Lab grown diamonds are 100% real diamonds formed above ground instead of in the earth. Scientists use pure carbon seed crystals placed in high-tech growth chambers that recreate the conditions which diamonds form in nature. Carbon slowly deposits onto the seed crystal in these chambers and over time, form a rough diamond crystal. Those crystals are then cut and polished in the exact same way that diamond rough mined from the earth is. The only difference between a diamond mined from the earth and one grown in a lab is its origin. Because they have the same physical, optical, and chemical properties, your lab grown diamond from Taylor Custom Rings will look and hold up exactly the same as a diamond mined from the earth. And you can feel great knowing it's a mine-free diamond!
