Pearls are usually considered to be the best friend of women that are found in a variety of shapes, sizes and colors. Real pearls that are available at some of the jewelry stores are either formed by natural or cultured means through mollusks that are found in salt and freshwater. Natural pearls are usually expensive than cultured, but the ‘hard to find’ factor is not alone responsible for their cost. There are various other reasons that make them expensive and highly popular among people. Natural pearls are usually those that are formed inside the mollusk without intervention of people. The chances of finding such gems in freshwater is extremely low and hence for the same reason the jewelry stores are flooded with cultured pearls. These pearls are also formed naturally, with the only difference that the pearl farmer coaxes the process along by placing the proper ingredients into the mollusk to naturally form a perfectly shaped gem.
Seed pearls are a type of gem that looks like a small poppy seed. There are usually oval in shape with a few distortions. This type of gem is usually found in necklaces and also in some of the decorative hair pieces. Due to the small size of these pearls, there are many people that prefer them to portray a small yet effective jewel. Freshwater seed pearls is again a category of this precious gem that is usually grown inside mussels or oysters in rivers, ponds and lakes that are filled with fresh water. They are usually less expensive than saltwater pearls that are considered to be durable and most commonly found in irregular shapes. Moreover, they are available with slight variations in color, size and character. Seed pearls that are formed in freshwater also do not have a nucleus and are composed entirely by nacre.
