Diamonds Discovered in US by Gold Prospector

Posted by Dan Hausel on December 29, 2014 at 7:15 PM Comments comments (0)

Well it happened. One prospector contacted me who recently read my book on finding gemstones. He reported that a university in North Carolina confirmed he had found several diamonds including one, flawless, 5-carat diamond in a placer at one of the many sites mentioned in my book released in late 2014.

This followed discoveries of sapphires at another location by a different prospector and also discoveries of lamprophyres (one of a few rock types known to contain diamonds). We expect that following winter, several more discoveries will be made based on this unique book.

New Gemstone Book Tells the Reader where to find gemstones

Its been in the works since 2011, and it is finally published. My new book tells about my experiences as a gem, gold and diamond hunter and also tells you where you can find your own gemstone deposits. For instance, there appears to be a major opal and agate deposit near Douglas, Wyoming, but no one is looking. How about the creeks around Cheyenne, Wyoming - some may contain diamonds and gold - but no one is looking.  These are just two examples of what is in store for you.

Pink Diamond Sells for $83 Million!

Posted by Dan Hausel on October 14, 2014 at 2:00 PM Comments comments (0)

The $83 Million Pink Diamond Default

Diamond cutter Isaac Wolf outbid three rivals for the 59.6-carat “Pink Star” diamond, offering about $83.2 million, a world record for any gem sold at auction. He renamed it the “Pink Dream.” Unlike many who would make a purchase like this, he revealed his identity and explained why he bought the gem. In fact, he did everything in a proper manner except for one thing: He never paid for it.



The diamond is graded as Type IIa, which is rare for any pink diamond, much less one of this size and color. It is twice the size of any vivid pink diamond ever brought to auction and the largest known diamond rated vivid pink. David Bennett, chairman of Sotheby’s Jewellery Division in Europe and the Middle East and chairman of Sotheby’s Switzerland, said the diamond is one of the most important gems he has seen in his 35-year career.


“It is difficult to exaggerate the rarity of vivid pink diamonds weighing only five carats,” he said prior to the auction. “So this 59.60 carat stone is simply off any scale, and passes, I believe, into the ranks of the earth’s greatest natural treasures.”


The oval-cut gem was the highlight of the November auction in Geneva. It was estimated to fetch more than $60 million. The bidding opened at $48 million.


The diamond was originally mined in South Africa in 1999 as a 132.5-carat rough by De Beers. It was cut by the Steinmetz Diamond Company over a two-year period and was formerly known as the “Steinmetz Pink.” In 2003, it was shown publicly in Monaco and was displayed at the Smithsonian Institute as part of its “Splendor of Diamonds” exhibit. The Pink Star was sold privately in 2007, according to Wikipedia.


It certainly livened up a routine post-earnings report. As one investor representative said, “Just to get to ask questions about a pink diamond on a conference call is really pretty cool.”

Pink Diamond Sells for Record Price

A fancy 8.41 carat, pear-shaped, flawless pink diamond sold for a record $17.8 million in Hong Kong this week, over $3m more than what Sotheby's was expecting to fetch, setting a world auction record on a per-carat basis for this kind of gems.


The auction house did not reveal the buyer's identity, but said than 200 people attended the bidding at the Hong Kong Convention and Exhibition Center in Wan Chai.


This pink diamond sold for a historic record of $18 million

The most expensive pink diamond ever sold.


Internally flawless clarity is extremely rare in pink diamonds, and the auction house said this, in combination with its "fancy vivid" colour grading, made the stone "amongst the rarest and most desirable of coloured diamonds ever seen at auction".


Pink diamonds are rare, and only one in 10,000 of mined diamonds qualifies as the sought-after “fancy” or “intense” grade, according to GIA, the jewels institute.


Coloured diamonds shortage has helped push diamond prices up, to the point that these rocks are now the world’s most expensive stones. A 14.82-carat orange diamond sold for $36 million at Christie’s International in Geneva in November, setting a record $2.4 million a carat. The same month, Sotheby’s sold the Pink Dream, a 59.6-carat pink stone, for $83 million.

