This journey begins in a diamond cutter’s office with our inspection of rough diamonds, partially faceted diamonds and fully finished cut diamonds. First and foremost, diamonds are inspected for the quality of how they are cut. Underwood’s Certified Gemologists, C. Clayton Bromberg and R. Michael Richards, are the only diamond buyers known by the diamond-cutting community to use the Angular Spectral Evaluation Tool (ASET) which allows the viewer to evaluate a diamond’s light performance. Once diamonds are selected for their quality of light performance they are sorted two more times: first for color and second for clarity. Underwood’s exacting standards are then verified by one of two diamond grading laboratories: The Gemological Institute of American (GIA) or the American Gem Society Laboratory (AGSL). At this point these diamonds are sent to Jacksonville for final examination in our own American Gem Society (AGS) Accredited Gem Lab.
