Inclusion 'surfacing over time' My engagement ring was purchased at a major retailer years ago and I've followed the guidelines of the warranty. After the last visit I noticed a mark in the center stone. The store's jeweler said it was a fracture but the corporate jeweler said it was an inclusion and upon further correspondence, it was an inclusion that wasn't evident when originally purchased but that inclusions 'surface to the top of the diamond with time' (direct quote). Is this a thing that's even possible?
