Diamond?
« on: December 16, 2014, 08:11:41 PM »
Hello,

I was doing some test panning in a new location and I think I found a diamond but not 100% sure, found it in Central Alberta.

In that photo it can't be disinguished from any other kind of glassy looking substance. Try looking at it under magnification, and look for triangular shapes in it, either as indentations or raised forms. That would confirm it as a diamond. It almost looks like it has a triangular form toward the bottom close to your finger, but the photo is too blurry to be sure. Diamonds often have a blue glow under UV light too.

if coming out of gravels it could be well tumbled and there will be no triangular surface marks. also there are 3 different ultraviolet lights. short, medium and longwave. find out what length diamonds react to and use that wavelength. a good hardness test kit will also give you a clue.

Keep in mind that fluorescence, or lack of,  isn't definitive in diamonds. Most diamonds don't fluoresce at all. Of the ones that do, the majority fluoresce under longwave light.

Unfortunately, a more common mineral that looks like diamond is quartz.  Quartz is hexagonal  (6 sides). When looking down on the crystal from the top, with a jewelers optic, with the point of the crystal aimed at your eye, a diamond will have (only) 4 sides.  Other thing to do is take it to your local jeweler and have them test it with a thermal absorption tester.  Most other tests are indicators.  Good luck with it.  Some diamonds have been found in Alberta

Crystallography: Isometric. Crystals sometimes sharp octahedral, rhombic dodecahedral, cubes, twinning, plates, and combinations with other forms. Crystals modified often rounded and distinguished by the presents of triangular shaped pits on the faces of the octahedral shaped crystals.

I read somewhere that diamonds repel water, is this true and if so can it be used as an indicator?  At one point I found some small rough diamond looking pieces and dropping it into a pan with water residue the water would "run away" from the piece.  Other similar looking pieces from a different place had no effect on the water.

Are there other materials that have the same effect?
