Description

The akoya pearl is a saltwater cultured pearl from the akoya oyster. Akoya are considered to be the classic pearl used for necklaces and other pearl jewelry. Nacre is the material of which pearls are composed and consists of aragonite crystal layers separated by conchiolin, a protein secreted by mollusk shells. The thickness of these layers determines the color of reflection from the nacre. The transmission interference color is complementary to the reflection interference color.

These reference values are based on the most accurate data available at the time and are continually updated as new measurements become available. Depending on the material and the property you're after, there's more or less variability to take into account. Use these values as a starting point, or as validation for existing materials, and then tweak further using your artistic freedom.
