Sarine Light Diamonds

Sarine Light is a diamond light-performance grading technology developed by Sarine, an Israeli company. Using precision instruments, it measures a diamond's brilliance, fire, sparkle and light uniformity under real-world conditions, providing objective data for a diamond's "beauty".

Why is light performance needed beyond the 4Cs?

The traditional 4Cs (carat, colour, clarity, cut) describe a diamond's physical specifications, but cannot fully tell you how much a diamond actually sparkles. Two diamonds of the same 4C grade can have very different light performance in practice. Sarine Light fills this gap, helping you choose the diamond that truly shines the most.

The diamonds carefully selected by CathyPaul Diamond come with GIA international certification to guarantee quality, plus a Sarine Light performance report for double assurance, so you can buy with confidence.
