Diamond Education – The 4Cs


Jensen Jewelers is Grand Rapids jeweler for Engagement Rings and Diamonds.

At Jensen Jewelers we adhere to GIA (The Gemological Institute of America) diamond grading standards. They are the ones that invented the grading system that jewelers use worldwide! All of our staff gemologists have been trained by GIA and we employ an in-house GIA Graduate Gemologist, which is as good as it gets! What better way to learn about the 4Cs than directly from the source. Please click on the following link and enjoy the 4Cs education right from GIA:
