What we are:

PolarKoru 

Accredited gemologist and jeweler Jari Korhonen is the founder of Finland-based PolarKoru and its parent company, Zen Gems, a loose gemstones producer and supplier. 

Jari has always been very keen on minerals and gemstones.  As a young man he also dreamt of becoming a sea captain. He began his career at sea, and in the year 2000, he went to work on a Hong Kong-based cruise ship with a Burmese crew. The crewmen’s families were in the gemstone-mining industry, and Jari’s old interest for beautiful gemstones reignited. (Burma is a world-famous producer of the finest rubies and many other gemstones.)

Jari studied gemology at the Asian Institute of Gemological Sciences and graduated in 2004. Later he continued his studies to earn a diploma in Jewelry Design. In 2006, Jari founded PolarKoru to create bespoke jewelry that combines high-quality colored gemstones and innovative design. 

Many of PolarKoru’s design inspirations come from northern nature, with its diverse forms and beauty. Ideas often come from the simple things, such as the contrast of stones and the placid surface of a lake. 

PolarKoru’s strength in the growing jewelry market is its selection of high-quality gemstones and its very personal, tailored service.

Our Gemstones 

We have a passion for beautiful gemstones.  Because our parent company, Zen Gems, is a major producer of loose gemstones and has supplied within the trade for many years. our prices and our selection of high-quality gemstones are second to none.

Our in-house gemologists carefully select our stones directly from the cutting facilities, and our stones are often cut from rough stones right from the mines. Buying from us means buying from the source without any middlemen.
