Freshwater Pearl

Perhaps the best-loved gems of all time, pearls—both natural and modern cultured pearls—occur in a wide variety of colors.


Freshwater pearls are the most commonly produced pearls, and they are one of the most popular pearl types among shoppers and jewelry designers. This is due to their remarkable range of sizes, shapes and colors and their commercial availability at competitive prices.

They are usually cultured in freshwater lakes and ponds, often with many pearls grown in one oyster.

  • SIZE

    Cultured pearls range from 2-16mm in diameter, depending on the mollusk used.


    Spherical pearls are the most valued but symmetrical drops are also sought.

  • Luster

    Pearls with high luster have sharp bright reflections on the surface.


    The number of blemishes on a pearl's surface is evaluated to judge quality.


In general, the larger the pearl, the more valuable it is. Different varieties come in different sizes: South Sea cultured pearls are the largest.


Round is the most difficult shape to culture, making it the rarest cultured pearl shape and—if all other factors are equal—also generally the most valuable. There are exceptions, though. Well-formed pear, oval, or baroque (irregularly shaped) cultured pearls are also prized by pearl lovers. Different pearl types are held to different standards when classifying
shape. Japanese saltwater cultured pearls are held to the strictest standards for shape.


Of all pearl quality factors, lustre might be the most important. Lustre is what gives a natural or cultured pearl its unique beauty.

Aslowe only uses pearls with very good or excellent lustre.


Like colored stones, most pearls never achieve perfection. Some might show abrasions that look like a series of scratches on the surface, or a flattened section that doesn’t affect its basic shape, or an irregular ridge that looks like a crease or wrinkle.

If surface characteristics are numerous or severe, they can affect the durability of the pearl and severely depress its value. Surface characteristics have less effect on the pearl’s beauty and value if they are few in number, or if they are minor enough to be hidden by a drill-hole or mounting.
