General confusion about the definition of natural pearls, even among experts is 100 years since the introduction of cultured pearls stand. Many of the customers around the world have little knowledge of jewelry with natural pearls. They never developed an eye for a pearl, "because most of them never heard of. The scientific method for identifying the true natural pearl culture through X-ray.
Pearl jewelry primarily natural change, and many pearls purchased individually or in chains remain in private hands.
Decorated with enamel, rubies, diamonds and pearls with a sapphire one, many of them, all natural pearls, the crown of Emperor Rudolf II, from 1602 on!
Imperial Sceptre of Austria covers issued by a court jeweler Andreas Senbruck in 1612 with the decoration of the crown and adorned with pearls and Sapphire Blue.
The thickness of the nacre is the key in determining the pearls.
East is a gem reflecting a muted and become the most beautiful pearl found in the soft tissues of mussels.
Sometimes the ball roll loose in the housing and easily. Compared with tiny moons, has a hidden gem of a fire, the flame cold, and a lively, beautiful stone with a clean soul.
A simple method for the determination of natural pearls is the thickness of the layers of nacre.
You can do this by rolling a string of pearls on a white surface under a bright light to do so. Balls on the verge of a nervous breakdown when you blink. They seem to be brighter and darker than pearls. Flash shows the ball through the nacre. Pearl nodded, not are not natural pearls.
Fluoroscopy is another way to determine the natural pearls. Pearl conducted a concentrated light source or purpose of the flashlight. Maglight ideal for trying to do. shown in balls balls thick skin, as a dark spot around. Series of parallel strips of beads on the edge. These bands are layers of growth. Beads of these bands have a very thin shell, and therefore not pearls.
Another simple test to arrive at a definition of natural pearls to help us in the Pearl itself, which fell to the balls! I also had to dive deep to find the test of natural pearls. Testing of touch.
Old pearl natural pearls is not called "cold flame" for nothing. If the pearl is a gem of nature cool to the touch. Touch test test is particularly useful for determining natural pearls in antique ring settings like this, you will not be able to drill to check the thickness of the nacre, or run a test with a wink, which is useful for a pearl necklace. If you have a pearl necklace, as you might think, of course, is money well spent for your beads on the radiographs gemological laboratories.
Another test test natural pearl Sun said. This test includes a string of pearls in the sun. If they are very, very expensive, genuine pearls will not be quite natural under the sun. You can change the size, shape and color to see. If the ball is ideal for size, shape and color corrected, they will not be in the order of pearls.
Natural pearls are less transparent than cultured pearls. If you lined up the pearls of nature rather than against a dark background, like a box of black cloth and put it under a bright light, natural pearls as small, white, homogeneous sphere, without inner ring. If, however, for the Pearl, you'll see a thin brown line between the nacre and nucleus Pearl.
Another way to help determine natural pearls, having studied the options. If you see a Picasso in the apartment, you can be sure that this is not an original work of art. You can also get valuable information about the gem of authenticity, adding to the environment.
Natural pearls set in gold, silver or platinum. Frame, of course, even before the 1920 Setting rules is no rule written in stone, a large number of high-quality cultured pearl necklaces are high quality. Nevertheless, setting and age of jewels to provide information to help you get results.
If there is any doubt the tools used to test the gem microscope (pearlometer), but the test will be called the most effective use of an endoscope or a test of modern X-ray or undrilled pearls gram heat.
This is important, but note that sometimes the definition of pearls freshwater pearls, is virtually impossible. You can not even tell the difference x-ray these gems. Nucleus, regardless of fertilization or naturally degrade, and generally leave a small gap in the ball. The small difference is only proof that remained.
