When people first see a beautiful pearl, they often notice its glow before anything else. That glow is called luster.
Luster is the soft, living reflection that appears on a pearl's surface. It is not simply shine. A pearl with strong luster can seem to hold light beneath its surface, creating depth, clarity, and a sense of movement as you wear it.
When comparing pearls, look for reflections that appear clean rather than cloudy. Notice whether the surface seems bright and crisp, or soft and diffused. A pearl does not need to be perfectly round to be beautiful; in fact, unusual shapes can be full of character. But luster is often what gives a pearl its unmistakable presence.
The pleasure of pearls lies in these small details. Their beauty is never loud. It reveals itself slowly-in changing light, in close conversation, and in the simple act of wearing them often.
