British police have released new images showing the extraordinary lengths the Hatton Garden burglars went to in their lucrative heist over the Easter weekend.

The team of robbers raided a safety deposit business in the vault of a London building, making off with a reported £60 million ($A116 million) worth of precious stones and jewellery.

Police believe they entered the premises through a side door on the night before Good Friday.

The building houses several businesses who share an entrance. Hatton Garden Safe Deposit Ltd was in the basement.

The robbers disabled the communal lift on the second floor then used the lift shaft to climb down into the basement from the ground floor. They forced open shutter doors into the basement where Hatton Garden Safety Deposit is located, then made their way to the vault

A total of 72 safety deposit boxes were opened, out of 999 boxes in the vault. Of these, seven were vacant, and 11 were due to be drilled out for non-payment of fees, police said.

They then used wheelie bins to move the jewels to their white getaway van.

The suspects dressed as construction workers and gas workers, and timed the raid over the Easter long weekend, entering on Thursday night and leaving on Easter Sunday.

It later emerged that an alarm at the premises set off on Good Friday was ignored by police.

Drilling was heard by neighbours but didn’t lead to any investigation.

Police have so far made no arrests.

Brazil Minerals reports large rough diamond. Image from Brazil Minerals.image www.worldwidediamonds.info

Brazil Minerals (OTCBB: BMIX) mined a 4.01 carats diamond, it’s largest to date.

The company said the gem has good appearance with the ability to yield high colour and clarity grades. The company plans to cut and polish the diamond before selling it.

Brazil Minerals is a U.S. publicly-traded company with current revenues from sales of rough and polished diamonds, gold, and sand.

Full news release is below.

Brazil Minerals, Inc. Reports Largest Rough Diamond & Expected Further Cash Flows From Sand Products

BELO HORIZONTE, BRAZIL–(Marketwired – Apr 6, 2015) – Brazil Minerals, Inc. (OTCBB: BMIX) (the “Company” or “BMIX”) announced today that it had mined its largest rough diamond to date at 4.01 carats. This gem has very good appearance and no visible points or inclusions, and thus appears to be able to yield high color and clarity grades. The Company plans to have this rough diamond cut and polished before selling it.

Separately, BMIX announced that conversations are in advanced stages with potential partners regarding aggregate products derived from its high-quality, abundant sand. Aggregate sand products include materials used in construction, such as mortar. Sand is a consistent source of revenues for the Company and able to generate positive cash flows, primarily due to a combination of much lower operating costs and relatively strong demand.

In particular, these sand-based products are much less dependent on the use of diesel, which is the single largest cost in the Company’s mining and processing of rough diamonds and gold. Over time, BMIX plans to substantially diminish diesel use in the plant processing for diamonds and gold by implementing several approaches.

Lucapa Diamond unearths 63.05-carat rock from Angola mine

Australia-based Lucapa Diamond (ASX:LOM) has unearthed a 63.05-caratwhite diamond from its Lulo mine, in Angola.

The stone is the largest diamond recovered since Lucapa and its partners began commercial alluvial diamond mining operations at Lulo in January 2015.

the finding highlights the potential for widespread recovery of large gems from the mine, which could prove to be more valuable than Angola’s biggest diamond producer

According to the miner, the finding highlights the potential for widespread recovery of large gems from the mine, which could prove to be more valuable than Angola’s biggest diamond producer, Catoca, which is also the world’s fourth-largest kimberlite mine.

Lulo, about 700 kilometers (435 miles) east of Angola’s capital Luanda, is a joint venture between the company and the Angolan government. The mine hosts type-2a diamonds, which the company qualifies as “the world’s rarest and most valuable gems”. These kinds of precious rock account for less than 1% of global supply and, according to Lucapa, the world’s most famous large, white, flawless diamonds belong to this category.

Angola is the world’s No.4 diamond producer by value and No.6 by volume. Its industry, which began a century ago under Portuguese colonial rule, is successfully emerging from a long period of difficulty as a result of a civil war that ended in 2002.

The government has recently reduced taxes and cut state ownership requirements as it seeks to rekindle the industry after the global financial crisis forced mines to close.

Scientists reveal diamond bearing rocks more common than originally thought

ROUGH&CUT DIAMOND

A team of Australian scientists have unveiled a ground-breaking study that identifies, for the first time, the exact source of diamond-bearing rocks known as orangeites.

