Are Chatham Created Diamonds guaranteed?
Yes. They are guaranteed for life against chipping and breaking under ordinary circumstances. Q: How do I know the quality of my diamond? greenKarat obtains a grading report and appraisal from The European Gemological Laboratory (EGL) or Gemological Institute of America (GIA) on every diamond of ½ carat or more. This report is available for your review at their respective websites, and will be included when we send you your diamond ring.
