SARINE LIGHT™
Sarine Light Performance Diamonds
The Global Standard in Diamond Light Grading
Sarine Light™ is the global standard in diamond light performance grading. Unlike traditional 4C grading, which measures only a diamond's natural rarity, Sarine Light uses precision instruments to measure the optical performance a diamond actually reveals after cutting — the sparkle and fire visible to the naked eye. Every CathyPaul diamond is checked against both Sarine Light optical grading and GIA 4C standards, so what you choose is both rare and radiant.
