Our Precious Gemstones

We have access to some of the finest precious gemstones in the world.  


Our precious gemstones are sourced from the most respected and renowned gem producing regions of the world such as Sri Lanka for Sapphires, Mozambique for Rubies, Colombia for Emeralds.


Our semi-precious and precious gemstones including diamonds are 100% natural and known to be conflict-free and each having its own unique luster and characteristics, in order to be selected as a KTC jewel.


We hand-select the appropriate high quality gemstone to be made into Kohn Trading Co.’s jewelry.  Our jewelry pieces are not mass produced and are completely one-of-a-kind in gemstone and in craftsmanship.
