Difference Between Fresh Water and Sea Water Pearl Gemstone

Precious Pearl Gemstone

Pearl gemstone have gained their popularity overages because of their sheer elegance and luster. However, did you know that not all pearls can be considered gemstones? The ones that have been harvested naturally can be called so.

Owe it to the time and the money that goes into harvesting a natural pearl. There is a cheaper alternative though, which is quite popular too- the freshwater pearl. Pearl gemstone basically found into the deep sea and ocean.

These are the few key differences between the two:

• Freshwater pearl harvests  in mussels, found in rivers and lakes. On the other hand, the seawater pearls originates in deep-sea like Thailand, Australia, Indonesia, and Tahiti. Akoya pearl originates in Japan as well as in China and Vietnam are most popular and high-quality varieties of saltwater pearl.

• There is a key difference in the harvesting process of the two. In these days most of the pearls are not natural. This means that a small piece of bread places in the mollusc, which covers it with nacre, the material pearls grow. These are known as cultured pearls. It is but natural that the time the pearl is left to grow, the better is the quality of the pearl gemstone. Moreover, the pearls that are cultivated for a long time are also more expensive.

• Indeed, most saltwater pearls are not natural, but cultured.  Naturally occurring pearls are difficult to  find and therefore their cheaper alternatives have gained popularity.

• There is a basic difference in the luster of the two. The nacre of freshwater pearls is denser and differs in composition with the saltwater pearls. Freshwater pearls are less lustrous and not glossy. However, the recent farming techniques have taken the quality of the pearl a notch higher.

• The Nacre coating in saltwater pearl is thinner, ranging from as low as 0.5 mm to 0.6 mm. Freshwater pearls are entirely makes of nacre. The basic reason for this is, the core piece inserts in the mollusc in freshwater is much smaller than the one put in the saltwater ones.

• Freshwater pearls come in a great variety of shape and sizes, round, oval, etc. Seawater pearls are basically in the round, which is the most in-demand.

Pearl price depends on whether it is a freshwater or a seawater pearl. Freshwater pearls are cheaper for several reasons. It is because the muscles can provide a number of pearls at a given time. They are smaller in size and have an inferior shape and nacre coating. The new technique, however, has enhanced their size and luster. It must be noted here that saltwater pearls are more sought after because of their luster, round shape, and size.

• Durability is different in both cases. While seawater pearls are fragile, the freshwater pearls are durable because of the already-installed core and the thicker outer coating.

• Freshwater pearls harvests  in lakes and ponds. Whereas seawater pearls harvests  in the deep sea. Freshwater pearls have a softer luster as compared to saltwater pearls that have a superficial, yet brilliant luster.

• In the case of a freshwater pearl, a mollusk can produce close to 50 pearls. However, in the case of saltwater pearl, it is only one that produces and a huge one too. pearl gemstone price depends upon various factors.

• Saltwater pearls are known as the Akoya pearls. They harvests using the Akoya mollusk. The implants uses to start the pearls make of oyster shells and are typically a little smaller than the resulting pearl.  Akoya pearls take about 6 to 18 months to grow.

• Freshwater or cultured pearls originates in pearl farms. There the molluscs raise until they are mature enough to accept the pearl starter. Implanting the bead is a delicate procedure.

 

However, things are different for seawater pearls as they grow naturally from particles that might have entered the oyster by chance. Because of the rarity of such cases, the prices of naturally grown pearl gemstone is much higher than the easily available freshwater pearls.
