Diamond
Testing
& Screening.
Advanced diamond analysis combining classical grading expertise with spectroscopic screening for natural/lab-grown determination, and type classification.
Definitive Diamond Analysis.
Our diamond testing service is built on the need for absolute certainty. We specialize in screening for lab-grown stones—whether created via HPHT or CVD processes—as well as comprehensive quality grading.
By moving beyond simple visual checks, we use advanced spectroscopy to ensure every conclusion we reach is backed by hard science.
