Finest materials

At Ro Copenhagen, we see jewellery as something very personal – beautiful mementos that hold memories, meaning and stories.

The Noble Metal
At Ro Copenhagen, we have a passion for quality jewellery produced in 18kt gold.
By using premium materials, the joy and sentiment of Ro jewellery is given longevity.
We have chosen to use only 18kt yellow and white gold, because this noble metal develops a very special patina, forming a more refined finish over time.

Pure gold is measured as being 24/24 karats. 24-karat gold is soft, and therefore we alloy pure gold with other metals such as silver, copper and palladium.
18kt gold is stamped 750 (750/1000), which means 18kt jewellery is made from 75% pure gold.

Glittering diamonds and enchanting gems have long fascinated us, and their history makes them no less impressive. Gems are one of nature’s wonders. Chemistry, temperature and time are essential forces which determine a stone’s nuances and variations. At Ro, we believe each stone is beautiful in its own unique way.

About 200 km below the Earth’s surface, carbon atoms are crystallised and form a diamond structure.  
The marvelous creation of diamond takes millions of years under immense heat and pressure, which is exactly why they are valuable and rare.
A diamond stone’s value is based on the four C’s: carat, colour, clarity and cut.

At Ro Copenhagen, we use some of the finest diamonds, all of which are carefully selected by gemological specialists (G-VS). Diamond and gemstones in Ro Copenhagen’s jewellery are of natural origin, they are purchased conflict–free from official dealers in accordance with UN resolutions.
A signature diamond is found in all Ro jewellery – sometimes this diamond is so discreet that it is barely discernible, but our unique diamond hallmark is present in everything we do.
