Freshwater pearls are a popular choice in jewelry making due to their natural beauty and affordability. They are cultured in freshwater mussels, primarily in China, and come in a variety of shapes, sizes, and colors.

Pearls are organic gemstones formed within mollusks, primarily oysters or mussels. They develop as a defense mechanism against irritants, such as a grain of sand or a parasite, by secreting layers of nacre (a combination of aragonite and conchiolin) around the irritant.

Pearls are valued for their luster, which is the way light reflects off their surface. High-quality pearls have a mirror-like shine with deep, rich reflections.

• Round: The most classic shape, valued for its symmetry and uniformity.
• Semi-Round: Slightly less spherical but still quite smooth.
• Baroque: Irregular shapes with unique, often organic forms.
• Button: Flat on one side, round on the other, often used in earrings.
• Drop: Pear-shaped, great for pendants or earrings.
