✨ What Gives Pearls Their Lustre?

Ever wondered what makes pearls shine with their natural beauty? 🤍

A pearl’s beautiful lustre comes from thousands of microscopic layers of nacre, composed primarily of aragonite and conchiolin. These layers interact with light, creating the soft glow, shimmer, and iridescent beauty that make every pearl unique.

At IIGJ Lab, we help you understand the science behind the beauty of pearls through professional pearl identification and testing.

Discover the science. Understand the beauty. Trust the expertise.
