What does "Indented Natural" mean?
A concave or dented pitted area on the diamond's surface that is still part of the original rough diamond; it is left unfaceted (to retain the diamond weight) and unpolished. Indented naturals can be considered blemishes depending on their size and location. Many indented naturals have a triangular appearance or parallel grooves.