The paper reveals that orangeites —until now believed to be common only to South Africa— may be present in much higher abundance worldwide

Published Monday in the April edition of Nature Communications, the paper reveals that orangeites —until now believed to be common only to South Africa— may be present in much higher abundance worldwide, especially in Australia.

Rough on the outside, these rocks contain not only treasured diamonds but also tiny fragments of mantle and crustal rocks. By using highly sophisticated geochemical and isotopic analytical techniques, the scientists were able to link those fragments to the source of the orangeites, deep in the interior of the planet.

“We found strong evidence that orangeites are sourced from MARID (Mica-Amphibole-Rutile-Ilmenite-Diopside) mantle, which up until recently had only been recognised in South Africa,” leading author, Professor Fiorentini — from The University of Western Australia — said in a statement.  “However, ongoing studies suggest that MARID mantle may occur in other continents, including here in Australia.”

The group also found evidence that suggests orangeites were formed from lava produced by massive volcanic eruptions several tens of millions of years ago. Until now, the common belief was that diamonds were formed about 990 million years ago.

‘Perfect’ 100-carat diamond goes under Sotheby’s hammer Cecilia Jamasmie | April 20, 2015

An internally “flawless” 100-carat emerald-cut diamond that will go under Sotheby’s hammer in New York on Tuesday is expected to fetch up to $25 million.

The gem, discovered a decade ago at one of De Beers mines in South Africa, is one of just five diamonds over 100 carats and of comparable quality to have been offered at auction, according to Sotheby’s.

“Simply put, it has everything you could ever want from a diamond: the classic shape begs to be worn, while the quality puts it in an asset class of its own,” said Lisa Hubbard, Chairman of North and South America for Sotheby’s International Jewellery Division, in the press release.

The current owner of the diamond spent more than a year studying, cutting and polishing the rough diamond before delivering the stone to the auction house.

Sotheby’s sold the first 100-carat perfect diamond at an auction in 1990. The price per carat for these diamonds has increased from $125,000 to $260,000 from the first auction until the most recent, in 2013, the auction house said.

The stone’s details include “100.2-carat, D colour, Internally Flawless, Type IIa stone”, which, for the uninitiated, means it has the clearest colour, without any blemishes on being magnified and is free from imperfections.

Sotheby’s estimates that the auction, which features more than 350 other pieces, is estimated to achieve more than $50 million in sales.

Canada’s Lucara Diamond (TSX: LUC) has added to the excitement of huge gems being found this month by announcing it has unearthed a 341.9 carat gem quality diamond from its Karowe mine in Botswana.

The “exceptional colour and clarity” stone, said the Vancouver-based firm, was recovered while processing fragmental kimberlite from the central and south lobe interface of the mine, located in the central district of the southern African country.

According to Lucara, this Type IIa diamond will be sold along with two other greater than 100 carat diamonds, also recovered at Karowe.

The miner also said that timing of the sale of these diamonds is still to be determined.

Last year, the company sold a 203-carat diamond for $8.2 million for, three weeks after Gem Diamonds sold a 198-carat stone from its Lesotho mine for $10.6 million. A bit earlier, a 123-carat gem from South Africa got Petra Diamonds $27.6 million.

In addition to the Karowe mine, the Africa-focused diamond miner holds 75% of the Mothae project in Lesotho.

De Beers making it harder for diamond dealers to join supply chain

Cecilia Jamasmie | March 30, 2015

De Beers making it harder for diamond dealers to join supply chain

De Beers is fine-tuning details of a set of new conditions for companies seeking to join its group of customers known as “sightholders.”

According to FT.com (subs. required), the diamond giant — which sells $6 billion of unpolished gems a year and is the world’s largest supplier by value — wants traders to hold a specified proportion of equity in their businesses, so they are less reliant on bank borrowing.

De Beers, which last revised its sightholder contracts in 2011, will give companies time to make changes to their accounting practices. But sightholders unwilling or unable to do so will lose their status.

The move seeks to direct gems to the most financially sound purchasers and make the business more transparent, echoing other signs that the diamond industry is starting to modernize.

The introduction of online trading, where dealers can buy and sell parcels of gems worth millions online, is providing real-time pricing data, and represents a challenge to the old, more secretive ways of doing business, while banks that lend to the industry are demanding a more corporate approach from diamond traders and manufacturers.

Anglo American (LON:AAL) bought Oppenheimer family’s 40% ownership in De Beers for $5.1 billion in 2012, increasing its stake to 85% and ending the dynasty’s 80-year ownership. Botswana controls the rest of the business, founded by the British imperialist Cecil Rhodes
