Orangeite as far as I know, does not contain diamond unless
the diamond falls into it. A text book definition for
kimberlite is: "A rock type that rarely contains diamonds"

Only a small percentage carry some micro-diamond and from
those fields that have micro-stones, only a few contain
economic amounts of diamond.

Some kimberlite have perfect geo-chemistry and no diamond, and
other are off and produce diamond. The Lesotho diamond mine
of DeBeer's produced only large stones and had almost zero
micro count.

As far as shapes I'm sure Orangeite is not unique and probably
comes in all the usual shapes, pipes, dykes, sills... and I
know someone will say kimberlite does not come in sill shapes
after I post, but they do, I've seen them, never seen a cone
sheet before. I've met Dr. Bob and he is not knowledgeable
about diamonds, nice guy though.
