"Hello Adventure Guide - yes, based on the level of erosion of the diamond pipes in the Colorado-Wyoming region, at least 2000 feet of the upper level of the diamond pipe columns were eroded. These are usually the richest parts of diamond pipes so it suggests that streams downslope from the State Line district must have millions of diamonds. How far downstream? In Africa, research suggests that gem-quality diamonds most likely were carried downstream from South Africa to the Ocean over a distance of 1000 miles. Most so no evidence of wear and tear.

The grease - we used a mixture of 10 parts vaseline to 1 part pariffin to extract diamonds. I suspect axle grease might also work.

"Hi Aaron,
Actually, all we used was a shaking table and coated it with grease. Then we would run our concentrates across the table wth water. Diamonds are nonwettable and grease attractive. So if the diamond surface comes in contact with grease, it sticks and does not move. However, many companies make the mistake of assuming all of their diamonds are clean - many are coating with a thin layer of carbonate and those in the ocean are often coated with salt and these will not actually come in contact with the grease. So these have to be treated first to remove the thin salt layers.

We use to use so much Vaseline that the town Pharmicist use to accuse us of being affiliated with some of the Sororities on campus."

"Dan,

Is it possible to explain what grease traps are and how o use them? This is very interesting.

Thanks,

Aaron"

"Yeah Tom,
They would actually insult us. Thought we were a bunch of perverts or something (LOL)
