The nucleus is a round ball polished from the shells of the Mississippi River, with the same chemical composition and structure as a natural pearl. After being implanted, the oysters are returned to the sea to create pearls according to the natural process.
- Nourishing / Husbandry : Maintaining the health of oysters is the key to producing high-quality pearls. During the 2-3 year rearing period, oysters are cleaned individually every 10-14 days, to remove harmful marine organisms.

Pearl quality according to the classification system “The Five Virtues”
Luster - Pearl Shine
Pearl luster or "water" pearls are evaluated based on the refraction of light when interacting with the numerous shells of the pearl. The "Nacre" mother-of-pearl shell is the organic pearly material produced by the oyster bodies, forming the pearl body.
Pearl quality is good when the oyster creates a pearl with a perfectly symmetrical mother-of-pearl layer that allows light to be completely refracted when passing through the pearl shells.
This reveals the appearance of a cool occasion sparkle from deep within the jewel. Natural sheen is permanent and should not be confused with the sheen of treated pearls, which lose their shine over time.
High-quality pearls exhibit a phenomenon called "orient" - a beautiful nacre luster due to the delicate combination of colors on the pearl's surface: "pearl transparent lustre" and the jewel color "pearl color".
