With absolutely no football bias whatsoever, our diamond experts were asked to pick their 10 favourite Super Bowl rings .    After a much heated debate, here is the that list.

Top 10 Super Bowl RIngs

1. 2001 – Super Bowl XXXVI – New England Patriots

A diamond-filled ring with the Patriots logo front and centre on top of the Vince Lombardi trophy.   This  eye-catching piece of jewelry made everyone’s list and was easily our favourite.

2.  2006 – Super Bowl XLI – Indianapolis Colts

enhanced-buzz-wide-5161-1422485601-10

 

We enjoyed the simplicity of the Indianapolis  Colts’ ring.   The logo surrounded by diamonds like stars with the words Super Bowl XLI Champions on the face.

3.  1998 – Super Bowl XXXIII – Denver Broncos

enhanced-buzz-wide-19901-1422484278-8

 

The Broncos logo with the simple words “World Champions”.   We liked the added touch of the name Broncos quarterback John Elway on the side of the ring.   This game would end up being his last as he retired before the next season.

4.  1986 – Super Bowl XXI – New York Giants

enhanced-buzz-wide-24108-1422482255-52

 

A diamond-filled Lombardi Trophy with the words “Giants World Champions” and “1986” surrounding it.   It is one of the least busy looking of the rings, we liked how dramatic it made the trophy in the centre of the ring look.

5.  2009 – Super Bowl XLIV – New Orleans Saints

enhanced-buzz-wide-18601-1422485774-29

 

As bright and vibrant as the city itself, the New Orleans Saints’ championship ring is filled with diamonds and stones so it is eye-catching from every angle.

6.  1983 – Super Bowl XVIII – Los Angeles Raiders

enhanced-buzz-wide-23966-1422481974-12

 

A vast rectangular spectacle, the ring has three stones on the face to represent the three Super Bowl championships that had been won by the franchise.

7.  1971 – Super Bowl VI – Dallas Cowboys

enhanced-buzz-wide-6789-1422478343-11

 

The first of three Dallas Cowboys rings on our list, this first one is also the oldest ring on our list.   It had the perfect combination of old school style and new school shine.

8.  1995 – Super Bowl XXX – Dallas Cowboys

enhanced-buzz-wide-31782-1422483934-18

 

In some ways, this Dallas Cowboys’ ring harkens back to the team’s 1971 ring.   The distinctive logo on the face is similar, the wording is even more simple with just the franchise name on it.

9.1992 – Super Bowl XXVII – Dallas Cowboys

enhanced-buzz-wide-19771-1422483552-16

The only ring on our list with the wording on the side of the face and an “all seeing eye” type of look to the logo on the front.

10.  1982 – Super Bowl XVII – Washington Redskins

Of the rings on the list, this has the smallest writing on the face but it doesn’t take away from the blinding, football-shaped centre.

A Rare Blue Diamond Find

blue diamond - Cullinan

An extremely rare, acorn-sized, blue diamond has been recovered in the Cullinan mine of South Africa, announced this week by Petra Diamonds.

According to the company’s press release, the 29.6 carat diamond is “a vivid blue with extraordinary saturation, tone and clarity”.   Still in its rough form, experts believe that the stone could sell in the $15-$20 million range.   The company will announce what it plans to do with the diamond within the next week or so.

Since opening in 1903, the Cullinan mine has been the main source of blue diamonds in the world.   However, the output of the rare blue stones represent less than 0.1% of the diamonds found in the mine.   The blue shading in a diamond is due to the presence of the chemical element boron when the stone was formed.

The location first became famous in 1905 with the discovery of the Cullinan Diamond.   At 3,106 carats, it still is the largest rough diamond ever found.   Once it was cut, the stone was formed into two diamonds that are now part of Britain’s Crown Jewels located in the Tower of London.

The larger of the two diamonds is the 530-carat First Star of Africa.   It is still the largest flawless cut diamond in the world and is mounted at the top of the Sovereign’s Sceptre.   The second diamond, called the Second Star of Africa, is a 317-carat polished stone which forms the centrepiece of the Imperial State Crown.

World renowned diamond company De Beers originally owned Cullinan mine, they sold it to Petra Diamonds in 2008.   Petra made the news in April 2013 when they recovered a blue diamond that weighed in at 25.5 carats.   It was sold for $16.9 million less than a month later.

Bracing For The “Lesotho Pink Storm”

Lesotho_Pink_Storm

A storm has entered the diamond world as a Type IIa 36.06 carat pink stone called the “Lesotho Pink Storm” is set to be tendered by Fusion/Hennig Tenders later this month.

