Post Fancy yellow diamond
Hello
Fancy diamonds such as yellow diamonds are handled and graded differently than clear diamonds, and some of the most famous diamonds in the world, such as the Hope Diamond, are fancy diamonds. Natural yellow diamonds are extremely rare, and the color is usually caused by nitrogen impurities that appear while the diamond is being formed. More commonly, yellow diamonds are synthesized in the lab; lab-made diamonds are chemically indistinct from natural diamonds, and are widely used in ornamental jewelry and some manufacturing processes.
Thanks
