| A pearl kind |
| |
|
|
| Akoya pearl |
The Japanese Akoya pearl which succeeded in culture first in the world is rich, and there is much size of 10 mm or less also with sufficient gloss. |
|
| |
|
|
South sea pearl
(White and Black) |
It cultivates near the equator.
Size is large.
Although there is much 9 mm - 15 mm, it has taken 20 mm. |
|
| |
|
|
| Lakeside pearl |
Although the above-mentioned pearl can be taken in the sea, many lakeside pearls can be taken in China currently cultivated on a pond, a river, etc.
There is most quantity of production and there is much below 12 mm? about size. |
|
|
| |
 |
The thing of the thickness of a mother-of-pearl is rolled and it is called thickness.
It is said that the pearl with a "thick" volume has little aging. |
 |
|
| |
 |
| It is carried out in order of the following. |
1. Put in the core which becomes a shellfish with a pearl basis.
A mother-of-pearl coils around this at many layers, and a pearl is produced. |
| |
2. Perform a water survey and shellfish cleaning once during the period from tamaire to hamaage every week.
A situation is seen briskly, adjusting the depth which the shellfish has sunk with water temperature, or removing the oyster and acorn barnacle adhering to buying it. |
| |
3. Open a shellfish and take out a pearl.
Then, washing etc. are processed and it is again born to the pearl of pikapika. |
|
| |
 |
| ・If it uses, it will often certainly wipe. |
| |
Please do not keep it as it is after attaching a pearl, but wipe sweat, oil, cosmetics, etc. which were attached to the surface as finely as possible.
Doing so is a secret which makes a pearl withstand long use. |
| |
|
| ・It is not made together with other jewelry. |
| |
Let's put into somewhere else so that it may not come into contact with other jewelry, when keeping it.
The crack made by coming into contact with other jewelry can be prevented.
Since it becomes a cause which damages a pearl, keeping a pearl in the state of heat and high humidity or extreme dryness should avoid. |
| |
|
| ・Let's change thread once in two years. |
| |
Although thread of the necklace was silk thread once, the wire etc. are used for 化繊, such as vinylon and Tetoron, and it at first.
When it will use for about two years and there is slack, we recommend you exchange of thread. |
