NACRE: |
||
|---|---|---|
| The silky substance secreted over a "bead" to form a pearl. Layer after layer of nacre builds up to form the pearl. When viewing a pearl in good lighting, light travels through all layers of nacre, and each microscopic crystal reflects the light like a prism, creating an iridescent effect. The thicker and more lustrous the nacre, the more valuable the pearl. | ||
