subject: Www.aypearl.com Teaches You Difference Between Freshwater Pearl And Seawater Pearl [print this page] Pearl jewelry has always been loved by women, and here we simply list several differences between freshwater pearl and seawater pearl.
1. Generally speaking, seawater pearl is bigger than freshwater pearl, seawater pearls circle were relatively spherical, and freshwater pearls are more and more oval, flat circle. Seawater pearls feel relatively exquisite, freshwater pearl jewelry feel thick, has the rough feeling
2. Freshwater and saltwater pearls may sometimes look quite similar, but they come from very different sources
Natural freshwater pearls form in various species of freshwater mussels, family Unionidae, which live in lakes, rivers, ponds and other bodies of fresh water. These freshwater pearl mussels occur not only in hotter climates, but also in colder more temperate areas such as Scotland.
Saltwater pearls grow within pearl oysters, family Pteriidae, which live in oceans.
3. Time taken to harvest is different:
A freshwater mollusk can create up to 50 pearls at a time. The process to grow a freshwater pearl takes between 4 to 6 years and is full of peril - risk of disease, pollution, etc. A successful harvest of freshwater pearls is a highly praised event.
The growing time of seawater pearl takes between 6 to 18 months - the slower the growing period the better as the nacre is smoother.
4. Because the pearls in the freshwater mollusk start from virtually nothing (a small piece of tissue from a freshwater oyster), they are essentially 100% nacre. It has thicker nacre than seawater pearl.
5. The content of medicinal ingredients in seawater pearl is higher than those in freshwater pearls.
The value of the pearls in fashion jewelry is determined by a combination of the luster, color, size, lack of surface flaw and symmetry that are appropriate for the type of pearl under consideration. With modern freshwater cultivation methods the freshwater pearls are of excellent quality - with excellent body, shape, and luster and can be on equal footing with that of Saltwater pearls. In some cases freshwater cultured pearls have exceeded the quality of Saltwater Pearls.
