At EX3 Diamond, we make lab-created diamonds to improve the accessibility and quality of diamond engagement rings. Over the past 15 years, we have perfected the process of making certified lab-grown diamonds to deliver excellence in stone quality, including color, clarity, and cut for earrings, wedding bands, and more.
While our process for creating loose lab-grown diamonds may be simple, our equipment and materials are cutting-edge. With sophisticated machinery to mimic the heat and pressure of the Earth’s crust, we’ve cut down the timetable for naturally developed diamonds in an eco-friendly, cruelty-free, controlled laboratory.
Our EX3 created diamonds have the same crystal structure, brilliance, and weight as earth-mined diamonds – the only difference being that one was made deep in the earth and the other in a laboratory. The end result is the same – down to the last atom!
After our certified lab-grown diamonds are finished being created, we facet and polish the rough tetrahedron carbon rock into a sparkling diamond.
We follow strict cutting standards while maximizing total diamond weight to ensure ideal cuts for every stone. We closely scrutinize our created diamond cuts to deliver the most sparkle and brilliance possible.
Before we add them to our inventory, the International Gemological Institute (IGI) tests, analyzes, examines, and laser inscribes every single loose lab-grown diamond to ensure its quality and sustainability.
Using professional gemological equipment, our created diamonds are almost impossible to differentiate from natural diamonds. Lab-grown diamonds are physically, optically, and chemically indistinguishable from natural diamonds! They can only be identified with extensive scientific testing using specialized equipment.
Just as in nature, our lab process creates variation with each diamond.
No two diamonds are exactly alike, each has its own unique characteristics.
We create high-quality diamonds with brilliant sparkle and shine.
Ethical sourcing makes our diamonds eco-friendly and cruelty-free.
Our stones are visually and physically identical to mined diamonds.
Lab diamonds offer excellent value and are less expensive than natural diamonds.
We are on a mission to do less harm to our environment and to help reshape the diamond industry. With our SCS certification, you can rest assured that every ring in our store uses exclusively recycled materials and lab-created diamonds and gemstones to ensure socially and environmentally ethical sourcing. We take our accountability seriously.Learn More
