Global Gemstones Solutions

Gemstones are objects that inspire some of the greatest human emotions: love, commitment, beauty, power. To maintain this alluring image it is vital that these products be sourced ethically and responsibly. We partner with firms in the mining, manufacturing and distribution sectors to create business models that capitalize on ethically sound business practices.



Our extensive expertise in the diamond and jewelry business begins in the laboratory setting. From there we have partnered with companies and industry bodies to establish new labs globally. By leveraging our extensive knowledge of the world inside the gemstone we create new business ventures in the world outside the gemstone. Our clients come from five continents and we have traveled the world with sophisticated equipment as cultural ambassadors of the jewelry trade.
