This curriculum is designed solely to train professionals in modern visual and digital diamond evaluation for e‑commerce and retail environments. It does not replace formal gemological education, certification, or laboratory‑based training. Visual estimation techniques taught in this course do not substitute for the precise measurements, chemical testing, or plotting performed by calibrated laboratory equipment or official grading bodies (including but not limited to GIA and IGI).

The techniques taught in this course are designed to enhance professional visual and digital evaluation skills. As with all visual‑based assessment methods, results depend on the practitioner’s judgment and the specific conditions under which they are applied. Students are responsible for any evaluations or representations they make in their professional practice.
