About lab-grown diamonds

A. Lab-grown diamonds are real diamonds that are created in a lab. Compared to natural diamonds that take a long time to be created underground, diamonds are attracting attention as a new era diamond that is ethical and has excellent cost performance.

However, there are some people who actively choose lab-grown diamonds because of the cost advantage and ethical perspective. If you are unsure which one to set, please contact customer service.
