Lustre is the most important characteristic of a pearl.

A pearl consists of countless layers of pearlescent organic material known as ‘nacre’. Lustre arises from the interaction of light with these layers of nacre. The highest quality pearls have a mirror-like lustre showing a high level of reflection. A pearl with deep and radiant natural lustre is desirable and valuable whatever its shape, colour or size and despite any surface imperfections.
