About us

History of 44+ years

Scandianavian Diamond Exchange was founded in 1977, and started out as a wholesale company trading in polished diamonds and precious stones.  The company has since then expanded over 3 generations and supplies today a large variety of colored gems, natural diamonds, jewellery, estate-jewellery and watches.  SDE also offers gemological services (GIA), appraisals (NGF), hand- and laserengraving, jewellery findings, settings and CAD/CAM services directly to the public.  Our skilled workshop team consists of cerified GIA / HRD gemologists, master-goldsmiths, engravers, diamond/stone-setters and a master-watchmaker!  We look forward to welcoming you in our store, for your next jewellery and watch investment or service!


SDE's passion and focus are to unveil the true art that lies behind every piece of jewellery. By macro photography and video, we strive to show the beauty and skills that lie behind every unique piece that is made.  We create new designs every week, by hand and 3D printing, and we hope our designs will make your glamourous side intrigued right down to your soul!   SDE also restores estate (antique/vintage) jewellery & watches on a daily basis. We bring Pre-Owned-Art back to life so they can be treasured by their rightful new owners for years and generations to come! This way we are also contributing to reducing emissions of carbon dioxide, and minimizing human carbon footprint on mother earth ❤️ Over 80% of new SDE jewellery is now made from recycled and refined precious metals! We are here to create!