Pink Star

Just a month after setting a world record for the most valuable White diamond sold at auction, a 118.28-carat D-flawless that sold for $30.6-M on 7 October in Hong Kong, Sotheby’s Geneva expects to set another record on 13 November, when the Pink Star crosses its block." target="_blank">Pink Star, a 59.6-carat internally flawless vivid-Pink diamond is expected to fetch more than $60-M. It is the largest stone of this color and clarity ever graded by the Gemological Institute of America (GIA), according to Tom Moses, the institute’s senior vice president. “The occurrence of pink diamonds in nature is extremely rare in any size,” he says. “It’s our experience that large polished Pink diamonds over 10 carats very rarely occur with an intense color.”

The Pink Star is part of a rare subgroup of diamonds known as Type IIa that are considered the most chemically pure diamond crystal, with extraordinary optical transparency.

The 132.5-carat rough diamond was mined by De Beers in Africa in Y 1999 and cut and polished by Steinmetz Diamonds over a 2-yr period. Christened the Steinmetz Pink when it was unveiled for an exhibition in Y 2003, the stone was 1st sold in Y 2007 and was later renamed the Pink Star.

It was displayed at the Smithsonian Institution in Washington, DC, in the 2003 Splendor of Diamonds exhibition, along with 7 of the world’s rarest diamonds, including the De Beers Millennium Star, the Allnatt diamond, and the Moussaieff Red.

The Pink Star is more than twice the size of the Graff Pink, the 24.78-carat fancy intense-Pink diamond that established a world auction record for a diamond and any gemstone or jewel at $46.2-M from Sotheby’s Geneva in Y 2010. The current record price per carat for a Pink diamond at US $2,155,332, was set by a 5-carat fancy vivid-Pink diamond. (

Large Pink Diamond Recovered at Argyle Mine

Mining group Rio Tinto has unearthed an extremely rare pink diamond.


It discovered Australia's biggest rough pink diamond, named the Jubilee Pink, at its Argyle mine.


The diamond is similar to the Williamson Pink, given to Queen Elizabeth II as a wedding gift in the 1950s.


It is thought to be worth millions of dollars but no-one will know its price until it goes on sale later this year, with selected potential purchasers being invited to bid for the huge gem.


The BBC's Duncan Kennedy in Sydney has more details.

Record Price for Sapphire

Posted by Dan Hausel on March 21, 2014 at 3:20 PM Comments comments (0)

When most of us think of corundum, we visualize the intense pigeon’s blood purplish-red color of Burmese ruby, the satiated blue of Kashmir sapphire or the subtlety of pink and orange Padparadscha sapphire. Sapphire and ruby are two of the better known gemstones in the world and two of the more valuable gems.


Rare pink Padparadscha sapphires of Sri Lanka are extraordinary, but, it is the blue sapphire that brings the highest prices for sapphire. One 62-carat royal-blue rectangular cut sapphire sold for $2.8 million. In 2007, another Kashmir blue sapphire of 22.66 carats sold for US$3,064,000 or $135,216 per carat and in 2012, another Kashmir blue 8.91 carat cushin cut sapphire sold at auction for $1.37 million, or $154,000 per carat.

Over this period, he found more gold and gemstone deposits than most people in history and mapped more than 1,000 square kilometers of complex geological terrain that included South Pass, Rattlesnake Hills, Copper Mountain, Seminoe Mountains, State Line district, Iron Mountain district and Leucite Hills.

While at the Survey, he was a prominent public speaker, not only in Wyoming, but also all around North America. He presented more than 400 public and professional lectures and was presented more than 50 awards for public speaking. He was a Distinguished Lecturer for the University of Wyoming Department of Geology and Geophysics and was inducted into the National Rock Hound and Lapidary Hall-of-Fame for public speaking and education of rock hounds.

He published more books, papers, articles, maps and abstracts than any other geologist in the history of the Wyoming Geological Survey: more than 1,000 publications that included contributions to nearly 100 books.

He was induced into more than a dozen halls-of-fame around the world as a martial arts instructor. He taught karate, kobudo, iaido, jujutsu and self-defense at the University of Wyoming and was recently awarded two of the top honors in martial arts.

In 2013, He was notified by Marquis Who’s Who in the World that this is the 10th anniversary since his initial induction into the prestigious compendium.

Geologist Recognized by Who's Who

Posted by Dan Hausel on May 24, 2013 at 1:25 PM Comments comments (8)

Arizona geologist and martial arts instructor, Dan Hausel, was notified by Fred Marks, Editor-in-Chief of Marquis Who’s Who of his inclusion in the forthcoming 68th Edition of Who’s Who in America 2014. Hausel was first selected as a Who’s Who honoree more than 25 years ago and has since appeared in many biographical compendiums celebrating his accomplishments and achievements as a martial arts instructor, scientist, writer, artist, public speaker, astronomer and musician.

