Information

Diamonds and gemstones are the only thing that you will buy where the difference in price or value is dependent on microscopic examination.   Although machines are being developed to take the human factor out of grading, gemological science is still mostly dictated by human observation.  Education and experience are important for accurate grading.

To learn the terms and criteria for grading diamonds and colored stones, select the appropriate category from the drop down menu associated with "Information".
