1. Freshwater versus Saltwater
At The Pearl Girls we absolutely love freshwater pearls. Although we use some saltwater pearls in our
pieces, we love freshwater because they are the closest rival to natural pearls. We know that some
people misunderstand freshwater pearls. After Mikimoto started culturing saltwater pearls in the early
1900s, he tried the same process in freshwater yet he could not produce gem quality pearls! The
freshwater pearls looked like pieces of rice. So, the name freshwater pearls became synonymous with
off sized, lower quality pearls. How times have changed!
World War II halted the efforts to culture freshwater pearls in Japan and led to the Chinese taking over
perfecting this process. They have come leaps and bounds in the past decades producing large, beautiful
and round freshwater pearls. So, what is the difference in freshwater and saltwater pearls? To answer
this, we turn to Pearls: A Natural History which was a huge exhibit on pearls at the American Museum of
Natural History. Unfortunately, this exhibit is no longer available but the book from the exhibit remains
a valuable resource.
Although the composition of pearls remains the same, there are five differences in the process of
culturing freshwater pearls versus saltwater pearls. First, to get the freshwater mussels, their larvae
must survive. This is a difficult process because the larvae attach to a fish host before they
metamorphose. So, survival of the mollusk becomes an issue of culturing fish as well as the mussels
used for pearls.
Inside the saltwater oyster or the freshwater mussel, the placement of the nucleus is different. In
saltwater pearls, a bead or shell is inserted in the gonad of the oyster. This is not possible in freshwater
mollusks because of its different composition. In freshwater mollusks a small piece of tissue is placed in
the soft mantle tissue which lines the shell. A piece of shell would never fit in this thin lining so a piece of
tissue is used instead. This leads to our third difference..
I have said before that freshwater pearls are the closest rivals to natural pearls. Because the nucleus is
just a piece of tissue, these tissue-nucleated freshwater pearls are 100% nacre and are difficult to
distinguish from freshwater pearls which have no nucleus at all. They are all pearl and tend to be heavier
than their saltwater counterparts.
Freshwater pearls can be nucleated many times meaning that the yield from a freshwater mollusk is
higher than that of a saltwater oyster.
Freshwater environments are easier to maintain than saltwater environments. In the ocean there tend
to be more pollutants which harm the pearl production. Saltwater pearl farms must expend a lot of
energy to clean their oysters both before and after nucleation.
Finally, saltwater pearl productions cost more money than freshwater. Saltwater farms require divers,

2. ships, boats and complex equipment to access and maintain their saltwater pearl oysters. Freshwater
farms are able to maintain their productions on a smaller scale. The total cost put into producing a
saltwater pearl is considerable higher that what it takes to produce a freshwater pearl.
I hope this helps you understand the differences in these pearl processes. Let us know if you have any
questions!