The laureate martial arts instructor has also been inducted into 16 Halls of Fame since 1998. These include the World Martial Arts Black Belt Hall-of-Fame, Action Martial Arts Magazine’s Hall of Honors, World Head of Society Hall of Fame, American Karate Association Hall of Fame, Latin America Martial Arts Society Worldwide Hall of Fame, North American Black Belt Hall of Fame, World Karate Union Hall of Fame, National Rock Hound & Lapidary Hall of Fame, Millennium Hall of Fame and others.

He began training in martial arts in the early 1960s. In 1999, he reached the highest level in martial arts when awarded certification as sokeshodai (grandmaster) and kudan (9th degree black belt) at the Juko Kai International hombu (world administrative headquarters). At that time, he was teaching karate, kobudo, jujutsu, samurai arts and self-defense the University of Wyoming while working as a research geologist.

Over three decades he discovered many mineral deposits (precious and base metals, colored gemstones and diamonds) and was awarded economic geology’s highest honor with six other geologists in 2009 – the Prospectors and Developers Association of Canada’s (PDAC) Thayer Lindsley Award for a major international mineral discovery. He authored nearly 1,000 books, papers, maps and abstracts on prospecting, geology and martial arts, mapped more than 1,000 square kilometers of complex geology and traveled around North America presenting more than 400 lectures on geology as a distinguished lecturer. But because of his research contract, he was unable to financially benefit from any of his mineral discoveries or books including one of the largest gold deposits ever to be found in North America (Donlin Creek, Alaska), a previously unrecognized gold district (Rattlesnake Hills district, Wyoming) and significant gemstone deposits. He found dozens of diamond deposits..

In 2004, he received an unprecedented promotion to judan (10th degree black belt) making him one of a very few martial artists in the world to achieve that rank. In 2012, he received a one of a kind award: he was promoted to junidan (12th dan) and is only one of a handful of martial artists in history to be awarded that rank.

Grandmaster Hausel in currently head instructor of the Arizona School of Traditional Karate located on Baseline at the border of Mesa and Gilbert, and the world head of Seiyo No Shorin-Ryu Karate Kobudo Kai. He is a former instructor of martial arts at Arizona State University, the University of New Mexico, the University of Utah and the University of Wyoming and has taught martial arts to many teachers, professors, librarians, scientists, PhDs, engineers and social scientists.

Geologists find MONSTER Gold Deposit

Posted by Dan Hausel on February 26, 2013 at 3:40 PM Comments comments (0)

W. Dan Hausel recounted discovery of the Donlin Creek gold deposit in Alaska as a member of a 7-geologist team who were later awarded the Thayer Lindsely Award for an International Mineral Discovery by the Prospector’s and Developer’s Association in Canada in 2009. In 1988, he and six other geologists discovered a Monster Gold Deposit in the Kuskokwim Mountains of Southwestern Alaska described by Northern Miner News as the largest undeveloped gold deposit in the world! Hausel, who was on leave from the Wyoming Geological Survey at the time, was consulting for WestGold, a subsidiary of Anglo-American and DeBeers.

The Northern Miner (v.98, no.52, 2013) reported Donlin Creek to have more than 43 million ounces of contained gold! As a comparison, the Homestake gold mine which operated for 123 years from 1878 to 2001, produced 39.8 million ounces of gold and had one of the longest surviving stocks in history on the NYSE. Donlin Creek has stepped up as the new measuring stick for all gold miners in the world. The mine is currently in the final stages of permitting, envisioned to be the largest gold mine in the world.

Hausel is also a Hall of Fame martial artist and found himself at the top of the martial arts world in 2012.  In December 2012 he was promoted to the highest ranked Shorin-Ryu martial artist. Shorin-Ryu is the traditional Okinawa form of karate developed many centuries ago. In 2004, Hausel was promoted to Judan (10th degree black belt) in Shorin-Ryu karate, a rank only achieved by a very small, select group of martial artists from Okinawa. Rarely has a non-Asian reached this level in karate. In 2012 he received an unprecedented promotion to Junidan (12th degree black belt) that has only been awarded to a handful of martial artists in history.

He also recently published another book with his son Eric entitled "GOLD". Dan is an author of nearly 1,000 books, professional papers, maps, popular articles and abstracts.
