Färskvattenspärlor

Färskvattenspärlor are pearls that are formed within freshwater mussels. Unlike saltwater pearls which are typically found in oysters, freshwater mussels live in rivers, lakes, and ponds. The process of pearl formation in a freshwater mussel is similar to that in saltwater oysters. When an irritant, such as a parasite or a small piece of tissue, enters the mussel's shell, the mussel begins to secrete nacre, a lustrous substance made of calcium carbonate, around the irritant. Over time, this layer of nacre builds up, forming a pearl.

Freshwater pearls are generally more abundant and less expensive than saltwater pearls. They come in a wide variety of shapes, sizes, and colors, including white, cream, pink, lavender, and even green or blue. Common shapes include round, oval, baroque (irregularly shaped), and rice-crisp. While perfectly round freshwater pearls are rare and highly prized, the unique shapes of baroque pearls are also sought after for their individuality.

The quality of a freshwater pearl is assessed based on several factors, including luster, surface cleanliness, shape, and size. Luster refers to the shine and glow of the pearl, while surface cleanliness describes the presence or absence of blemishes. Due to the controlled farming methods now employed, freshwater pearls often exhibit a high degree of luster and a relatively clean surface. They are widely used in jewelry, from simple pearl necklaces and earrings to more intricate designs.
