In our last closer look article, we examined the differences between freshwater pearls and marine pearls.  We also considered cultured vs. natural pearls.  To review these topics see "A Closer Look at Pearls (part I)".

This time we will venture inside the lovely little gem itself. 

It has been said that pearls are the world's most radiant gem.  Whereas gemstones need to be processed (i.e., cut and polished) to achieve their splendor, pearls are created in a way that reveals their inner beauty naturally. 

Luster is as luster does

As we learned last time, all genuine pearls are a result of a biological process where an irritant is introduced inside the shell of a mollusk.  As a "defensive action", the oyster secretes multiple layers of nacre around the irritant.  The chemicals (calcium carbonate) found in the layers of nacre are what makes the pearl seem to glow from within.  The rays of light passing along the surface of the pearl will reflect and refract not only from it's own surface, but also off the concentric inner layers as well.  This is what we call luster.  High luster pearls are usually a result of more layers of nacre. 

Nature's individual creations

Because pearls are created naturally, their surfaces are usually imperfect.  (Can any of us truthfully say that we don't have any quirky little imperfections ourselves?)  From the lumps and bumps to their cute little rings of formed nacre, pearls are as individual as people.  And just like people, their individuality speaks to the experience of their existence.  

Caring for your pearls

Pearls are made of a relatively soft material (especially when compared to gemstones).  To prevent scratching, you should store your pearls separately from your other jewelry.  Also, you should periodically wipe your pearls with a soft cloth to remove any body oils, perfume residue, and dirt.  If you take special care, your pearls should be able to maintain their lustrous beauty for years. 

To answer the question...

I don't know if it's even possible to have a discussion on pearls without answering one question:  Yes, you can tell the difference between genuine pearls and imitation pearls by rubbing them gently across your teeth.  (The fako junko pearls will feel smooth and slippery while the genuine pearls will feel slightly gritty.)
