The Russian Institute of Geology and Mineralogy announced
an allegedly previously undisclosed 60-mile-wide field of "trillions of carats" of impact diamonds caused by a metor strike into graphite rock in Siberia. The media is reporting that this has been known about since the 70s but undisclosed
, but this is misleading. As detailed by Vishnevsky [academic summary PDF]
, for example, the presence of large amounts of impact diamonds within the impactites was very well known; it is perhaps better to say that the market-distorting sheer yield of the field (around an order of magnitude of increase over known reserves) had not previously been discussed. The diamonds produced by such high temperatures and pressures are around twice as tough as normal diamonds, and the extreme hardness and compartively cheap availibility is likely to hugely widen the usage of industrial diamonds
even setting aside the gemstone issues. This does however put the 2011 sale of the Oppenheimer family 40 per cent stake in De Beers
in an interesting light, especially as the field at once offers the prospect of huge diamond stones whilst devaluing De Beers' existing stockpile hugely.

Current TV previously & previously
, the media company founded by Al Gore after the 2000 election, has picked up the kinds of in depth long form journalism being rapidly dropped by major networks, but has been tantalizingly unavailable for those without cable; until now. They have been putting their Vanguard episodes up on their website and on YouTube. [more inside]

The White Diamond
was one of three documentaries released in theaters this year (in the U.S.) by legendary filmmaker Werner Herzog
(the others being the more widely seen Grizzly Man
, about a man who studied bears in Alaska, and Wheel of Time
, about the practices and rituals of devout Buddhists). In The White Diamond
, Herzog introduces us to Dr. Graham Dorrington
, a professor of aeronautics who is obsessed with weightless, floating flight, and who is testing the design of a new airship in a large hangar outside of London. Herzog and Dorrington travel to the rainforest of Guyana, where Dorrington hopes to fly the small dirigible over the jungle’s canopy and study the innumerable plants and animals living there with the hopes of finding new species and potentially discovering plants with pharmaceutical and healing benefits – a practice he calls “canopy prospecting”.

, a symbol of love for a large part of this century. Yet there is an underlying monopoly who have socially engineered the whole entire idea that a "Diamond is Forever". Does your notion of a diamond change knowing that a consortium is ensuring that their Monopoly is Forever?

Most Valuable Object in the World
The Supreme Purple Star - as it is being called - is a deep purple diamond, turning to crimson when rotated in the light. Diamonds come in a rainbow
of colors and are called "fancies
" in the trade. Some are beautiful
, others less so
. This one is the only one of it's kind, and has been pronounced "priceless". The speculation, of course, is that the owner is looking to sell it.
