The Enigma Black Diamond | A Rare Cosmic Wonder. News, 25th January 2022

"The Enigma" is a 555.55 carat diamond that GIA laboratory graded Fancy Black in GIA Colored Diamond Identification and Origin Report. This diamond will be placed for auction at Sotheby's on February 3rd. 

Much more than a jewel. A treasure from interstellar space. “The Enigma” is an exquisite and extremely rare black diamond formed billions of years ago. This latest video showcases the 555.55 carat black diamond, offered by Sotheby's (3 – 9 February | London).

This unearthly stone is a carbonado diamond that possibly came from outer space, either created through meteoric impact or brought to Earth by an asteroid.

Unlike most diamonds, carbonado is a naturally occurring polycrystalline diamond material composed of randomly oriented cuboidal microcrystals. It contains non-diamond carbon material that gives it a generally black, gray, or brown appearance. Some data indicates that carbonado is slightly tougher than conventional monocrystalline diamonds.

Kyndykan has become a symbol of the resilience, spiritual strength and unique values of the indigenous peoples of the Far North. The story inspired ALROSA to support a project also named Kyndykan, which aims to draw attention globally to the problem of preserving the traditions and culture of the indigenous peoples.

The Kyndykan diamond has a yellow-brown colour and measures 25х16х22 mm. It was mined in 2021 at one of the alluvial diamond deposits at Diamonds of Anabar, a subsidiary of ALROSA which operates across the vast Arctic territory of Yakutia. The indigenous peoples of the North traditionally inhabited this region. The diamond was found in the Olenyok district, one of the coldest regions in the northern hemisphere.

ALROSA first announced its support for the Kyndykan project in September 2021. This was the latest step in the company’s efforts to preserve the historical values of the indigenous peoples of Yakutia. Since its establishment, ALROSA has been involved in the lives of indigenous peoples, supporting ancestral deer-herding and fishing settlements, training communities in various specialties, creating jobs, providing everything necessary for a fulfilling life, organizing ethnic festivals, and supplying products to remote villages.

Evgeny Agureev, Deputy CEO of ALROSA said: “At ALROSA, we have a great tradition of giving names to newly mined diamonds. On this occasion, we decided to name a diamond mined in the Far North in honour of the little Even heroine Kyndykan and after a wonderful project, which is doing a lot to ensure that voices of indigenous peoples of the North are heard. ALROSA has always admired their resilience and strength of character, rich history and age-old traditions. Our common goal is to preserve all of this for future generations and to tell this story to the world.”

Gemfields introduces its largest high-quality emerald yet – Chipembele, the rhino emerald. News, 23th December 2021

Gemfields is delighted to introduce “Chipembele”, the latest and largest significant gemstone discovered at the Kagem emerald mine in Zambia. Naming of uncut emeralds is a tradition reserved only for the most rare and remarkable gems. While no official record exists, it is thought that not more than a couple of dozen gemstones have ever been given their own name, and it is extremely unusual to encounter a gemstone weighing more than 1,000 carats. Weighing 7,525 carats (1,505g), Chipembele – which means ‘rhino’ in the local indigenous dialect of Bemba – has earned a place in this exclusive club, and a name to match. 


The discovery of Chipembele follows Insofu (Bemba for ‘elephant’ – discovered in 2010) and Inkalamu (‘lion’ - 2018), all of which were formed within relatively close proximity at the Kagem emerald mine in Zambia, which is the world’s single largest producing emerald mine, owned by Gemfields in partnership with the Zambian government’s Industrial Development Corporation. 

Chipembele was discovered on 13 July 2021 by geologist Manas Banerjee and Richard Kapeta (who was also the team leader for the discovery of Inkalamu in October 2018) and his team at Kagem. The discovery, they said, “left everyone speechless”. Kapeta shouted in joy, “look at this rhino horn!” And hence, the gemstone found its name. 

Chipembele formed under near perfect conditions, allowing the combination of the elements beryllium, chromium and vanadium to crystalise into large, distinct hexagonal crystal structures with glassy surfaces. 

The recovery of such a large high-quality emerald is extremely rare and was made possible by the skilled Kagem mining team, who practise gentle extraction techniques when mining in areas where emerald mineralisation is present. The rich, golden green hue and gemmy nature of this emerald will be appealing to buyers looking to yield fine quality faceted emeralds after the cutting and polishing process.

Fura Gems hosted its first sales event for rough Mozambican rubies in August and September 2021. The international gem mining and marketing company has assets in Colombia (emerald), Australia (sapphire), and Mozambique (ruby). After previous sales events for Colombian emeralds in the first months of 2021, the firm now offered its rubies to the trade for the first time. - Gia.edu

Mozambican rubies have been available in the trade since 2009, and the region quickly became one of the most important sources for the red variety of corundum. Fura is only the third company to bring rubies to the trade in a formalized tender. During the first years after the deposit’s discovery in 2009, gems were recovered by artisanal miners and traded locally.

In 2014, the first large-scale sale of Mozambican rubies by an organized mining group took place. During that tender, Gemfields offered nearly two million carats of rough ruby, and they have hosted 14 auctions since then. Mustang Resources hosted a rough ruby tender in 2017, which was not well received by the trade. Fura took over existing ruby mining permits and equipment in Mozambique from various companies, including Mustang Resources, acquiring the largest ruby mining license in the country.

Invited buyers were able to view Fura’s rubies in Jaipur and Bangkok, locations that host the largest colored stone manufacturing industries in the world. Each company was able to view the stones over two days in a secured space. Precautions against COVID-19 included a limited number of attendees per day, which caused the entire event to last more than 24 days across the two locations. This allowed all potential buyers ample time to inspect the rough rubies.
