What you need to know?

• How are ECO4 Lab Grown Diamonds made?

  ECO4 Lab Grown Diamonds are produced by utilizing two gem-quality diamond creation processes: High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD). In both processes, a small diamond seed is placed in an environment that contains carbon. Under suitably controlled conditions, the diamond grows, atom-by-atom, layer-by-layer, recreating nature’s process.

• Is the process patented?

  Yes. Lab grown diamonds can only be grown through two processes: high pressure, high temperature (HPHT) and chemical vapor deposition (CVD). ECO4 Lab Grown Diamonds are grown through a CVD process called Microwave Plasma Chemical Vapor Deposition.

• Are your diamonds graded?

  Yes. All ECO4 Lab Grown Diamonds are graded to the exact same standards as earth mined diamonds. They come with a certification by leading independent gemological laboratories such as the International Gemological Institute (IGI), the Gem Certification & Assurance Lab (GCAL), and the Gemological Institute of America (GIA). These certifications are the same ones that earth mined diamonds use and have a detailed description of the grading results of the 4C’s. It will also provide you with a full disclosure of the grown diamond origin and the certification number that is laser inscribed on your diamond.

• What is the appraisal process?

• What quality are the diamonds you offer?

  Our ECO4 Lab Grown Diamonds come in a variety of color and clarity grades just like earth mined diamonds! They are made from Type IIa rough, which is the rarest and purest form of diamonds in nature. When a diamond is mined from the earth, no one knows what grade it will be. Similarly, no one knows how an ECO4 Lab Grown Diamond will be graded until it has completed the growing cycle. Earth mined diamonds can come with all sorts of color tints, as they are affected by other minerals and materials surrounding them in nature. The most common tints you will see are shades of yellow. These are caused by trace elements of nitrogen when the diamond is formed. However, when an ECO4 Diamond is grown in the lab, the other non-diamond elements are removed. This absence of nitrogen causes the lab grown diamonds to appear whiter than an earth mined diamond of the same color grade.
