Know where you stand, get your diamond appraised!
The acquisition of a diamond or precious gemstone can be an important expression of love or accomplishment that simultaneously represents a major investment. It is essential for a diamond proprietor to have certification of the characteristics of the diamond in order to obtain confidence in the integrity of what they have acquired. An IGL Diamond or Gemstone Certificate is a statement issued by one of our independent gemological laboratories documenting the characteristics of the stone as determined by our experienced diamond graders at the time of evaluation.
