-tinted diamond. Usually yellow tint.
M
N
O
P Very lightly-tinted yellow diamond. Color is visible to the eye.
Q
R
S Z Light yellow diamonds. Color is very visible to the eye, even when set into jewelry

If I lead anyone to think I have held a raw diamond, I accidentally misled you.


Well, I've held a few. These were found at Crater of Diamonds in Arkansas. Not by me though, darn it! These are real! I like the yellow the best.

Depending on a close inspection those stones are around $1200 not bad for a day out.
I hear several big companies have tried and failed to work that pipe over the years.
I cannot help but cringe...
Put me and my gear on it and someone will retire Dude!
Great picture!

They have several people that have paid a special fee and they have an small area kind of like a claim that only they can work. They dig deeper holes. Some of them are rumored to do well.

Whats funny is seeing this at the entrance to a state park.



Kind of like the picture I have of my truck with a 4" dredge in the back parked in Yellostone Park.
