Freshwater pearls are produced in rivers and lakes, most of production today comes from China where is better technology and cultivation methods have been developed. With low labor costs, China can produce less expensive pearls which offer many different beautiful natural colors such as light, medium and dark orange, lavender and rose gray . Custom colors are found in yellow gold, olive green, gold, gray, blue and bronze. Freshwater pearls have mostly no nucleus, they are totally nacre. It takes one to two years to produce. 10 years ago most of the pearls where of rice shape, wrinkled and of rather small size but today we found beautiful pearls up to 10 mm and in very rare cases even bigger. The bigger they are in size the lower quantities are available in good qualities. Qualified freshwater pearls are specified by luster, smoothness, size and shape.
