Natural Diamond Report
IGI Natural Diamond Reports give an accurate assessment of a diamond’s cut, color, clarity and carat weight according to strict international standards.
Hearts & Arrows Report
“Hearts & Arrows” (H&A) diamonds are cut so precisely that their facet reflections overlap when viewed in a reflective scope. The reflections resemble a pattern of “hearts” seen face-down and “arrows” face-up. Hearts & Arrows precision is typically associated with Excellent-Ideal cuts of superior quality.
