5-6mm Natural Freshwater Edison Pearl Loose Bead for Handmade Jewelry

Normal freshwater pearls are seedless culture technology, while Edison's pearl culture technology is to follow the culture method of seawater pearls and implant nuclear molds in the mother shells of pearls. Then, the Pearl secreted by the mother shell is wrapped in the nuclear mold layer by layer to grow into pearls. Because it is nuclear culture and the growth time is relatively long, the general time is more than 5 years, so the diameter of Edison pearls can basically reach more than 11 mm, and the roundness is very good, while ordinary freshwater cultured pearls are nuclear free culture, and the breeding cycle is only 3 to 5 years, So its diameter is generally not so large.
