Hey bookcliff...Marc no longer owns this site...I don’t know how far I can go with the new owners...I don’t want to draw in very many of the skeptics so I am just trying to be as cool as possible...Art
More larger crystalline Lamproite, my hand at bottom front for size comparison.
If you try to dowse for very large raw diamond crystals, some locations if the host rock is a Lamproite pipe, these might be what your rods pick up on instead. Of course, there should be at least a few raw diamonds near them also.
Once frozen during the cold of winter, they turn soft to weather away. Your location probably freezes deep. So maybe warmer climates such as Arkansas or Brazil would be the place to find crystalline specimens.
The way the geologist explained it to me, once brought up to the surface and the Lamproite goes through the winter exposed to freezing temperatures, weathering begins. I was told also, when the diamond mines were operating there, Lamproite diamond ore was put on piles, so it would weather away. The piles were stirred, you don't crush the ore. The ore becomes soft, the material is then run over a greased table for diamonds to stick, other stuff washes off. Weathered ore can be soft enough, you may crumble it with your fingers. Once weathered, it won't work as a specimen, about all it is good for is to crumble and fill up your gold pans. Here the black gold pans were only used to haul ore back to the car. All pieces got crumbled some to make sure they are weathered enough and not specimen grade. Also the broken up material takes up less space in the car.
I think it's harder to pick up a single loose raw diamond, the first signals would come from the best placer locations.
At times my rods spun around and pointed off behind me, looking back there would be someone walking. So many people have diamond jewelry on them, the cut diamonds have a greater value than many of the raw diamonds in the field.
Hello bookcliff,
Dowsing revealed an attraction to alluvial diamonds in the areas of the white circles. Bold circles are pinpoints and thin circles a wide attraction area. Alluvial gold in the areas of the green circles. Garnets in the areas of the red circles.
Some locations I received a mixed attraction. All these areas were weak attractions but repeatable over time.
Thanks for posting your picture,
Jon
In field dowsing signals are strong from distance on large targets. To give an example, as just mentioned about at Crater of Diamonds State park. Since the more recent geological survey, they discovered 2 additional diamond pipes were formed during after eruptions. The southern smaller pipe comes into the mine field right exactly the spot I map dowsed, giving me all the diamond ore (had the same spot marked in my map dowsing before the trip). This signal over powered everything else in the area for nearly 300 feet. There was a guy running a barrel sifter, another guy digging for him just downhill from me. It was noisy hearing them work. Later people told me he has found thousands of diamonds working the spot.
The flag Am-C1a is where the vein enters the mine field (probably runs SE). The barrel sifter guy works the area just S of map bottom.
The other 2 diamond pipes are still in the hill area. It's more like a vein runs into the mine field at only 1 spot, the barrel sifter guy was working S edge area.
