A perfectly smooth surface without imperfection is exceptional.

The process last 2 years. The pearl may have extraordinary colors declining to infinity: Pink, Turquoise, Pistachio, Peacok, Green Lagon, Blue Pacifique.

The Luster is the way the pearl is shining. It is how the light hits the surface of the pearl. We call it the Mirror Effect.
More the pearl shines more the pearl has a high mother of pearl thickness.
Le Service de la Perliculture (attached to the Ministry of the Sea) will reject all pearls with a low luster
