On the light, from different angles to observe the pearls, we will find
pearls will be full of mystery, and with the angle change. Some, such as drops of dew sparkling pearls scattered in the early morning of the lotus leaf, and some pearls but mysterious ancient history if the Millennium from the copper mold. Why is this so?
This requires from Pearl about the structure and composition.
Decision pearl color There are two factors:
First, Pteria pigment secreted. Pigments will be different because the environment and shellfish species vary. Because the state of the environment is changing, so of course pearl colors bewildering.
Second, because the structure of pearls. Pearl is a 0.3 ~ 0.4μm thick layers of nacre composed. These parallel nacre, profiles showed concentric structures. Each nacre is very smooth, and is translucent. Therefore, when a light on the pearl, the part of the surface reflection, while others entered the pearl itself, was another layer of nacre reflection, of course, there will be a part of re-entry to the deeper layers of pearls. Therefore, in each nacre, there will be some light is reflected, but also part of the light was refracted, some light will pass through pearls (below).
Because of light reflection, so that looks bright and shiny pearl; as a result of light transmission, so that looks sparkling pearl; as a result of refraction, the light will interfere with the phenomenon of production, thereby creating a volatile colors.
Pearl's own color, the color surrounding environment, coupled with the refraction and interference generated by color, pearl dream becomes hazy, mysterious incomparable.
However the matter is far from simple, pearl of the United States and more from its rare and in the long history of it lay with the left of the Western story. And pearl-related story and certainly not an extraordinary one after another. This has its own reason, because the real good pearls, can be met without resort's.
In natural circumstances, can produce a good bead is extremely difficult, and in the artificial breeding conditions, we want a good pearls are absolutely not that easy. Because a pearl from its mother at birth (larvae) start to finish pearl breeding, as long as more than 5 years. During this period, the summers easy quarter of the food shortage situation will be on the bay at any time have a negative impact on growth, and thus have a negative impact on pearls. To harvest time, from where tens of thousands of pearls can be singled out 12 we believe that the satisfaction of pearls, if there is an emergence of a perfect pearl, it is simply a miracle.
