The room was dimly lit. Armed guards stood at both entrances and enormous ironclad doors were slid shut to seal the gallery.
Nobody spoke above a whisper as we waited for the first glimpse in half a century of one of the world's most extraordinary gems.
The Wittelsbach-Graff Diamond was last seen in public at the 1958 World Exhibition in Brussels. After that, it disappeared and its whereabouts remained a mystery until Laurence Graff, a billionaire diamond dealer, bought it at auction in 2008, appending his surname.
He and his son Francois were in the gallery of the Smithsonian's National Museum of Natural History in Washington DC as the blue stone, was brought up from a secret vault and finally revealed.
Flawless beauty
"I've been privileged over the years to own some of the world's most important and famous diamonds, but I would say that the Wittelsbach-Graff is the most valuable and the most
beautiful," he said.
Sitting unadorned on a silken white cloth, it glittered grey and blue in the low light. Classed as "internally flawless" it is said to have exceptional colour and becomes intense orange when viewed under ultraviolet light.

The Olympia Diamond Collection consists of five diamonds that have been graded as 'vivid', the highest level of color saturation possible, by the Gemological Institute of America (GIA).
The diamonds range in size from 1.01 carats to 2.34 carats and represent five of the strongest colors that naturally occur in a diamond, namely blue-green, orange-yellow, purplish-pink, blue and orange.
March 26, 2010, jewelry.comThe first stone comes in the guise of a large emerald and diamond brooch once worn by one of the world's most powerful and ruthless female leaders, Catherine II of Russia. The hexagonal-cut stone weighs between 60 and 70 carats and is surrounded by rose and old mine-cut diamonds. The estimated price for this little beauty clocks in at around $1 to $1.5 million.

If you're not worried about little things such as a mortgage, bills, car payments, the price of gas or what your friends would say, Jewelry.com has found a little Bluetooth headset that might just be what you've never wanted.

Diamonds are specifically renowned as a material with superlative physical qualities; they make excellent abrasives because they can be scratched only by other diamonds, Borazon, ultrahard fullerite, or aggregated diamond nanorods, which also means they hold a polish extremely well and retain their lustre. Approximately 130 million carats (26,000 kg) are mined annually, with a total value of nearly USD $9 billion, and about 100,000 kg are synthesized annually.[2]
The name diamond derives from the ancient Greek adamas (αδάμας; “invincible”). They have been treasured as gemstones since their use as religious icons in ancient India and usage in engraving tools also dates to early human history.[3][4] Popularity of diamonds has risen since the 19th century because of increased supply, improved cutting and polishing techniques, growth in the world economy, and innovative and successful advertising campaigns. They are commonly judged by the “four Cs”: carat, clarity, color, and cut.
Roughly 49% of diamonds originate from central and southern Africa, although significant sources of the mineral have been discovered in Canada, India, Russia, Brazil, and Australia. They are mined from kimberlite and lamproite volcanic pipes, which brought to the surface the diamond crystals from deep in the Earth where the high pressure and temperature enables the formation of the crystals. The mining and distribution of natural diamonds are subjects of frequent controversy such as with concerns over the sale of conflict diamonds (aka blood diamonds) by African paramilitary groups.
