Saltwater Pearls have a more superficial, brilliant luster.
Freshwater Pearls are less lustrous and not as glossy.

It is generally believed that the luster of freshwater pearls will be slightly weaker than seawater pearls. In fact, I think there is a misunderstanding here. The output of freshwater pearls is much larger than that of seawater pearls, and the quality will be even more uneven, so it will bring some bad reviews to freshwater pearls.But in fact, Top quality freshwater pearls are not inferior to seawater pearls, so that there are some unscrupulous merchants in the market who sell good quality freshwater pearls as akoya seawater pearls.
Akoya pearls of the same quality and size are 4-5 times more expensive than freshwater pearls.
