Greenland Rubies

The rock formation is one of the world’s oldest, dating back 3 billion years, and it is now possible to produce the most beautiful rubies of the highest quality from here.

Rubies from the Kingdom of Denmark – a world premiere We have handpicked the Danish Realm’s very first Greenland rubies and have hand-crafted a unique and outstanding jewellery collection. Each piece of jewellery is based on the color and shape of the ruby, so that the characteristics of the gemstone are emphasised.

It is a great honour to have been chosen to introduce the first jewellery collection with Greenland rubies.

Visiting the Aappaluttoq ruby mine in Greenland was an amazing experience. To think that Hartmann’s creates jewellery that can be dated back 3 billion years – and from the Kingdom of Denmark’s own rock formations!

The world’s oldest rock formation

The mine is the oldest known ruby deposit in the world with an estimated age of
approx. 3 billion years. It produces beautiful rubies in the entire color spectrum from pink to deep red.

Several hundred years ago, local Greenlandic hunters already discovered deposits of "red stones" during reindeer hunting in the mountains, and in 1966 the Geological Survey of Denmark (GEUS) officially documented rubies in Greenland.

Greenland Ruby has now started mining the 3 billion year old stones.
The mine has been named Aappaluttoq [“Ah-puh-lu-tok”], which means red stones.

Greenland Ruby

Since 2015, the mining company Greenland Ruby has worked to build the mine, located 200 km south of Nuuk. It took more than two years to build the infrastructure and cost EUR 50 million. The mine entered into full operation in May 2017. The mine operates under very difficult climatic conditions and in a remote area that can only be reached by ship from Nuuk or by helicopter in winter. The mine mainly employs local Greenlandic employees.


CSR ‘Responsible mining’ is top of the agenda for the mining company Greenland Ruby. The mine operates to the strictest environmental and working condition regulations that exist in the world, and Greenland Ruby wants to inspire increased focus on these issues.


Certificate of Origin All Greenland rubies can be tracked from mine to market and are the first rubies in the world with certificates of origin. All rubies over 1.00 carat come with a gemmological report from the LOTUS Gemology lab in Bangkok.R

And it’s as simple as that...

In 2018, Ulrik Hartmann visited the Aappaluttoq mine in Greenland, where the world’s oldest rock formations contain the Kingdom of Denmark’s very own gemstone. It was an overwhelming experience and the start of the first Danish jewellery collection with rubies from the Kingdom’s very own underground.

Pink Polar Bear Foundation

Hartmann’s is the co-founder of The Pink Polar Bear Foundation, which is a Greenland Ruby initiative to support international polar research in the field of climate change that affect animals and humans in the Arctic region. For each piece of jewellery with Greenland rubies sold by Hartmann’s, 0.5% of the sale price will be donated to the foundation.


My journey to the world’s oldest rock formation

A Greenland Ruby Adventure

By Ulrik Hartmann

In the spring of 2018, I was on a shopping trip to Asia in search of precious gemstones, and as usual I brought along several articles about gemstones. I learned from one of them that Greenland Ruby was working on introducing the first Greenland rubies to the gemstone market. I had followed the project with interest, and I knew that the first rubies didn’t reach the market before the former mining company ‘True North Gems’ ran out of money. I also know that it requires deep pockets and great patience to extract precious gemstones.

I immediately emailed Greenland Ruby from my hotel room, and an exciting dialogue began to take shape.  The next morning at breakfast, I discussed my thoughts with my colleague Anne Mette, who was very enthusiastic about the project. And just like that, we were talking about designs and storytelling.
