Petra Sells 425-carat Cullinan Mine Diamond to BVBA for $15 million

United Kingdom – Petra Diamonds has revealed that it has sold a 425-carat diamond, which it recovered at Cullinan mine in South Africa, to BVBA for $15 million. The company took the decision to ensure a sufficient amount of cash flow in the current year. BVBA, a Belgium-based Stargems Group and Choron bought the diamond named, ‘Legacy of the Cullinan Diamond Mine’ from Petra which threw light on the quality of the ore in the mine.
Cullinan mine was bought by the miner from De Beers in 2008 to start a new life. This mine was known for giving the largest rough gem diamond – 3,106 carats, and has been popular for being the source of rarely found blue diamonds. According to BMO Capital Markets analyst Edward Sterck, the purchase price of $15 million was set as an estimation amidst the environment when Cullinan prices are decreasing on a large scale. The miner lagged the small-cap index as his shared went down by 3.8% to reach 23.90 pence by 1405 GMT.
Gia report has established that many diamond producers have been providing a variety of diamonds to the world which is why there is an increase in the popularity of various types of diamonds. Petra is dealing with the multi-million-dollar debts that it took to renew the Cullinan facility with the starting of mining at a new section of ore in the last July. But the Cullinan mine has turned out to be a profitable investment for Petra since 2008 and it would generate free cash flow in the current year. Due to the sale of the diamond, Petra Diamonds would be able to meet the target to achieve free cash flow. Petra Diamonds is likely to recover higher value stones in the quarter which would increase the pricing for Q4 more than the estimated amount. The diamond industry has been making huge progress with the introduction of new technology such as blockchain which has contributed to it on a strong note.

Mega Construction Projects That Relied on Advanced Crane Technology

When it comes to large-scale construction projects, the right equipment can make all the difference. From towering skyscrapers to massive bridges and complex infrastructure developments, cranes play a crucial role in lifting, transporting, and positioning heavy materials with precision and efficiency. As technology has advanced, so too has crane engineering, allowing for safer and more ambitious builds. In the points below, we take a closer look at some of the world’s most impressive mega construction projects that relied on cutting-edge crane technology to bring them to life.
Burj Khalifa – Dubai, UAE
Standing at a staggering 828 metres, the Burj Khalifa remains the tallest building in the world. Constructing such a colossal structure required cranes that could operate at extreme heights. Specialised luffing-jib tower cranes were employed to lift materials hundreds of metres into the air, battling high winds and desert heat. These cranes were anchored to the structure itself as it rose, ensuring stability and precision throughout the build.
Sydney Metro – Australia
As Australia’s largest public transport infrastructure project, the Sydney Metro has transformed the way people move around the city. The project required massive tunnel boring machines (TBMs) to carve underground routes, but just as critical were the cranes used to transport and position enormous precast concrete segments. Mobile and crawler cranes with advanced hydraulic systems played a key role in assembling stations and track infrastructure with minimal disruption to existing road networks.
Hong Kong-Zhuhai-Macau Bridge – China
This engineering marvel, stretching 55 kilometres across the Pearl River Delta, is one of the longest sea crossings ever built. Given its scale, floating cranes with immense lifting capacity were used to position pre-fabricated bridge sections. Some of these cranes had lifting capabilities exceeding 3000 tonnes, demonstrating the sheer power and precision required for such a complex marine project.
The Panama Canal Expansion – Panama
The expansion of the Panama Canal was one of the most ambitious infrastructure projects in recent history, involving the construction of massive new lock chambers. Gigantic gantry cranes were used to install the enormous steel lock gates, some weighing over 3000 tonnes. These cranes had to operate with pinpoint accuracy to ensure the seamless functioning of the canal’s new locks, allowing for the passage of larger vessels.
Hinkley Point C Nuclear Power Station – UK
The construction of this next-generation nuclear power plant has required some of the world’s most advanced heavy-lift cranes. The site features one of the largest land-based cranes in the world, capable of lifting reactor components that weigh hundreds of tonnes. These high-tech cranes have been crucial in ensuring the safe and efficient assembly of the plant’s intricate infrastructure.
The Role of Advanced Crane Technology in Modern Construction
Each of these projects would have been impossible without the evolution of crane technology. Innovations such as digital load monitoring, autonomous operation, and enhanced safety systems have allowed cranes to handle heavier loads with greater precision than ever before. For companies tackling complex construction projects, working with an experienced crane hire provider is essential. Businesses like Sventek Cranes offer cutting-edge crane solutions, ensuring that even the most ambitious projects can be completed safely and efficiently.
Mega construction projects continue to push the limits of engineering and design, and advanced crane technology remains at the heart of these achievements
Whether it’s lifting components for a record-breaking skyscraper or positioning bridge segments over open water, cranes will always be an integral part of building the world’s most remarkable structures. By leveraging state-of-the-art crane systems, today’s construction industry is making the impossible possible – one lift at a time.