The stone is considered to have “exquisite gemological characteristics” and was recovered by Storm Mountain Diamonds in the Kao Mine in the Kingdom of Lesotho, the African country surrounded by South Africa.

Lesotho made a big splash in the diamond world in 1967 when the Lesotho Brown Diamond was discovered in the Letsang Diamond Mine.   The stone weighed in at 601 carats  in its rough form and a total of 18  diamonds were produced from it.   The most famous of the diamonds was the Lesotho III, given to Jackie Kennedy by her husband Aristotle Onassis.

The Lesotho Pink Storm is currently available to be viewed in New York City before making its way to Antwerp, Belgium for further viewing until finally being tendered.

Fusion Tenders CEO Adam Schulman said that “We are thrilled to have the privilege of tendering this truly rare and exceptional stone. It is not often that a rare diamond of such significant size, color and quality are found together in the one stone. This is a unique opportunity for someone to own a very special diamond.”

Considering the size and rarity of the diamond, experts here at Ouroboro Diamonds are sure it will easily sell for over a million dollars, with a possible price tag closer to ten million dollars depending on the amount of interest at the tender.

Diamonds In The Deep

Journey_to_the_Center_of_the_Earth1959

Is Russia looking at taking the first steps toward diamond mining under the earth’s crust?

According to scientists at The Russian Academy of Sciences, they have determined that diamonds may have harvested in the areas between tectonic plates in the earth’s lithosphere.

By definition, the earth’s tectonic plates are the sublayers of the top crust of the planet.   They move around and interact with each other causing what scientists believe is the current alignment of the land masses of the planet as well as the volcanoes and earthquakes we continue to experience.

The group of Russian scientists, led by Yuri Pulyanov, have taken minerals common to the areas between the tectonic plates and simulated the amount of heat and pressure that would be found that many kilometres beneath our planet’s surface.    These minerals would crystallize and become diamonds.

As we have discussed in previous posts, the demand for diamonds could outweigh the supply of the stones within the next decade.   Could this be the first step to tipping the scales back?   Or is this merely just a fanciful film idea like Journey To The Center Of The Earth or The Core?

Keep in mind, what lies beneath the earth’s surface isn’t a new area of discussion for Russia.   They began an ambitious drilling project in the 1960s to reach below the planet’s  crust.  The project became the Kola Superdeep Borehole in the Pechengsky District of the Soviet Union.   The goal had nothing to do with searching for diamonds, it was merely an attempt to see how for down they could drill.    The hole, which ended up reaching seven miles deep, was  abandoned in 2005 due to lack of funding.   Perhaps this famous hole could become the starting point of the first subterranean diamond exploration.

India’s Impending Diamond Boom

British-Australian mining company Rio Tinto is planning India’s first diamond discovery in over 40 years.

According to Business Standard, Rio Tinto expects to produce three million carats of diamonds  annually starting in 2019 from its Bunder deposit in Madhya Pradesh’s Bundelkhand region, 500 km south-east of Delhi.

However, this plan is yet to be made official.   Rio Tinto still needs to get the appropriate environmental and forest clearances before they can start actually mining.   That part of India is known to be near areas roamed by monkeys and tigers.   Environmentalists point to a tiger habitat approximately 100 km from the mining area as a particular cause for concern.

If all goes to plan, mining would begin operation in 2017 with yields forecasted two years into the project.   The company expects the mine to be operational for 25 years with almost 30 million carats of rough diamonds anticipated.   The production cost for the company is expected to run at half a billion dollars.

It’s been a long road for Rio Tinto who first starting working on the project in 2002 as part of a regional exploration reconnaissance program.  However, based on these projections, the Bundelkhand region would become one of the top-10 diamond-producing regions in the world.

Australian-based Lucapa Diamond Company has announced the finding of a 32.2 carat, type IIa rough diamond from their Lulo concession in Angola.

According to Lucapa’s official announcement, the stone has an irregular, dodecahedral and is of exceptional colour (rated D-the highest for white diamonds) and clarity.   It has yet to be determined if the diamond clarity will be rated flawless.

Trading of shares in the company were halted in the Australian Securities Exchange on Friday January 3rd after the announcement was first made.   Share trading re-opened for the company on Monday January 6.

Lucapa has spent four years of exploration in the the Cuango River Basin of Angola’s Lunda Norte Province.   Last week’s stone is the largest recovered by Lucapa through the new Dense Media Separation plant which they commissioned in November 2013.   It is also the fourth largest diamond ever recovered at that location to date.
