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.


Rubies from Greenland
Rubies are considered to be the rarest and most precious of all gemstones
- and they have historically adorned the crown jewels and exclusive jewellery throughout the world.
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
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 certificate of origin from Greenland. All rubies are heat treated.
And it’s as simple as that...

My journey to the world’s oldest rock formation
A Greenland Ruby AdventureBy 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.
