[INFOGRAPHIC] Top 10 largest diamonds ever discovered
It’s unanimous: the world loves diamonds. These sparkly jewels have become a staple of wealth, commitment and beauty, as told through catchy slogans like ‘diamonds are forever’ and the notion they’re a girl’s best friend (this one is a fact).
Because the majority of extracted diamonds are small in stature, we decided to showcase the top 10 largest ever.
10. The Millennium Star – 203.04 carats
Discovered in the Democratic Country of Congo in 1990, this 203.04 carat diamond was purchased by De Beers soon after. It took Ascot Diamonds, a member of the Steinmetz Group of Diamond Companies, roughly three years to cut and shape.
The late De Beers Chairman Harry Oppenheimer famously stated: "it is the most beautiful diamond I have ever seen."
9. The Red Cross – 205.07 carats
Renown for its canary yellow coloring, Red Cross diamond was discovered in South Africa at De Beers mine in 1901. This massive, 205.07 carat cushion shaped gem is one of the rarest diamonds on this list.
8. The De Beers – 234.65 carats
With a name like De Beers, you know it’s a winner. Discovered in South Africa in 1888, the De Beers is the largest diamond recovered at its Kimberly complex. Weighing 234.65 carats, the De Beers is the eighth largest diamond in the world.

In a tale of fate, the Incomparable was found in 1984 by a small child that was playing next to a pile of debris from the nearby MIBA Diamond Mine in the Democratic republic of Congo. The value of the diamond is estimated to be worth $20 million.
2. The Cullinan I – 530.20 carats

Deloitte predicts industry transformation - Tracking the Trends 2019 report
Deloitte has published the eleventh edition of its annual report on the mining industry. Tracking the Trends identifies the top ten trends transforming the future of mining in 2019
The Deloitte report endeavours to provide the mining industry with insights it can leverage to support its continued quest for productivity, capital discipline, strategic development and sustainable growth.
Philip Hopwood, Deloitte’s Global Leader - Mining & Metals, commented: “It appears that the mining industry is poised for greater growth than it’s seen in a decade, but today’s market realities are very different than those of the past. We’re now dealing with geopolitical tensions in the form of trade wars and tariff concerns, as well as looming asset shortages. Rising commodity prices should fuel expansion, but could also result in a return of inflation and the costs that go with it, eventually eating into margins.
Disruption and volatility has become the new normal and the pace of change is outpacing our ability to adapt. This makes it imperative for mining companies to clarify how they plan to drive value into the future and how they intend to respond when prices inevitably drop again.”
Here are the key messages provided by the 2019 report:
- Disruption and volatilitymake it imperative for mining companies to clarify how they plan to drive value into the future and how they intend to respond when prices inevitably drop again. To thrive into the future, mining companies will need to challenge the status quo by soliciting a diversity of opinions and taking the risk to do things differently.
- Technology and artificial intelligence (AI) will play a key role, not only in helping companies envision future scenarios, but in identifying risks at an enterprise level and transforming the supply chain. Moreover, advances in finance platforms, sensor technology, autonomous vehicles, cloud- based solutions, and analytics are paving the way for the design of a digital mine.
- Understanding the needs and perceptions of people both inside and outside the organization will be critical. Companies must build a more diverse workplace and address succession planning, while fostering loyalty and retention among existing employees. At the same time companies must do more outreach to local communities, governments, and consumers so they can be more transparent and receptive.
Top Ten Trends Transforming the Future of Mining:
- Rethinking mining strategy - Embedding the discipline to deliver measurable value across the cycle
- The frontier of analytics and artifcial intelligence- Moving up the maturity curve
- Managing risk in the digital era - Exploring a new approach to controls and risk management
- Digitizing the supply chain - Why innovation requires integration
- Driving sustainable shared social outcomes - Finding value beyond compliance
- Exploring the water-energy nexus - Making the case for a systematic approach
- Decoding capital projects - Learning from past mistakes
- Reimagining work, workers, and the workplace - A blueprint for the future
- Operationalising diversity and inclusion programs - From theory to practice
- Demanding provenance- EVs and battery minerals provoke the desire for provenance
