It is a great honour to be able to tell this unique story. The beautiful and intense colour of the rubies is close to our hearts and knowing that the gems in some way reside in the Danish DNA makes me both proud and humble – we are rooted in a billion-year-old history.
Hartmann’s high-quality diamond jewellery
We collaborate with mining companies and diamond dealers from around the world and handpick only the best diamonds. The relationships have been built over several decades, giving us great insight, knowledge and many benefits.
We trade directly and therefore cut intermediary costs – and this is reflected in the price when you compare diamonds of the same quality.
Our diamond jewellery
Exclusive and classic diamond jewellery in the shop in Bredgade. The diamonds are handpicked at diamond auctions and from mining companies worldwide.
We sell jewellery that will inspire and create long-lasting joy. Jewellery that can be passed down to the next generation, and that carries a story.
