Pure History Of Creation

Our Pure diamonds only use a modest amount of electricity and resources. All diamonds we offer are grown in controlled facilities by trained engineers, scientists and technicians. They are cut by skilled cutters, and fully disclosed and identifiable as pure product. Our diamonds are origin-guaranteed.

Diamond creation process is one of the most precise and difficult manufacturing techniques that humans have ever achieved. It took almost 60 years to develop the precision to grow gemstone quality diamonds larger than one carat.

Today Pure diamond growing process results in a diamond that is actually superior in overall color and clarity to most earth mined diamonds. HPHT technology has come so far that now it is possible to produce up to 10 carat diamonds delight of gemologists, jewelers and diamond connoisseurs around the world.
